COVID-19 causes more severe disease than seasonal influenza.

What is a coronavirus?

Coronaviruses are a large family of viruses which may cause illness in animals or humans.  In humans, several coronaviruses are known to cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered coronavirus causes coronavirus disease COVID-19.

 

What is COVID-19?

COVID-19 is the infectious disease caused by the most recently discovered coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019. COVID-19 is now a pandemic affecting many countries globally.

What are the symptoms of COVID-19?

The most common symptoms of COVID-19 are fever, dry cough, and tiredness. Other symptoms that are less common and may affect some patients include aches and pains, nasal congestion, headache, conjunctivitis, sore throat, diarrhoea, loss of taste or smell or a rash on skin or discoloration of fingers or toes. These symptoms are usually mild and begin gradually. Some people become infected but only have very mild symptoms.

Most people (about 80%) recover from the disease without needing hospital treatment. Around 1 out of every 5 people who gets COVID-19 becomes seriously ill and develops difficulty breathing. Older people, and those with underlying medical problems like high blood pressure, heart and lung problems, diabetes, or cancer, are at higher risk of developing serious illness.  However, anyone can catch COVID-19 and become seriously ill.  People of all ages who experience fever and/or  cough associated with difficulty breathing/shortness of breath, chest pain/pressure, or loss of speech or movement should seek medical attention immediately. If possible, it is recommended to call the health care provider or facility first, so the patient can be directed to the right clinic.

What should I do if I have COVID-19 symptoms and when should I seek medical care?

If you have minor symptoms, such as a slight cough or a mild fever, there is generally no need to seek medical care. Stay at home, self-isolate and monitor your symptoms. Follow national guidance on self-isolation.

However, if you live in an area with malaria or dengue fever it is important that you do not ignore symptoms of fever.  Seek medical help.  When you attend the health facility wear a mask if possible, keep at least 1 metre distance from other people and do not touch surfaces with your hands. If it is a child who is sick help the child stick to this advice.

Seek immediate medical care if you have difficulty breathing or pain/pressure in the chest. If possible, call your health care provider in advance, so he/she can direct you to the right health facility.

How does COVID-19 spread?

People can catch COVID-19 from others who have the virus. The disease spreads primarily from person to person through small droplets from the nose or mouth, which are expelled when a person with COVID-19 coughs, sneezes, or speaks. These droplets are relatively heavy, do not travel far and quickly sink to the ground. People can catch COVID-19 if they breathe in these droplets from a person infected with the virus.  This is why it is important to stay at least 1 meter) away from others. These droplets can land on objects and surfaces around the person such as tables, doorknobs and handrails.  People can become infected by touching these objects or surfaces, then touching their eyes, nose or mouth.  This is why it is important to wash your hands regularly with soap and water or clean with alcohol-based hand rub.

Can COVID-19 be caught from a person who has no symptoms?

COVID-19 is mainly spread through respiratory droplets expelled by someone who is coughing or has other symptoms such as fever or tiredness. Many people with COVID-19 experience only mild symptoms. This is particularly true in the early stages of the disease. It is possible to catch COVID-19 from someone who has just a mild cough and does not feel ill.

Some reports have indicated that people with no symptoms can transmit the virus. It is not yet known how often it happens. WHO is assessing ongoing research on the topic and will continue to share updated findings.

How can we protect others and ourselves if we don’t know who is infected?

Practicing hand and respiratory hygiene is important at ALL times and is the best way to protect others and yourself.

When possible maintain at least a 1 meter distance between yourself and others. This is especially important if you are standing by someone who is coughing or sneezing.  Since some infected persons may not yet be exhibiting symptoms or their symptoms may be mild, maintaining a physical distance with everyone is a good idea if you are in an area where COVID-19 is circulating. 

What should I do if I have come in close contact with someone who has COVID-19?

If you have been in close contact with someone with COVID-19, you may be infected.

Close contact means that you live with or have been in settings of less than 1 metre from those who have the disease. In these cases, it is best to stay at home.

However, if you live in an area with malaria or dengue fever it is important that you do not ignore symptoms of fever. Seek medical help. When you attend the health facility wear a mask if possible, keep at least 1 metre distant from other people and do not touch surfaces with your hands. If it is a child who is sick help the child stick to this advice.

If you do not live in an area with malaria or dengue fever please do the following:

  • If you become ill, even with very mild symptoms you must self-isolate
  • Even if you don’t think you have been exposed to COVID-19 but develop symptoms, then self-isolate and monitor yourself
  • You are more likely to infect others in the early stages of the disease when you just have mild symptoms, therefore early self-isolation is very important.
  • If you do not have symptoms, but have been exposed to an infected person, self-quarantine for 14 days.

If you have definitely had COVID-19 (confirmed by a test) self-isolate for 14 days even after symptoms have disappeared as a precautionary measure – it is not yet known exactly how long people remain infectious after they have recovered. Follow national advice on self-isolation.

What does it mean to self-isolate?

Self-isolation is an important measure taken by those who have COVID-19 symptoms to avoid infecting others in the community, including family members.

Self-isolation is when a person who is experiencing fever, cough or other COVID-19 symptoms stays at home and does not go to work, school or public places. This can be voluntarily or based on his/her health care provider’s recommendation. However, if you live in an area with malaria or dengue fever it is important that you do not ignore symptoms of fever. Seek medical help. When you attend the health facility wear a mask if possible, keep at least 1 metre distant from other people and do not touch surfaces with your hands. If it is a child who is sick help the child stick to this advice.

If you do not live in an area with malaria or dengue fever please do the following:

–  If a person is in self-isolation, it is because he/she is ill but not severely ill (requiring medical attention)

  • have a large, well-ventilated with hand-hygiene and toilet facilities
  • If this is not possible, place beds at least 1 metre apart
  • Keep at least 1 metre from others, even from your family members
  • Monitor your symptoms daily
  • Isolate for 14 days, even if you feel healthy
  • If you develop difficulty breathing, contact your healthcare provider immediately – call them first if possible
  • Stay positive and energized by keeping in touch with loved ones by phone or online, and by exercising yourself at home.

What should I do if I have no symptoms, but I think I have been exposed to COVID-19? What does it mean to self-quarantine?

To self-quarantine means to separate yourself from others because you have been exposed to someone with COVID-19 even though you, yourself, do not have symptoms. During self-quarantine you monitor yourself for symptoms.  The goal of the self-quarantine is to prevent transmission.  Since people who become ill with COVID-19 can infect people immediately self-quarantine can prevent some infections from happening.  .

In this case:

  • Have a large, well-ventilated single room with hand hygiene and toilet facilities
  • If this is not available place beds at least 1 metre apart.
  • Keep at least 1-metre distance from others, even from your family members.
  • Monitor your symptoms daily
  • Self-quarantine for 14 days, even if you feel healthy
  • If you develop difficulty breathing, contact your healthcare provider immediately – call them first if possible.
  • Stay positive and energized by keeping in touch with loved ones by phone or online, and by exercising yourself at home.

