Coronavirus spreads around the world along with false information on social media. Since the start of the epidemic, the World Health Organization (WHO) identifies and responds to received ideas. Rumors, eccentric remedies … We take stock.
The virus is spread by mosquito bites
FALSE. Covid-19 is a respiratory virus. This means that it is transmitted by air, with the postillions evacuated during a sneeze or a cough, and by direct contact with the face, nose and mouth. “To date, there is no information or evidence to suggest that the coronavirus could be transmitted by mosquitoes,” said the World Health Organization.
The cold can kill the virus
FALSE. Whatever the outside temperature, body temperature remains around 37 degrees. Therefore, “there is no reason to believe that cold weather can kill the new coronavirus or other pathogens,” according to the WHO.
The virus can be spread by things like banknotes
TRUE, but … the risk is very low. Mid February, the Chinese central bank had announced that it was disinfecting and quarantining the banknotes to limit the spread of the virus.
An object can actually be contaminated when a person coughs or sneezes. Nevertheless, the WHO explains that “the coronavirus can survive on surfaces for a few hours or more”. By washing your hands regularly with soap or an alcoholic gel, the risk of being infected by touching coins, banknotes or credit cards, for example, is therefore very low.
Likewise, receiving a package or letter from a risk zone, such as China or Italy, poses no risk.
Masks can be sterilized and reused
FALSE. The protective masks for the face, which make it possible not to spread the disease, are for single use. They should be changed every four hours or after close contact with an infected person.
Spraying alcohol or chlorine on the body kills the virus
FALSE. It will not kill the virus that has already entered the body. Furthermore, it can be harmful if it comes in contact with the eyes or mouth. On the other hand, alcohol and chlorine can disinfect surfaces, of course respecting the recommendations.
Antibiotics are effective in curing coronavirus
FALSE. It’s well known, antibiotics only work against bacteria, not viruses. They cannot be used as a means of prevention or treatment in the case of Covid-19.
Pneumonia vaccines protect against Covid-19
FALSE. This coronavirus is so new and unknown that it requires its own vaccine. Researchers from all over the world are still working on its development.
Saline solutions in the nose can prevent infection
FALSE. Rinsing your nose with saline is often used to recover quickly from a common cold. On the other hand, the WHO indicates that “it has not been shown that regular rinsing of the nose can prevent respiratory infections”.
