WHO underplaying risk of airborne spread of Covid 19 says scientists.

An open letter to be published later this week, 239 scientists and researchers are warning the WHO that they are underplaying the probability that the coronavirus can be spread after lingering in the air.

It has been thought that the virus was spreading primarily through respiratory droplets being inhaled by others and direct contact with an infected person. But the scientists are saying that transmission via aerosol appears to be playing a greater role in the pandemic than previously believed. reported The Guardian.
