Whether it is through large droplets that fly through the air after a sneeze, or much smaller exhaled droplets, the experts say Covid-19 is borne through air and can infect people when inhaled.
In an open letter to the World Health Organization (WHO), 239 scientists from 32 countries have claimed that the novel coronavirus is airborne and have called for the global health body to revise its recommendations, the New York Times reported.
The WHO has been saying that the coronavirus or Covid-19 is spread primarily by large respiratory droplets that when expelled by infected people through coughs and sneezes, fall on surface. Thus, the WHO has been recommending hand washing as a primary prevention strategy as our hands may come in contact with such surfaces.
In its latest update on June 29, the WHO said the transmission of the virus through air is possible only during medical procedures that produce aerosols, or droplets smaller than 5 microns. Such procedures include tracheal intubation, non-invasive ventilation, and tracheotomy among others and only healthcare workers are exposed to such risk, according to the WHO.