However, if you live in an area with malaria or dengue fever it is important that you do not ignore symptoms of fever.  Seek medical help.  When you attend the health facility wear a mask if possible, keep at least 1 metre distant from other people and do not touch surfaces with your hands. If it is a child who is sick help the child stick to this advice. 

What is the difference between self-isolation, self-quarantine and distancing?

Quarantine means restricting activities or separating people who are not ill themselves but may have been exposed to COVID-19. The goal is to prevent spread of the disease at the time when people just develop symptoms..

Isolation means separating people who are ill with symptoms of COVID-19 and may be infectious to prevent the spread of the disease.

Physical distancing means being physically apart. WHO recommends keeping at least 1metre distance from others. This is a general measure that everyone should take even if they are well with no known exposure to COVID-19. 

Can children or adolescents catch COVID-19?

Research indicates that children and adolescents are just as likely to become infected as any other age group and can spread the disease.

Evidence to date suggests that children and young adults are less likely to get severe disease, but severe cases can still happen in these age groups.

Children and adults should follow the same guidance on self-quarantine and self-isolation if there is a risk they have been exposed or are showing symptoms. It is particularly important that children avoid contact with older people and others who are at risk of more severe disease.

What can I do to protect myself and prevent the spread of disease?

Stay aware of the latest information on the COVID-19 outbreak, available on the WHO website and through your national and local public health authority. Most countries around the world have seen cases of COVID-19 and many are experiencing outbreaks. Authorities in China and some other countries have succeeded in slowing their outbreaks. However, the situation is unpredictable so check regularly for the latest news.

You can reduce your chances of being infected or spreading COVID-19 by taking some simple precautions:

  • Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water. Why? Washing your hands with soap and water or using alcohol-based hand rub kills viruses that may be on your hands.
  • Maintain at least 1 metre distance between yourself and others. Why? When someone coughs, sneezes, or speaks they spray small liquid droplets from their nose or mouth which may contain virus. If you are too close, you can breathe in the droplets, including the COVID-19 virus if the person has the disease.
  • Avoid going to crowded places. Why? Where people come together in crowds, you are more likely to come into close contact with someone that has COVID-19 and it is more difficult to maintain physical distance of 1 metre.
  • Avoid touching eyes, nose and mouth. Why? Hands touch many surfaces and can pick up viruses. Once contaminated, hands can transfer the virus to your eyes, nose or mouth. From there, the virus can enter your body and infect you.
  • Make sure you, and the people around you, follow good respiratory hygiene. This means covering your mouth and nose with your bent elbow or tissue when you cough or sneeze. Then dispose of the used tissue immediately and wash your hands. Why? Droplets spread virus. By following good respiratory hygiene, you protect the people around you from viruses such as cold, flu and COVID-19.
  • Stay home and self-isolate even with minor symptoms such as cough, headache, mild fever, until you recover. Have someone bring you supplies. If you need to leave your house, wear a mask to avoid infecting others. Why? Avoiding contact with others will protect them from possible COVID-19 and other viruses.
  • If you have a fever, cough and difficulty breathing, seek medical attention, but call by telephone in advance if possible and follow the directions of your local health authority. Why? National and local authorities will have the most up to date information on the situation in your area. Calling in advance will allow your health care provider to quickly direct you to the right health facility. This will also protect you and help prevent spread of viruses and other infections.
  • Keep up to date on the latest information from trusted sources, such as WHO or your local and national health authorities. Why? Local and national authorities are best placed to advise on what people in your area should be doing to protect themselves.

Is there a vaccine, drug or treatment for COVID-19?

While some western, traditional or home remedies may provide comfort and alleviate symptoms of mild COVID-19, there are no medicines that have been shown to prevent or cure the disease. WHO does not recommend self-medication with any medicines, including antibiotics, as a prevention or cure for COVID-19. However, there are several ongoing clinical trials of both western and traditional medicines. WHO is coordinating efforts to develop vaccines and medicines to prevent and treat COVID-19 and will continue to provide updated information as soon research results become available.

The most effective ways to protect yourself and others against COVID-19 are to:

  • Clean your hands frequently and thoroughly
  • Avoid touching your eyes, mouth and nose
  • Cover your cough with the bend of elbow or tissue. If a tissue is used, discard it immediately and wash your hands.
  • Maintain a distance of at least 1 metre from others. 

Does WHO recommend wearing medical masks to prevent the spread of COVID-19?

  • Currently, there is not enough evidence for or against the use of masks (medical or other) in healthy individuals in the wider community. However, WHO is actively studying the rapidly evolving science on masks and continuously updates its guidance.
  • Medical masksare recommended primarily in health care settings, but can be considered in other circumstances (see below). Medical masks should be combined with other key infection prevention and control measures such as hand hygiene and physical distancing.

·       Healthcare workers

  • Why?Medical masks and respirators such as N95, FFP2 or equivalent are recommended for and should be reserved for, healthcare workers while giving care to patients. Close contact with people with suspected or confirmed COVID-19 and their surrounding environment are the main routes of transmission, which means healthcare workers are the most exposed.

·       People who are sick and exhibiting symptoms of COVID-19

  • Why?Anyone who is sick, with mild symptoms such as muscle aches, slight cough, sore throat or fatigue, should isolate at home and use a medical mask according to WHO’s recommendation on home care of patients with suspected COVID-19. Coughing, sneezing or talking can generate droplets that cause can spread the infection. These droplets can reach the face of others nearby and land on the surrounding environment. If an infected person coughs, sneezes, or talks while wearing a medical mask, this can help to protect those nearby from infection. If a sick person needs to go to a health facility they should wear a medical mask.

·       Anyone taking care of a person at home who is sick with COVID-19

  • Why?Those caring for individuals who are sick with COVID-19 should wear a medical mask for protection. Again, close, frequent and prolonged contact with someone with COVID-19 puts caretakers at high risk. National decision makers may also choose to recommend medical mask use for certain individuals using a risk-based approach. This approach takes into consideration the purpose of the mask, risk of exposure and vulnerability of the wearer, the setting, the feasibility of use and the types of masks to be considered.

 

How to properly wear a medical mask?

If you choose to wear a mask:

  1. Before touching the mask, clean hands with an alcohol-based hand rub or soap and water
  2. Take the mask and inspect it for tears or holes.
  3. Orient which side is the top side (where the metal strip is).
  4. Ensure the proper side of the mask faces outwards (the coloured side).
  5. Place the mask to your face. Pinch the metal strip or stiff edge of the mask so it moulds to the shape of your nose.
  6. Pull down the mask’s bottom so it covers your mouth and your chin.
  7. Do not touch the mask while you are wearing it for protection.
  8. After use, take off the mask with clean hands; remove the elastic loops from behind the ears while keeping the mask away from your face and clothes, to avoid touching potentially contaminated surfaces of the mask.
  9. Discard the mask in a closed bin immediately after use. Do not reuse the mask.
  10. Perform hand hygiene after touching or discarding the mask – Use alcohol-based hand rub or, if visibly soiled, wash your hands with soap and water.

