1. How does COVID-19 spread?
People can catch COVID-19 from others who have the virus. The disease can spread from person to person through small droplets from the nose or mouth which are spread when a person with COVID-19 coughs or exhales. These droplets land on objects and surfaces around the person. Other people then catch COVID-19 by touching these objects or surfaces, then touching their eyes, nose or mouth. People can also catch COVID-19 if they breathe in droplets from a person with COVID-19 who coughs out or exhales droplets. This is why it is important to stay more than 1 meter (3 feet) away from a person who is sick.
2. What are the symptoms of COVID-19?
The most common symptoms of COVID-19 are fever, tiredness, and dry cough. Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhea. These symptoms are usually mild and begin gradually. Some people become infected but don’t develop any symptoms and don't feel unwell. Most people (about 80%) recover from the disease without needing special treatment. Around 1 out of every 6 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 problems or diabetes, are more likely to develop serious illness. People with fever, cough and difficulty breathing should seek medical attention.
3. How do I know if it is COVID-19 or just the common flu?
A COVID-19 infection has the same signs and symptoms as the common cold and you can only differentiate them through laboratory testing to determine the virus type. If you have fever, cough and difficulty breathing, you should seek medical attention and immediately isolate yourself from others. Call your local clinic/medical facility to inform them of your condition and relevant travel/exposure history. If you had been identified as a close contact of a case by the local Ministry of Health or WHO, please also indicate this. From here you will be advised if a medical assessment is necessary and how to get tested.
4. Can the virus that causes COVID-19 be transmitted through the air?
Studies to date suggest that the virus that causes COVID-19 is mainly transmitted through contact with respiratory droplets rather than through the air. See previous answer on “How does COVID-19 spread?”
5. What can I do to protect myself and prevent the spread of disease?
Protection measures for everyone 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. Many countries around the world have seen cases of COVID-19 and several have seen outbreaks. Authorities in China and some other countries have succeeded in slowing or stopping 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 meter (3 feet) distance between yourself and anyone who is coughing or sneezing. Why? When someone coughs or sneezes, 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 coughing has the disease.
- 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 can make you sick.
- 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. 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 if you feel unwell. If you have a fever, cough and difficulty breathing, seek medical attention and call in advance. 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 COVID-19 hotspots (cities or local areas where COVID-19 is spreading widely). If possible, avoid traveling to places – especially if you are an older person or have diabetes, heart or lung disease. Why? You have a higher chance of catching COVID-19 in one of these areas.
6. I am well and asymptomatic. Should I use a mask?
According to the WHO, for individuals without respiratory symptoms, a medical mask is not required, as no evidence is available on its usefulness to protect non-sick persons. However, masks might be worn in some countries according to local cultural habits. If masks are used, best practices should be followed on how to wear, remove, and dispose of them and on hand hygiene action after removal. For more information, visit the WHO guidance on use of masks in the community.
7. How likely am I to catch COVID-19?
The risk depends on where you are - and more specifically, whether there is a COVID-19 outbreak unfolding there. For most people in most locations the risk of catching COVID-19 is still low. However, there are now places around the world (cities or areas) where the disease is spreading. For people living in, or visiting, these areas the risk of catching COVID-19 is higher. Governments and health authorities are taking vigorous action every time a new case of COVID-19 is identified. Be sure to comply with any local restrictions on travel, movement or large gatherings. Cooperating with disease control efforts will reduce your risk of catching or spreading COVID-19.
COVID-19 outbreaks can be contained and transmission stopped, as has been shown in China and some other countries. Unfortunately, new outbreaks can emerge rapidly. It’s important to be aware of the situation where you are or intend to go. WHO publishes daily updates on the COVID-19 situation worldwide.

8. Are pregnant women more susceptible to the COVID-19 virus and will it harm the fetus?
We do not have information from published scientific reports about the susceptibility of pregnant women to COVID-19. Pregnant women experience immunologic and physiologic changes, which might make them more susceptible to viral respiratory infections, including COVID-19.
The virus that causes COVID-19 is thought to spread mainly by close contact with an infected person through respiratory droplets. Whether a pregnant woman with COVID-19 can transmit the virus that causes COVID-19 to her fetus or neonate by other routes of vertical transmission (before, during, or after delivery) is still unknown.
