Did the WHO get it wrong so far?The World Health Organization (WHO) had previously believed that the coronavirus spread through droplets fired by a cough or a sneeze, and could travel up to 2 metres.
Since droplets are heavy, and cannot stay airborne for long, the risk of transmission was more from touching infected surfaces.However, experts now believe the virus can spread through aerosols.
An aerosol is made up of smaller, respiratory particles that get released when one speaks or breathes. These are lighter and can stay airborne for far longer, and therefore can carry the virus to longer distances, potentially beyond 2 metres.What does this development mean?Since the virus can travel more than the previously believed 2 metres (6 feet),.