Be aware that there is a global shortage of medical masks (both surgical masks and N95 masks). These should be reserved as much as possible for health care workers.

Remember that masks are not a substitute for other, more effective ways to protect yourself and others against COVID-19 such as frequently washing your hands, covering your cough with the bend of elbow or tissue and maintain a distance of at least 1 meter from others.

Follow the advice of your national health authority on the use of masks.

How long does it take after exposure to COVID-19 to develop symptoms?

The time between exposure to COVID-19 and the moment when symptoms start is commonly around five to six days but can range from 1 – 14 days.

What is the connection between COVID-19 and animals?

COVID-19 is spread through human-to-human transmission.

We already know a lot about other viruses in the coronavirus family and most of these types of viruses have an origin in animals. The COVID-19 virus (also called SARS-CoV-2) is a new virus in humans. The possible animal source of COVID-19 has not yet been confirmed but research is ongoing.

WHO continues to monitor the latest research on this and other COVID-19 topics and will update, as new findings are available.

 

 

Can I catch COVID-19 from my pet or other animals?

Several dogs and cats (domestic cats and tigers) in contact with infected humans have tested positive for COVID-19. In addition, ferrets appear to be susceptible to the infection. In experimental conditions, both cats and ferrets were able to transmit infection to other animals of the same species. However, there is no evidence that these animals can transmit the disease to humans and spread COVID-19. COVID-19 is mainly spread through droplets produced when an infected person coughs, sneezes, or speaks.

Minks raised in farms have also been detected with the virus. Most likely, they have been infected by farm workers. In a few instances, the minks that were infected by humans have transmitted the virus to other people. These are the first reported cases of animal-to-human transmission.

It is still recommended that people who are sick with COVID-19 and people who are at risk limit contact with companion and other animals. When handling and caring for animals, basic hygiene measures should always be implemented. This includes hand washing after handling animals, their food or supplies, as well as avoiding kissing, licking or sharing food.

WHO continues to monitor the latest research on this and other COVID-19 topics and will update as new findings are available.

How long does the virus survive on surfaces?

The most important thing to know about coronavirus on surfaces is that they can easily be cleaned with common household disinfectants that will kill the virus. Studies have shown that the COVID-19 virus can survive for up to 72 hours on plastic and stainless steel, less than 4 hours on copper and less than 24 hours on cardboard.

As, always clean your hands with an alcohol-based hand rub or wash them with soap and water. Avoid touching your eyes, mouth, or nose.

How to grocery shop safely?

When grocery shopping, keep at least 1-metre distance from others and avoid touching your eyes, mouth and nose. If possible, sanitize the handles of shopping trolleys or baskets before shopping. Once home, wash your hands thoroughly and also after handling and storing your purchased products.

There is currently no confirmed case of COVID-19 transmitted through food or food packaging.

How to wash fruits and vegetables?

Fruits and vegetables are important components of a healthy diet. Wash them the same way you should do under any circumstance: before handling them, wash your hands with soap and water. Then, wash fruits and vegetables thoroughly with clean water, especially if you eat them raw.

Are antibiotics effective in preventing or treating COVID-19?

No. Antibiotics do not work against viruses; they only work on bacterial infections. COVID-19 is caused by a virus, so antibiotics do not work. Antibiotics should not be used as a means of prevention or treatment of COVID-19. In hospitals physicians will sometimes use antibiotics to prevent or treat secondary bacterial infections which can be a complication of COVID-19 in severely ill patients. They should only be used as directed by a physician to treat a bacterial infection.

Can I catch COVID-19 from the faeces of someone with the disease?

While initial investigations suggest the virus may be present in faeces in some cases, to date, there have not been reports of faecal-oral transmission of COVID-19. Additionally, there is no evidence to date on the survival of the COVID-19 virus in water or sewage.

WHO is assessing ongoing research on the ways COVID-19 is spread and will continue to share new findings on this topic.

 

 

 

 

 

 

Q&A: Masks and COVID-19

What is WHO’s view on masks?

Masks should be used as part of a comprehensive strategy of measures to suppress transmission and save lives; the use of a mask alone is not sufficient to provide an adequate level of protection against COVID-19. You should also maintain a minimum physical distance of at least 1 metre from others, frequently clean your hands and avoid touching your face and mask.

Medical masks can protect people wearing the mask from getting infected, as well as can prevent those who have symptoms from spreading them. WHO recommends the following groups use medical masks.

  • Health workers
  • Anyone with symptoms suggestive of COVID-19, including people with mild symptoms 
  • People caring for suspect or confirmed cases of COVID-19 outside of health facilities

Medical masks are also recommended for these at-risk people, when they are in areas of widespread transmission and they cannot guarantee a distance of at least 1 metre from others:

  • People aged 60 or over
  • People of any age with underlying health conditions

 

Non-medical, fabric masks are being used by many people in public areas, but there has been limited evidence on their effectiveness and WHO does not recommend their widespread use among the public for control of COVID-19. However, for areas of widespread transmission, with limited capacity for implementing control measures and especially in settings where physical distancing of at least 1 metre is not possible – such as on public transport, in shops or in other confined or crowded environments – WHO advises governments to encourage the general public to use non-medical fabric masks.

Does WHO advise the use of non-medical, fabric masks in the general public?

WHO recommends that people always consult local authorities on recommended practices in their area.

If there is widespread community transmission, and especially in settings where physical distancing cannot be maintained, governments should encourage the general public to wear a fabric mask. WHO also provides details on the composition of a fabric mask and how to safely wear one.

What is WHO recommending to countries that are considering the use of masks for the general public?

For countries that are considering the use of masks, WHO advises decision-makers to apply a risk-based approach to decide where, when and what type of masks should be used.  WHO advises decision makers to consider the following:

Purpose of mask use: if the intention is preventing the wearer transmitting infection to others (source control) or to offer protection to the wearer against infection (prevention).

Risk of exposure to COVID-19 to the population or individual:

  • Population level exposure measured by the amount of COVID-19 circulation in the community: that is, if there is known or suspected community transmission occurring.
  • Individual level exposure depending on a person’s occupation: e.g., individuals working in close contact with the public (e.g., community health worker, cashier).

Vulnerability of the mask wearer/population: for example, if supplies are adequate, medical masks should be used by people with pre-existing medical conditions, such as chronic respiratory disease, cardiovascular disease, cancer, immunocompromised patients or diabetes mellitus of any age, or people aged 60 and over.

Setting in which the population lives: settings with high population density (e.g. refugee camps, those living in cramped conditions) and settings where individuals are unable to keep a safe distance (e.g. crowded buses or other transport).

