A group of 239 scientists from 32 different countries have published an open letter to the World Health Organization and other health agencies, calling for them to update their information on the coronavirus.
In an article entitled “It is Time to Address Airborne Transmission of COVID-19,” the group of scientists argue that the WHO needs to give more weight to the role of the airborne spread of Covid-19. The New York Times first reported the news on Saturday.
“There is significant potential for inhalation exposure to viruses in microscopic respiratory droplets (microdroplets) at short to medium distances (up to several meters, or room scale), and we are advocating for the use of preventive measures to mitigate this route of airborne transmission,” the scientists wrote in the paper.
It appears to contradict previous evidence that the virus is transmitted from person to person via droplets from the nose or mouth. These are expelled when a person with the infection coughs, sneezes or speaks.
