In an open letter to be published in the New York Times, 239 researchers call on the WHO to reconsider its recommendations against the virus.
The hypothesis about the transmission of the coronavirus by air is back on the scene. In an open letter to be published in the New York Times, 239 researchers from 32 countries warn the World Health Organization (WHO) about airborne transmission of the coronavirus.
In addition to the transmission of the virus through large droplets emitted by sneezing, contamination through light aerosols, floating in the air and capable of traversing the room, would also be possible.
closed, poorly ventilated high-risk area
According to the WHO, the coronavirus is mainly transmitted by large droplets that fall rapidly to the ground due to their weight. This does not fit the strict definition of an airborne virus. For the authors of the letter, the virus will also spread through smaller droplets that form as we speak. In fact, they are asking the WHO to revise its recommendations and put more emphasis on this mode of transmission.

However, researchers are ruling out the infectious potential of these fine droplets. The risk would be especially in closed spaces and poorly ventilated areas, where people are in close contact for a long time.

However, this hypothesis defended by the researchers is in the background of the importance of wearing a mask in a closed environment. In addition, it also emphasizes the key role of ventilation indoors, in limiting the risk of spreading the virus.