Feasibility: availability and costs of masks, access to clean water to wash non-medical masks, and ability of mask wearers to tolerate adverse effects of wearing a mask.

Type of mask: medical mask versus non-medical mask. Medical masks should be prioritized for health workers, symptomatic people and their caregivers.

In addition to these factors, potential advantages of the use of masks by the general population in the community setting include reducing potential exposure risk from an infected person during the ‘pre-symptomatic’ period or if an infected person is asymptomatic (that is when they may not have symptoms).

There are potential risks and disadvantages that should be taken into account in any decision-making process on the use of masks:

  • Non-medical or fabric masks could increase potential for COVID-19 to infect a person if the mask is contaminated by dirty hands and touched often, or kept on other parts of the face or head and then placed back over the mouth and nose
  • Depending on the type of mask used, could cause difficulty in breathing
  • They can lead to facial skin breakdown
  • They can lead to difficulty with communicating clearly
  • They can be uncomfortable to wear
  • It is possible that mask use, with unclear benefits, could create a false sense of security in the wearer, leading to diminished practice of recognized beneficial preventive measures such as physical distancing and hand hygiene. 

 

What types of masks are used against the spread of COVID-19?

  • Medical masks (also known as surgical masks):these are made from a minimum of three layers of synthetic nonwoven materials, and configured to have filtration layers sandwiched in the middle. These masks are available in different thicknesses, have various levels of fluid-resistance and two levels of filtration. These medical masks reduce the respiratory droplets from the wearer to others and to the environment. They also prevent transmission of the virus from others to the wearer.
  • Hands should be cleaned with alcohol-based hand rub or soap and water before putting on a clean mask and after removing the mask. These masks should be worn tightly on the face. The wearer should avoid touching the mask while it is on the face and the mask should be immediately discarded if it becomes moist. Importantly, wearing a mask must be combined with other preventive measures including performing frequent hand hygiene and physical distancing of at least 1 metre.

 

  • Respirators (also known as filtering face piece respirators – FFP) and available at different performance levels such as FFP2, FFP3, N95, N99):these are specifically designed for healthcare workers who provide care to COVID-19 patients in settings and areas where aerosol generating procedures are undertaken. Healthcare workers should be fit tested before using a respirator to ensure that they are wearing the correct size.
  • Non-medical masks (also known as fabric masks, home-made masks, DIY masks) can act as a barrier to prevent the spread of the virus from the wearer to others.
  • They can be purchased commercially or handmade, and are generally not standardized like medical masks. There are numerous types of fabric masks, they should cover the nose, mouth, and chin and be secured with elastic loops or ties, include multiple layers, be washable and reusable.
  • Remember, the use of a fabric mask alone is not sufficient to provide an adequate level of protection. Maintain a minimum physical distance of at least 1 metre from others, frequently clean your hands and continue to avoid touching your face and the mask.
  • WHO will be referring to non-medical masks as fabric masks.

 

Which individuals should wear medical masks in the context of COVID-19 according to WHO?

  • It is important to remember that the use of masks should be combined with other key infection prevention and control measures such as hand hygiene and physical distancing, as they do not protect against COVID-19 on their own.
  • WHO recommends the use of medical masks for the following individuals:

·       Health workers

  • Why? Health workers are the most likely to be exposed to the COVID-19 virus because they are in close contact with patients with suspected or confirmed COVID-19 and their surrounding environment. However, there are also reports of many health workers who are infected with the COVID-19 virus outside of the health facilities.
  • In areas where there are many people infected with COVID-19 in the community, health workers and caregivers should wear a medical mask while in clinical areas throughout the shift (apart from eating and drinking or needing to change the mask for specific reasons). This includes any clinical area, and in particular, triage and emergency rooms, family physician/GP practices, outpatient departments, COVID-19 dedicated units, haematological, cancer and transplant units, long-term health and residential facilities. It includes doctors, nurses, midwives, cleaners, and others working in clinical areas.
  • This is in addition to the previously WHO recommended practices that health workers caring for suspect or confirmed COVID-19 patients should follow droplet/contact precautions where a medical mask is part of the PPE package of recommendations, that includes: surgical gown, gloves, medical mask, and eye protection.
  • Please note, this is different from respirators, which are recommended for use in the context of where aerosol generating procedures are performed in health settings for a suspect/confirmed COVID-19 patient. In these settings, WHO recommends the use of airborne and contact precautions.
  • Link to how safely put on and remove PPE for droplet/contact precautions for COVID-19.
  • COVID-19: How to put on and remove personal protective equipment (PPE)
  • More information can be found in the guidance document on Infection prevention and control during health care when novel coronavirus (nCoV) infection is suspected.
  • Infection prevention and control during health care when novel coronavirus (nCoV) infection is suspected

·       People who are sick and exhibiting symptoms of COVID-19 or may suspect they have COVID-19

  • Why?Anyone who is sick, even with mild symptoms such as muscle aches, slight cough, sore throat or fatigue, should isolate at home and use a medical mask. Coughing, sneezing or talking can generate droplets that can spread the infection. These droplets can reach the face of others nearby or land on the surrounding environment. If an infected person coughs, sneezes, or talks wearing a medical mask, this helps to protect those nearby from infection. Sick people needing to go to a health facility should wear a medical mask. 

·       Anyone taking care of a person at home who is sick with COVID-19

  • Why?Those caring for individuals who are sick with COVID-19 should wear a medical mask for protection. Close and frequent contact with someone with COVID-19 can put those caring for them at high risk.

·       People 60 years old and over or anyone with pre-existing medical conditions (such as diabetes, high blood pressure, heart disease, lung disease, or cancer)

  • Why?These people should wear a medical mask for protection because they are at a higher risk of becoming seriously ill with the disease and dying.

  • Remember, the use of a fabric mask alone is not sufficient to provide an adequate level of protection. Maintain a minimum physical distance of at least 1 metre from others, frequently clean your hands and avoid touching your eyes, mouth, and nose while wearing a mask.
  • WHO recommends that people always consult local authorities on recommended practices in their area.

How should I use and wear a medical mask?

Medical masks should only be used by:

  • Health workers
  • Anyone with symptoms suggestive of COVID-19, including mildly ill people 
  • People caring for suspect or confirmed cases of COVID-19 outside of health facilities
  • People aged 60 or over
  • People with underlying health conditions

How to put on and take off a medical mask:

  • Before touching the mask, clean your hands with an alcohol-based hand rub or soap and water 
  • Inspect the mask for tears or holes; do not use a mask that has previously been worn or is damaged.
  • Verify which side is the top – this is usually where the metal strip is
  • Then, identify the inside of the mask, which is usually the white side.
  • Place the mask on your face covering your nose, mouth and chin, making sure that there are no gaps between your face and the mask.
  • Pinch the metal strip so it moulds to the shape of your nose.
  • Remember, do not touch the front of the mask while using it to avoid contamination; if you accidentally touch it, and clean your hands.  

