The authors “have great potential for inhalation exposure of fine respiratory droplets (microdroplets) to the virus at short to medium distances (up to a few meters, or up to room scale).
The World Health Organization (WHO) has reported aerial transmission of the virus after the study was published. May It is involved in infection, especially in poorly ventilated rooms and buildings, but does not declare aerosols as the definitive cause.
