There’s a heap of myths about COVID-19 doing the rounds, from the somewhat believable to the downright wacky. Here’s some common ones busted.

Why This Matters: Accurate and relevant information will help us control the spread of the COVID-19 virus.




From worries about pets spreading the virus that causes COVID-19, to eating garlic to ward off an infection, there’s a range of questions and myths spreading across the internet.


The World Health Organisation has produced these neat infographics and videos to tackle some of the most common questions and myths – so even if you’re not sucked in by them, have a read next time you see a well-meaning but misguided post.

Does the new coronavirus affect older people, or are younger people also susceptible?


older or younger people affected by COVID-19 coronavirus


People of all ages can be infected by the new coronavirus (2019-nCoV). Older people, and people with pre-existing medical conditions (such as asthma, diabetes, heart disease) appear to be more vulnerable to becoming severely ill with the virus.


WHO advises people of all ages to take steps to protect themselves from the virus, for example by following good hand hygiene and good respiratory hygiene.




Deeper: What we know (and don’t know) about the COVID-19 virus




Do I need to wear a mask?




If you are healthy, you only need to wear a mask if you are taking care of a person with suspected COVID-19 virus infection.


Wear a mask if you are coughing or sneezing.


Masks are effective only when used in combination with frequent hand-cleaning with alcohol-based hand rub or soap and water.


If you wear a mask, then you must know how to use it and dispose of it properly.

Will a mask protect me from getting infected?




Before putting on a mask, clean hands with alcohol-based hand rub or soap and water.


Cover mouth and nose with mask and make sure there are no gaps between your face and the mask.


Avoid touching the mask while using it; if you do, clean your hands with alcohol-based hand rub or soap and water.


Replace the mask with a new one as soon as it is damp and do not re-use single-use masks.


To remove the mask: remove it from behind (do not touch the front of mask); discard immediately in a closed bin; clean hands with alcohol-based hand rub or soap and water.


Are antibiotics effective in preventing and treating the new coronavirus?


antibiotics don't kill coronavirus


No, antibiotics do not work against viruses, only bacteria.


The new coronavirus (2019-nCoV) is a virus and, therefore, antibiotics should not be used as a means of prevention or treatment.


However, if you are hospitalized for the 2019-nCoV, you may receive antibiotics because bacterial co-infection is possible.


Are hand dryers effective in killing the new coronavirus?


Coronavirus not killed by hand dryers


No. Hand dryers are not effective in killing the 2019-nCoV. To protect yourself against the new coronavirus, you should frequently clean your hands with an alcohol-based hand rub or wash them with soap and water. Once your hands are cleaned, you should dry them thoroughly by using paper towels or a warm air dryer.


Can an ultraviolet disinfection lamp kill the new coronavirus?


UV light can kill coronavirus but you dont want to


UV lamps should not be used to sterilize hands or other areas of skin as UV radiation can cause skin irritation.




Deeper: What the Wuhan coronavirus does to make people severely ill




How effective are thermal scanners in detecting people infected with the new coronavirus?


COVID-19 thermal scans


Thermal scanners are effective in detecting people who have developed a fever (i.e. have a higher than normal body temperature) because of infection with the new coronavirus.


However, they cannot detect people who are infected but are not yet sick with fever. This is because it takes between 2 and 10 days before people who are infected become sick and develop a fever.


Are there any specific medicines to prevent or treat the new coronavirus?


medical treatments for COVID-19 coronavirus


To date, there is no specific medicine recommended to prevent or treat the new coronavirus (2019-nCoV).


However, those infected with the virus should receive appropriate care to relieve and treat symptoms, and those with severe illness should receive optimized supportive care. Some specific treatments are under investigation, and will be tested through clinical trials. WHO is helping to accelerate research and development efforts with a range or partners.


Can spraying alcohol or chlorine all over your body kill the new coronavirus?


COVID-19 coronavirus alcohol and chlorine


No. Spraying alcohol or chlorine all over your body will not kill viruses that have already entered your body. Spraying such substances can be harmful to clothes or mucous membranes (i.e. eyes, mouth). Be aware that both alcohol and chlorine can be useful to disinfect surfaces, but they need to be used under appropriate recommendations.


Is it safe to receive a letter or a package from China?


COVID-19 Coronavirus packages from China


Yes, it is safe. People receiving packages from China are not at risk of contracting the new coronavirus. From previous analysis, we know coronaviruses do not survive long on objects, such as letters or packages.


Can pets at home spread the COVID-19 coronavirus?


Coronavirus and pets


At present, there is no evidence that companion animals/pets such as dogs or cats can spread the new coronavirus. However, it is always a good idea to wash your hands with soap and water after contact with pets. This protects you against various common bacteria such as E.coli and Salmonella that can pass between pets and humans.


There has been one reported case of a dog with a “low-grade” infection in Hong Kong. However there is still no evidence that pets can spread the virus, nor become ill themselves.


Do vaccines against pneumonia protect you against the new coronavirus?


pneumonia vaccines and COVID-19 coronavirus


No. Vaccines against pneumonia, such as pneumococcal vaccine and Haemophilus influenza type B (Hib) vaccine, do not provide protection against the new coronavirus.


The virus is so new and different that it needs its own vaccine. Researchers are trying to develop a vaccine against 2019-nCoV, and WHO is supporting their efforts.


Although these vaccines are not effective against 2019-nCoV, vaccination against respiratory illnesses is highly recommended to protect your health.


Can regularly rinsing your nose with saline help prevent infection with the new coronavirus?


rinsing nose with saline doesn't protect from COVID-19 coronavirus


No. There is no evidence that regularly rinsing the nose with saline has protected people from infection with the new coronavirus.


There is some limited evidence that regularly rinsing nose with saline can help people recover more quickly from the common cold. However, regularly rinsing the nose has not been shown to prevent respiratory infections.


Can eating garlic help prevent infection with the new coronavirus?


garlic doesn't protect from coronavirus


Garlic is a healthy food that may have some antimicrobial properties. However, there is no evidence from the current outbreak that eating garlic has protected people from the new coronavirus.