How to take off a medical mask:

  • Before touching the mask, clean your hands with an alcohol-based hand rub or soap and water 
  • Remove the straps from behind the head or ears, without touching the front of the mask.
  • As you remove the mask, lean forward and pull the mask away from your face.  
  • Medical masks are for single use only; discard the mask immediately, preferably into a closed bin.
  • Clean your hands after touching the mask.
  • Be aware of the condition of the mask; replace it if it gets soiled or damp.

Remember, a mask alone cannot protect you from COVID-19. It must be combined with other measures, including maintaining at least one metre distance from each other, washing your hands frequently and avoiding touching your face while wearing a mask.

Stay safe and help prevent the spread of COVID-19! 

Does WHO recommend the use of fabric masks for the general public?

At the present time, the widespread use of masks everywhere is not supported by high-quality scientific evidence, and there are potential benefits and harms to consider.

However, there are some settings in which it may not be possible to keep physical distancing and the use of a mask could be helpful to provide a barrier to limit the spread of potentially infectious droplets from someone who is infected. In addition, there is some evidence which suggests that some infected people without showing symptoms may be able to transmit the virus others.

For this reason, WHO advises that governments should encourage the use of non-medical fabric masks, which can act as a barrier to prevent the spread of the virus from the wearer to others where there are many cases of COVID-19, for people in the general public where physical distancing of at least 1 metre is not possible – such as, on public transport, in shops or in other confined or crowded environments.

It is important to note that masks should only be used as part of a comprehensive strategy. Masks on their own will not protect you from COVID-19. People should also clean their hands frequently and maintain a distance of at least 1 metre from others. 

Since there are many types of fabric masks available, does WHO have any guidance on which masks to use?

WHO is actively studying and encouraging research on the science of masks. New research findings identified the following preferable types of fabrics, number of layers and the composition of a non-medical, fabric mask:

  • an inner layer of absorbent material such as cotton
  • a middle layer of non-woven material such as polypropylene 
  • an outer layer of non-absorbent material, such as polyester or polyester blend

More information on the types of materials and their effectiveness can be found in the updated mask guidance document – 

Coronavirus disease (COVID-19) technical guidance: Infection prevention and control / WASH

Make sure to construct or purchase a mask that lets you breathe while talking and walking briskly.

Remember, the use of a fabric mask alone is not sufficient to provide an adequate level of protection. Maintain a minimum physical distance of at least 1 metre from others and frequently clean your hands.

WHO recommends that people always consult local authorities on recommended practices in their area.

 

How should I wear and care for a fabric mask?

Using a fabric mask:

  • Clean your hands before putting on the mask. 
  • Inspect the mask for tears or holes, do not use a mask that is damaged.
  • Adjust the mask to cover your mouth, nose, and chin, leaving no gaps on the sides.
  • Avoid touching the mask while wearing it.
  • Change your mask if it gets dirty or wet.
  • Clean your hands before taking off the mask.
  • Take off the mask by removing it from the ear loops, without touching the front of the mask.
  • Clean your hands after removing the mask.

Caring for a fabric mask:

  • If your fabric mask is not dirty or wet and you plan to reuse it, put it in a clean plastic, resealable bag. If you need to use it again, hold the mask at the elastic loops when removing it from the bag.
  • Wash fabric masks in soap or detergent and preferably hot water (at least 60 degrees) at least once a day.
  • If hot water is not available, wash the mask in soap/detergent and room-temperature water, followed by either boiling the mask for 1 minute OR; by soaking the mask in 0.1% chlorine for 1 minute and thoroughly rinsing the mask with room temperature water (there should not be any toxic residue of chlorine on the mask).
  • Make sure you have your own mask and do not share it with others.

 Remember, the use of a fabric mask alone is not sufficient to provide an adequate level of protection. Maintain a minimum physical distance of at least 1 metre from others and frequently clean your hands.

Does WHO recommend the use of gloves in the community to prevent transmission of COVID-19?

No, WHO does not recommend the use of gloves by people in the community. The wearing of gloves may increase risk of infection, since it can lead to self-contamination or transmission to others when touching contaminated surfaces and then the face.

Therefore, in public places such as supermarkets, in addition to physical distancing, WHO recommends the installation of public hand hygiene stations at the entrance and exit.

By widely improving hand hygiene practices, countries can help prevent the spread of the COVID-19 virus.

WHO recommends that people always consult local authorities on recommended practices in their area.

What are the key measures all people should do to protect themselves and others in the context of the COVID-19 pandemic?

It is an important reminder that in the context of the COVID-19 pandemic, everyone, regardless of the use of masks, should:

  • avoid groups of people and crowded spaces;
  • maintain physical distance of at least 1 meter from other people, especially from those who are sick;
  • clean your hands frequently, using an alcohol-based hand rub if hands are not visibly dirty, or soap and water;
  • cover your nose and mouth with a bent elbow or paper tissue when coughing or sneezing, dispose of the tissue and clean your hands immediately after use;
  • refrain from touching your mouth, nose, and eyes.

 

Above all, stay informed of the progress of the disease, pay attention to local authorities and their recommendations, and follow and encourage best practices.

Q&A: Older people and COVID-19

Who is at risk of developing severe disease?

Older people, and people of all ages with pre-existing medical conditions (such as diabetes, high blood pressure, heart disease, lung disease, or cancer) appear to develop serious illness more often than others.

What can older people do to prepare for COVID-19 in their community?

There is a lot that you can do to prepare for COVID-19 in your community.

  • Inform yourself of the special measures taken in your community as well as the services and the sources of reliable information that are availableduring the health emergency (e.g. home deliveries, psychosocial support, health ministry website, alternative access to your pension).

 

  • Create a list of the basic supplies that you will need for at least two weeks and try to get these delivered where possible (e.g. non-perishable food items, household products, batteries for assistive devices you may use, and prescription medicines). Alternatively, ask family members, caregivers, neighbours or community leaders to help with ordering and/or delivery of groceries or prescription medicines. Make sure that your mobile phone credit is topped up and identify a safe place to charge your phone regularly so that you can keep in contact with family and friends and reach emergency services if needed. 
  • Make a list of emergency numbers (e.g. COVID-19 local helpline, nearby hospital and health emergencies numbers, hotline for victims of abuse, psychosocial support hotline) and support contacts (e.g. family members and friends, main caregiver, community care worker, associations of older persons). If you live alone, you may wish to share this list and ask your neighbours, family or caregiver to be in touch regularly, for example, by phone or video chat.

 

  • Discuss with your health-care worker how your health needs can be addressed during COVID-19. This may involve postponing non-urgent appointments, talking to your doctor or health-care worker by phone or video chat instead of in person and/or revising your vaccination schedule.

