As the coronavirus continues to make the news, a host of untruths has surrounded the topic. In this special article, I address some of these myth and conspiracies busted by WHO.
A novel coronavirus is a new strain of coronavirus that has not been previously identified in humans.
Coronaviruses (CoV) are a large family of viruses transmitting between animals and people that cause illness ranging from the common cold to more severe diseases such as the Middle East respiratory syndrome (MERS-CoV) and severe acute respiratory syndrome (SARS-CoV).

Myth 01: You can catch COVID-19, no matter how sunny or hot the weather is
Countries with hot weather have reported cases of COVID-19. To protect yourself, make sure you clean your hands frequently and thoroughly and avoid touching your eyes, mouth, and nose.
Exposing yourself to the sun or to temperatures higher than 25 degrees DOES NOT prevent the coronavirus disease (COVID-19).
Myth 02: Catching the new coronavirus DOES NOT mean you will have it for life.
Most of the people who catch COVID-19 can recover and eliminate the virus from their bodies. If you catch the disease, make sure you treat your symptoms. If you have cough, fever, and difficulty breathing, seek medical care early – but call your health facility by telephone first. Most patients recover thanks to supportive care.
Myth 03: Being able to hold your breath for 10 seconds or more without coughing or feeling discomfort DOES NOT mean you are free from the coronavirus disease (COVID-19) or any other lung disease.
The most common symptoms of COVID-19 are dry cough, tiredness, and fever. Some people may develop more severe forms of the disease, such as pneumonia. The best way to confirm if you have the virus-producing COVID-19 disease is with a laboratory test. You cannot confirm it with this breathing exercise, which can even be dangerous.
Myth 04: Drinking alcohol does not protect you against COVID-19
Frequent or excessive alcohol consumption can increase your risk of health problems.
Myth 05: COVID-19 virus can not be transmitted in areas with hot and humid climates
From the evidence so far, the COVID-19 virus can be transmitted in ALL AREAS, including areas with hot and humid weather. Regardless of climate, adopt protective measures if you live in, or travel to an area reporting COVID-19. The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose.
Myth 06: Cold weather and snow CAN kill the new coronavirus.
There is no reason to believe that cold weather can kill the new coronavirus or other diseases. The normal human body temperature remains around 36.5°C to 37°C, regardless of the external temperature or weather. The most effective way to protect yourself against the new coronavirus is by frequently cleaning your hands with alcohol-based hand rub or washing them with soap and water.
Myth 07: Taking a hot bath to prevent the new coronavirus disease
Taking a hot bath will not prevent you from catching COVID-19. Your normal body temperature remains around 36.5°C to 37°C, regardless of the temperature of your bath or shower. Actually, taking a hot bath with extremely hot water can be harmful, as it can burn you. The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose.
08: The new coronavirus CAN be transmitted through mosquito bites.
To date there has been no information nor evidence to suggest that the new coronavirus could be transmitted by mosquitoes. The new coronavirus is a respiratory virus which spreads primarily through droplets generated when an infected person coughs or sneezes, or through droplets of saliva or discharge from the nose. To protect yourself, clean your hands frequently with an alcohol-based hand rub or wash them with soap and water. Also, avoid close contact with anyone who is coughing and sneezing.
09: Hand dryers effective in killing the new coronavirus
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.
10: Ultraviolet disinfection lamp kills the new coronavirus
UV lamps should not be used to sterilize hands or other areas of skin as UV radiation can cause skin irritation.
11: Thermal scanners are effective in detecting people infected with the new coronavirus
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 a fever. This is because it takes between 2 and 10 days before people who are infected become sick and develop a fever.
12: Spraying alcohol or chlorine all over your body kill the new coronavirus
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.
13: Vaccines against pneumonia protect you against the new 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.
14: Regularly rinsing your nose with saline help prevent infection with the new 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.
Myth 15: Eating garlic helps prevent infection with the new 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.
16: The new coronavirus affect older people only
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.
17: Antibiotics effective in preventing and treating the new 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.
18: Are there any specific medicines to prevent or treat the new 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.
