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.
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.
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 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)
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:
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 1–metre 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:
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:
Does WHO recommend wearing medical masks to prevent the spread of COVID-19?
How to properly wear a medical mask?
If you choose to wear a mask:
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.
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.
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.
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:
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:
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:
What types of masks are used against the spread of COVID-19?
Which individuals should wear medical masks in the context of COVID-19 according to WHO?
How should I use and wear a medical mask?
Medical masks should only be used by:
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.
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:
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:
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.
It is an important reminder that in the context of the COVID-19 pandemic, everyone, regardless of the use of masks, should:
Above all, stay informed of the progress of the disease, pay attention to local authorities and their recommendations, and follow and encourage best practices.
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.
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.
What should I do if I have symptoms of COVID-19?
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.
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.
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?
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.
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.
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:
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.
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:
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.

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
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.
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