 

  • If you rely on the support provided by a caregiver, identify with him or her another person that you trust to support your daily living and care needs in case your caregiver is unable to continue to provide care. Together, you can note down all the personal care and assistance that you require and how it should be provided and share it with this trusted person so that they can be ready to provide care in case of need. 

 

  • If you are the primary caregiver of another person who is care dependent (e.g. grandchild, older spouse, child with a disability), identify a person that you and the person that you care for trust to take on your caregiving responsibilities in case you fall sick. Local authorities or volunteer organizations that provide support in these situations in your community might be able to help.

 

  • If multiple people live in your home, if possible prepare a separate room or space in your home so that anyone showing symptoms compatible with COVID-19 can be isolated from others. If you do not have space for self-isolation, contact your community leaders or local health authorities to see if there is community space that could help you or other household members self-isolate.

 

  • Think about what matters most to you regarding care and support, including medical treatment, in case something happens to you and you are unable to make your own decisions. If you want to develop an advanced care plan to record your treatment and care wishes, you can talk about it with your health-care worker or someone that you trust. You can write down your wishes and share them with people you trust. 

How can I keep healthy on a daily basis during the COVID-19 pandemic?

You can follow these 10 steps to keep healthy during the COVID-19 pandemic.

  1. Keep to your regular routines as much as possible and maintain a daily schedule for yourself including sleeping, meals and activities.

 

  1. Stay socially connected. Speak to loved ones and people you trust every day or as much as possible, using the telephone, video-calls or messaging, through writing letters, etc. Use this time to share your feelings and to do common hobbies together.

 

  1. Be physically active every day. Reduce long periods of sitting and set up a daily routine that includes at least 30 minutes of exercise. Make sure to do activities that are safe and appropriate for your level of physical fitness as indicated by your health-care worker. You can use household chores as a way to keep physically active, follow an on-line class (e.g. Tai Chi, yoga) or choose your favourite music and dance to that.

 

  1. Drink water and eat healthy and well-balanced meals. This will keep you hydrated, help strengthen your immune system and lower the risk of chronic illnesses and infectious diseases.  For nutrition advice click here.

 

  1. Avoid smoking and drinking alcoholSmokers are likely to be more vulnerable to COVID-19 because smoking can affect lung capacity and because the act of smoking increases the possibility of transmission of virus from hand to mouth. Drinking alcohol not only disturbs your sleep but may also increase your risk of falls, weaken your immune system, and interact with any prescription medicines that you are taking. Limit the amount of alcohol you drink or don’t drink alcohol at all.

 

  1. Take breaks from news coverage about COVID-19 as prolonged exposure can cause feelings of anxiety and despair. Seek updates at specific times of the day from a reliable source like the WHO website click here or national or local channels in order to help you distinguish facts from rumours or scams.

 

  1. Engage in hobbies and activities that you enjoy or learn something new. Cognitive exercise such as reading a book or doing crosswords/Sudoku will keep your mind active and distract you from worrying. You can also use this time to keep a well-being diary.

 

  1. If you have ongoing health conditionstake your prescribed medicines and follow the advice of your health-care worker regarding any health visits or phone consultations.

 

  1. If you have an emergency medical condition that is not related to COVID-19, contact health emergencies immediately and ask what you should do next. Follow the instructions of the health-care worker.

 

  1. If stress, worry, fear or sadness get in the way of your daily activities for several days in a row, seek psychosocial support from available services in your community.  If you are subject to abuse or violence from others, tell someone you trust and report this to the relevant authorities. You can also seek support from dedicated helplines that may be available in your country.

 

What should I do if I have symptoms of COVID-19?

  • If you present symptoms related to COVID-19, seek medical advice. Call by phone first if possible and give information about pre-existing health conditions and medicines that you are taking. Follow the instructions of the health-care worker and monitor your symptoms regularly.

 

  • If you have difficulty breathing, contact health emergencies immediately as this may be due to a respiratory infection. Call by phone first if possible to learn what to do next.

 

  • If you live with others, make sure that you isolate yourself as soon as you suspect infectionby using the space that you identified in advance. You and other members of the household should also wear a medical mask as much as possible if these are available.

 

  • If you live with others and home care for COVID-19 is advised by your health-care worker, other household members should follow available guidance on home care for patients with COVID-19 presenting with mild symptoms and management of their contacts. 
  • If you live alone and home care for COVID-10 is advised by your health-care workerask your family, friends, neighbours, health-care worker or a local volunteer organisation to check in on you regularly and to provide support as needed following necessary guidance.

I have recently lost someone I care about. What advice do you have to help me cope?

Losing someone close to you is always hard, whatever the cause. During these extraordinary circumstances, when your usual routine may be disrupted and when funerals may not be permitted, it may be even harder. Following this advice may help.

  • Do not criticise yourself for how you feel. When you lose a family member or friend to COVID-19, you may experience a range of emotions.  You may also have difficulty sleeping or low levels of energy. All these feelings are normal and there is no right or wrong way to feel grief. 
  • Allow yourself time to process your emotions in response to your loss. You may think that the sadness and pain that you feel will never go away, but in most cases, these feelings lessen over time. 
  • Talk regularly with people that you trust about your feelings.
  • Keep to your routines as much as you feel able and try to focus on activities that bring you joy.
  • Seek advice and comfort from people that you trust (e.g. religious/faith leaders, mental health workers or other trusted members of your community) while maintaining physical distance (e.g. attending virtual mass)  
  • Think of alternative ways to say goodbye to the person who passed away such as writing a letter or dedicating a drawing to your loved one. These are small actions that can help you cope with grief and loss, particularly in situations where funeral services are not permitted.

Q&A: Tobacco and COVID-19

As a smoker, is my risk of getting the COVID-19 virus higher than that of a non-smoker?

At the time of preparing this Q&A, there are no peer-reviewed studies that have evaluated the risk of SARS-CoV-2 infection associated with smoking. However, tobacco smokers (cigarettes, water pipes, bidis, cigars, heated tobacco products) may be more vulnerable to contracting COVID-19, as the act of smoking involves contact of fingers (and possibly contaminated cigarettes) with the lips, which increases the possibility of transmission of viruses from hand to mouth. Smoking water pipes, also known as shisha or hookah, often involves the sharing of mouth pieces and hoses, which could facilitate the transmission of the COVID-19 virus in communal and social settings.

As a smoker, am I likely to get more severe symptoms if infected?

Smoking any kind of tobacco reduces lung capacity and increases the risk of many respiratory infections and can increase the severity of respiratory diseases. COVID-19 is an infectious disease that primarily attacks the lungs. Smoking impairs lung function making it harder for the body to fight off coronaviruses and other respiratory diseases.  Available research suggests that smokers are at higher risk of developing severe COVID-19 outcomes and death.  

As a vaper, am I more likely to be infected or to have more severe symptoms if infected?