9. What is the risk of my child becoming sick with COVID-19?
Based on available evidence, children do not appear to be at higher risk for COVID-19 than adults. While some children and infants have been sick with COVID-19, adults make up most of the known cases to date. You can learn more about who is most at risk for health problems if they have COVID-19 infection on CDC’s current Risk Assessment page.
10. Are the symptoms of COVID-19 different in children than in adults?
No. The symptoms of COVID-19 are similar in children and adults. However, children with confirmed COVID-19 have generally presented with mild symptoms. Reported symptoms in children include cold-like symptoms, such as fever, runny nose, and cough. Vomiting and diarrhea have also been reported. It’s not known yet whether some children may be at higher risk for severe illness, for example, children with underlying medical conditions and special healthcare needs. There is much more to be learned about how the disease impacts children.
11. Should I worry about COVID-19?
Illness due to COVID-19 infection is generally mild, especially for children and young adults. However, it can cause serious illness: about 1 in every 5 people who catch it need hospital care. It is therefore quite normal for people to worry about how the COVID-19 outbreak will affect them and their loved ones.
We can channel our concerns into actions to protect ourselves, our loved ones and our communities. First and foremost, among these actions is regular and thorough hand-washing and good respiratory hygiene. Secondly, keep informed and follow the advice of the local health authorities including any restrictions put in place on travel, movement and gatherings.
12. Who is at risk of developing severe illness?
While we are still learning about how COVID-2019 affects people, older persons and persons with pre-existing medical conditions (such as high blood pressure, heart disease, lung disease, cancer or diabetes) appear to develop serious illness more often than others.
13. Are antibiotics effective in preventing or treating COVID-19?
While we are still learning about how COVID-2019 affects people, older persons and persons with pre-existing medical conditions (such as high blood pressure, heart disease, lung disease, cancer or diabetes) appear to develop serious illness more often than others.
14. Are there any medicines or therapies that can prevent or cure COVID-19?
While some western, traditional or home remedies may provide comfort and alleviate symptoms of COVID-19, there is no evidence that current medicine can 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 that include both western and traditional medicines.
15. Is there a vaccine, drug or treatment for COVID-19?
Not yet. To date, there is no vaccine and no specific antiviral medicine to prevent or treat COVID-2019. However, those affected should receive care to relieve symptoms. People with serious illness should be hospitalized. Most patients recover thanks to supportive care.
Possible vaccines and some specific drug treatments are under investigation. They are being tested through clinical trials. WHO is coordinating efforts to develop vaccines and medicines to prevent and treat COVID-19.
The most effective ways to protect yourself and others against COVID-19 are to frequently clean your hands, cover your cough with the bend of elbow or tissue, and maintain a distance of at least 1 meter (3 feet) from people who are coughing or sneezing.
16. Should I wear a mask to protect myself from catching the COVID-19 virus?
Only wear a mask if you are ill with COVID-19 symptoms (especially coughing) or looking after someone who may have COVID-19. Disposable face mask can only be used once. If you are not ill or looking after someone who is ill then you are wasting a mask. There is a world-wide shortage of masks, so WHO urges people to use masks wisely.
WHO advises rational use of medical masks to avoid unnecessary wastage of precious resources and mis-use of masks.
The most effective ways to protect yourself and others against COVID-19 are to frequently clean your hands, cover your cough with the bend of elbow or tissue and maintain a distance of at least 1 meter (3 feet) from people who are coughing or sneezing.
17. Until when should I wear a mask after recovering from an illness with respiratory symptoms?
In order to avoid infecting others, you should use a mask for as long as you are still coughing or sneezing. You should only stop after a complete recovery (which means 24-48 hours after having no symptoms without medication).
18. I am looking after someone who is ill with suspect or confirmed COVID-19. What precautions should I take?
- You should limit the movement around the house of the individual who is ill and minimize shared space.
- Ensure shared spaces like bathrooms, and the kitchen are well ventilated. One way to do this is by keeping the windows open. Clean and disinfect the bathroom and toilet surface at least once a day using regular household soap or detergent for cleaning and then disinfecting with a regular household disinfectant containing 0.5% sodium hypochlorite.
