WHO: Airborne transmission of COVID-19 possible in closed spaces
The World Health Organization (WHO) asserted in its new guidance, Thursday (July 9), that the possibility of acquiring coronavirus through air particles cannot be prevented especially in closed indoor spaces.
In the new guidance, the WHO acknowledged some research suggesting that the virus may become airborne in crowded places including restaurants and gyms.
"In these events, short-range aerosol transmission, particularly in specific indoor locations, such as crowded and inadequately ventilated spaces over a prolonged period of time with infected persons cannot be ruled out," the WHO said in its new guidance.
According to the agency, airborne transmission of the coronavirus could be possible if virus-carrying droplets "generate microscopic aerosols" by evaporating, or if "normal breathing and talking results in exhaled aerosols." Theoretically, someone could inhale the aerosols and become infected.
However, the WHO emphasized, that more research is needed to further investigate and prove that the virus can be transmitted through air particles. As of the moment, the main mode of transmission is still believed to be through respiratory droplets.