There is no evidence about the relationship between e-cigarette use and COVID-19. However, existing evidence indicates that electronic nicotine delivery systems (ENDS) and electronic non-nicotine delivery systems (ENNDS), more commonly referred to as e-cigarettes, are harmful and increase the risk of heart disease and lung disorders.  Given that the COVID-19 virus affects the respiratory tract, the hand-to-mouth action of e-cigarette use may increase the risk of infection.

What about using smokeless tobacco, like chewing tobacco?

Using smokeless tobacco often involves some hand to mouth contact.  Another risk associated with using smokeless tobacco products, like chewing tobacco, is that the virus can be spread when the user spits out the excess saliva produced during the chewing process.

What does WHO recommend for tobacco users?

Given the risks to health that tobacco use causes, WHO recommends quitting tobacco use.  Quitting will help your lungs and heart to work better from the moment you stop.  Within 20 minutes of quitting, elevated heart rate and blood pressure drop. After 12 hours, the carbon monoxide level in the bloodstream drops to normal. Within 2-12 weeks, circulation improves and lung function increases. After 1-9 months, coughing and shortness of breath decrease. Quitting will help to protect your loved ones, especially children, from exposure to second-hand smoke. 

WHO recommends the use of proven interventions such as toll-free quit lines, mobile text-messaging cessation programmes, and nicotine replacement therapies (NRTs), among others, for quitting tobacco use.

What can I do to protect people from the risks associated with smoking, smokeless tobacco use and vaping?

  • If you smoke, use e cigarettes or use smokeless tobacco, now is a good time to quit completely.

 

  • Do not share devices like water pipes and e-cigarettes.

 

  • Spread the word about the risks of smoking, using e-cigarettes and using smokeless tobacco.

 

  • Protect others from the harms of second-hand smoke.

 

  • Know the importance of washing your hands, physical distancing, and not sharing any smoking or e -cigarette products.

 

  • Do not spit in public places

 

Does nicotine use affect my chances in the context of COVID-19?

There is currently insufficient information to confirm any link between tobacco or nicotine in the prevention or treatment of COVID-19. WHO urges researchers, scientists and the media to be cautious about amplifying unproven claims that tobacco or nicotine could reduce the risk of COVID-19. WHO is constantly evaluating new research, including that which examines the link between tobacco use, nicotine use, and COVID-19.

 

Q&A : Hydroxychloroquine and COVID-19

Why was the use of hydroxychloroquine temporarily suspended in the Solidarity Trial?

  • In light of recent publications of evidence on the safety and efficacy of hydroxychloroquine as a treatment for COVID-19 patients, the Executive Group of the Solidarity Trial decided to implement a temporary pause of the hydroxychloroquine arm within the trial as a precaution while the safety data is being reviewed.
  • As an example, an observational study published in the Lancet on 22 May found that, among 100 000 patients from multiple countries randomized to receive hydroxychloroquine, when used alone or with a macrolide, there was a higher mortality rate and an increased frequency of irregular heartbeats.
  • A final decision on the harm, benefit or lack of benefit of hydroxychloroquine will be made once the evidence has been reviewed by the Data Safety Monitoring Board. This review will include data from the Solidarity Trial and other ongoing trials, as well as any evidence published so far. It is expected by mid-June.

What will happen to the people who are currently enrolled in the hydroxychloroquine arm of the trial?

Those patients previously randomized to hydroxychloroquine treatment should continue to receive hydroxychloroquine until they finish their course of treatment. The use of hydroxychloroquine and chloroquine are accepted as generally safe for use in patients with autoimmune diseases or malaria.

What is WHO’s view of ongoing prophylaxis treatments followed in some countries, which include the use of hydroxychloroquine?

WHO is currently assessing the use of hydroxychloroquine on COVID-19 patients within the Solidarity Trial. The hydroxychloroquine arm has been paused as a precaution while the safety data is being reviewed.

Every country, particularly those with regulatory authorities, is in a position to advise its citizens regarding the use of any drug. Although hydroxychloroquine and chloroquine are already licensed products for treating other diseases, at this stage, these drugs have not been found to be effective in the treatment of COVID-19. In fact, warnings have been issued by many national authorities on the side effects of the drugs and their use has been limited in many countries to clinical trials under strict supervision in hospital settings.

WHO has cautioned physicians against recommending or administering unproven treatments to COVID-19 patients, and cautioned people against self-medicating with them. The consensus among world experts is that the potential exists but that far more studies are urgently needed to determine if existing antiviral drugs can be effective to treat COVID-19. If these treatments prove to be effective, they could reduce the burden of COVID-19.

What is the Solidarity Trial?

The Solidarity Trial is an international clinical trial to help find an effective treatment for COVID-19, launched by WHO and partners. It is hoped that one or more of the treatments under trial will result in improving clinical outcomes in COVID-19 patients and save lives. Other trials are on-going around the world in addition to the Solidarity Trial. 

Based on data from laboratory and clinical studies, Remdesivir, Lopinavir/Ritonavir, Lopinavir/Ritonavir with Interferon beta-1a, and hydroxychloroquine had been initially selected as treatment options. Following new evidence on the safety and efficacy of hydroxychloroquine as a treatment for hospitalized COVID-19 patients, enrolment for this drug was temporarily suspended on 24 May 2020.

Over 100 countries have expressed an interest in participating in the trial and WHO is actively supporting more than 60 of them, including with the following:

  • ethical and regulatory approvals of the WHO core protocol;
  • identification of hospitals participating in the trial;
  • training of hospital clinicians on the web-based randomization and data system;
  • Shipping the trial drugs as requested by each participating country.

To date, over 400 hospitals in 35 countries are actively recruiting patients and nearly 3500 patients have been enrolled from 17 countries.

An interim trial analysis will be produced and will be monitored by an independent group of experts as the global Data and Safety Monitoring Committee.

 

Q&A: Considerations for the cleaning and disinfection of environmental surfaces in the context of COVID-19 in non-health care settings

What areas should be prioritized for disinfection in non-health care settings?

Disinfection practices are important to reduce the potential for COVID-19 virus contamination in non-healthcare settings, such as in the home, office, schools, gyms, publicly accessible buildings, faith-based community centres, markets, transportation and business settings or restaurants. High-touch surfaces in these non-health care settings should be identified for priority disinfection such as door and window handles, kitchen and food preparation areas, counter tops, bathroom surfaces, toilets and taps, touchscreen personal devices, personal computer keyboards, and work surfaces.

Which surface disinfectants are effective against COVID-19 in non-health care setting environments?

In non-health care settings, sodium hypochlorite (bleach / chlorine) may be used at a recommended concentration of 0.1% or 1,000ppm (1 part of 5% strength household bleach to 49 parts of water). Alcohol at 70-90% can also be used for surface disinfection. Surfaces must be cleaned with water and soap or a detergent first to remove dirt, followed by disinfection.  Cleaning should always start from the least soiled (cleanest) area to the most soiled (dirtiest) area in order to not spread the dirty to areas that are less soiled.