- Do not forget the importance of hand hygiene with alcohol-based hand-rub or soap and water (if hands are visibly soiled).
- Whenever possible, household members should stay in a different room or maintain a distance of at least 1 meter from the ill person.
- When helping care for the sick individual, wear a tightly fitted medical/surgical mask that covers your nose and mouth when in the same room as the affected individual. Make sure you are careful not to touch your mask. If your mask gets wet or dirty, it should be replaced. When removing a mask, it is important to throw it away and perform hand hygiene. Dispose of any material with respiratory secretions immediately after use.
- Both the ill individual and you, as the caregiver, should perform hand hygiene after contact with respiratory secretions.
19. How long is the incubation and transmission period for COVID-19?
The “incubation period” means the time between catching the virus and beginning to have symptoms of the disease. Most estimates of the incubation period for COVID-19 range from 1- 14 days, most commonly around five days.
20. Can humans become infected with the COVID-19 from an animal source?
Possible animal sources of COVID-19 have not yet been confirmed. To protect yourself, such as when visiting live animal markets, avoid direct contact with animals and surfaces in contact with animals. Ensure good food safety practices at all times. Handle raw meat, milk or animal organs with care to avoid contamination of uncooked foods and avoid consuming raw or undercooked animal products.
21. How long does the virus survive on surfaces?
It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems to behave like other coronaviruses. Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g. type of surface, temperature or humidity of the environment).
If you think a surface may be infected, clean it with simple disinfectant to kill the virus and protect yourself and others. Clean your hands with an alcohol-based hand rub or wash them with soap and water. Avoid touching your eyes, mouth, or nose.
22. How can I get tested for COVID-19?
If you are well, no testing is recommended. If you are experiencing symptoms of COVID-19, you should immediately isolate yourself from others. Call your local clinic/medical facility to inform them of your condition and relevant travel/exposure history. If you had been identified as a close contact of a case by the local Ministry of Health or WHO, please also indicate this. From here you will be advised if a medical assessment is necessary and how to get tested.
23. What alternatives do I have if there are no hand sanitizers available?
Can I use other alcohol like ethyl or liquor? If hand sanitizers are not available, hand washing with soap and water is the recommended, and even better, alternative. Liquor is not effective against coronavirus. For an alcohol-based hand rub to be effective, it must have an alcohol content of 60% to 95%.
24. Can people who recover from COVID-19 be infected again?
We know that for similar coronaviruses, infected people are unlikely to be re-infected shortly after they recover. However, because the immune response to COVID-19 is not yet understood, it is not yet known whether similar immune protection will be observed for patients who have recovered from COVID-19.
25. Is it safe to receive a package from an area where COVID-19 has been reported?
Yes. The likelihood of an infected person contaminating commercial goods is low and the risk of catching the virus that causes COVID-19 from a package that has been moved, travelled, and exposed to different conditions and temperature is also low.
26. Is there a connection between COVID -19 and environment temperature?
It is not known yet if weather and temperature changes impact or has any connection with COVID-19. At this time, it is not clear or known if the spread of COVID-19 will decrease when the weather becomes warmer.
27. Can I catch the virus from being in an enclosed space (i.e. bus, subway) in close proximity to someone who doesn’t have respiratory symptoms?
Since the virus is transmitted through respiratory droplets, the risk of catching it from somebody who is asymptomatic, even a contact of a confirmed COVID-19 case, is low. However, in light of the pandemic, everyone should maintain social distancing, which means keeping at least 1 meter away from others, avoiding mass gatherings and areas with large numbers of people, and practicing frequent hand washing and hand sanitizing according to the recommendation.
28. Should I start avoiding people of Asian descent and their businesses?
The virus can affect anyone regardless of nationality, race and color. The Organization will not tolerate discrimination and encourages everyone to promote culturally appropriate and empathetic community engagement and to detect and rapidly respond to negative public perceptions and counter misinformation.
29. When should we identify ourselves as "being sick" and stay at home?
Although a fever is a sure sign that you are sick enough not to come to work, anyone experiencing respiratory symptoms like coughing and sneezing should stay at home.