All disinfectant solutions should be stored in opaque containers, in a well-ventilated, covered area that is not exposed to direct sunlight and ideally should be freshly prepared every day.

In indoor spaces, routine application of disinfectants to surfaces via spraying is not recommended for COVID-19. If disinfectants are to be applied, these should be via a cloth or wipe which is soaked in the disinfectant. 

What protection measures should people take when using disinfectants?

It is important to reduce your risk when using disinfectants:

  • The disinfectant and its concentration should be carefully selected to avoid damaging surfaces and to avoid or minimize toxic effects on household members (or users of public spaces).
  • Avoid combining disinfectants, such as bleach and ammonia, since mixtures can cause respiratory irritation and release potentially fatal gases.
  • Keep children, pets and other people away during the application of the product until it is dry and there is no odour.
  • Open windows and use fans to ventilate. Step away from odours if they become too strong. Disinfectant solutions should always be prepared in well-ventilated areas.
  • Wash your hands after using any disinfectant, including surface wipes.
  • Keep lids tightly closed when not in use. Spills and accidents are more likely to happen when containers are open.
  • Do not allow children to use disinfectant wipes. Keep cleaning fluids and disinfectants out of the reach of children and pets.
  • Throw away disposable items like gloves and masks if they are used during cleaning. Do not clean and re-use.
  • Do not use disinfectant wipes to clean hands or as baby wipes.
  • The minimum recommended personal protective equipment when disinfecting in non-health care settings is rubber gloves, waterproof aprons and closed shoes. Eye protection and medical masks may also be needed to protect against chemicals in use or if there is a risk of splashing.

 

Note: Where cleaning and disinfection are not possible on a regular basis due to resource limitations, frequent hand washing and avoiding touching the face should be the primary prevention approaches to reduce any potential transmission associated with surface contamination.

What is the guidance for the disinfection of outdoor spaces such as open markets, roads?

In outdoor spaces, large-scale spraying or fumigation in areas such as streets or open market places for the COVID-19 virus or other pathogens is not recommended. Streets and sidewalks are not considered as routes of infection for COVID-19. Spraying disinfectants, even outdoors, can be noxious for people’s health and cause eye, respiratory or skin irritation or damage.

This practice will be ineffective since the presence of dirt or rubbish for example, inactivates the disinfectant, and manual cleaning to physically remove all matter is not feasible. This is even less effective on porous surfaces such as sidewalks and unpaved walkways. Even in the absence of dirt or rubbish, it is unlikely that chemical spraying would adequately cover surfaces allowing the required contact time to inactivate pathogens. 

Are public systems for disinfecting individuals such as spraying via tunnel or chambers safe to use?

No. Spraying of individuals with disinfectants (such as in a tunnel, cabinet, or chamber) is not recommended under any circumstances. This practice could be physically and psychologically harmful and would not reduce an infected person’s ability to spread the virus through droplets or contact. Even if someone who is infected with COVID-19 goes through a disinfection tunnel or chamber, as soon as they start speaking, coughing or sneezing they can still spread the virus. 

The toxic effect of spraying with chemicals such as chlorine on individuals can lead to eye and skin irritation, bronchospasm due to inhalation, and potentially gastrointestinal effects such as nausea and vomiting. In addition to health safety concerns, the use of chlorine in large-scale spraying practices may prevent this resource from being used for important interventions such as drinking water treatment and environmental disinfection of health care facilities.

What are the recommended practices once back home after outdoor activities?

Thorough hand hygiene: washing hands with soap and water or using alcohol-based hand gel, should be performed before touching surfaces, items, pets, and people within the household environment.

While outside, people should always follow physical distancing measures, staying at least one metre from another person; perform hand hygiene by washing hands frequently with soap and water or using alcohol-based hand rub; follow good respiratory hygiene by covering your mouth and nose with your bent elbow or tissue when coughing or sneezing; avoid touching your eyes, nose and mouth; and avoid crowded places.

How should I clean food items from the grocery store, for example fruit, vegetables or packaged items?

There is no evidence to date of viruses that cause respiratory illnesses being transmitted via food or food packaging. Coronaviruses cannot multiply in food; they need an animal or human host to multiply.

The COVID-19 virus is generally thought to be spread from person to person through respiratory droplets. Currently, there is no evidence to support transmission of the COVID-19 virus associated with food.

Before preparing or eating food it is important to always wash your hands with soap and water for at least 40-60 seconds. Regular food safety and handling guidance should be followed.

Questions relating to consumers

Can I get COVID-19 from food?

There is currently no evidence that people can catch COVID-19 from food or food packaging. COVID-19 is a respiratory illness and the transmission route is through person-to-person contact and through direct contact with respiratory droplets generated when an infected person coughs or sneezes.

Can the virus live on the surface of foods (including fruits and vegetables, frozen foods, pre-packaged foods)?

Coronaviruses cannot multiply in food – they need a live animal or human host to multiply and survive.

How to wash fruits and vegetables? Just with water, or something else?

Washing fruit and vegetables with potable water is sufficient: it is recommended to follow the WHO 5-Keys to Safer Food

Can the virus live on the surface of food packaging? How long? Is it necessary to disinfect?

It is not necessary to disinfect food packaging materials, but hands should be properly washed after handling food packages and before eating.

How long is it to cook food? To what temperature to kill the virus?

This virus is not more resistant to heat than the usual viruses and bacteria found in food. As recommended for good hygiene practice, foods should be thoroughly cooked to at least 70°C.

What precautions should consumers take in grocery stores?

Consumers should maintain a safe physical distance of at least one metre from all other shoppers and staff while queuing before entering the store and while shopping in the store. If a trolley or basket is used while shopping, sanitize the handle before and after use. Hands should be sanitized before entering the store. Practice good coughing/sneezing etiquette while in the store. Avoid touching mouth, nose or eyes during shopping. Minimise direct hand contact with food by using available tongs and serving utensils. Use contactless payment rather than cash/notes (where feasible).  

Is food/grocery delivery safe?

Yes, if the provider follows good personal and food hygiene practices. After accepting food/grocery deliveries, hands should be washed with soap and water. 

What is the best household disinfectant for surfaces?

Regular household cleaning and disinfection products will effectively eliminate the virus from household surfaces.  For cleaning and disinfecting households with suspected or confirmed COVID19 illnesses – surface virucidal disinfectants, such as 0.05% sodium hypochlorite (NaClO) and products based on ethanol (at least 70%), should be used.

Is it still safe to go to food markets? Animal markets? Wet markets?

It should be safe provided it is possible to maintain a safe physical distance of at least one metre from all other shoppers and staff, it is possible to wash/sanitize hands, and that Good Manufacturing Practices and Good Hygienic Practices (GMP/GHP) standards are maintained in the market. For more recommendations on how to minimise the risk of transmission of emerging pathogens in wet markets
