The WHO South-East Asia office said that the novel coronavirus doesn’t spread airborne. However, there has been a reported possibility of aerosol transmission in a relatively closed environment with prolonged exposure.
The statement released by the WHO office says: “Airborne spread hasn’t been reported for COVID-19. Chinese authorities reported the possibility of aerosol transmission in a relatively closed environment with prolonged exposure like ICUs-CCUs in hospitals, but more data analysis is needed to understand this.”
“Airborne spread has not been reported for COVID-19. Based on the information received so far and on our experience with other coronaviruses, COVID-19 appears to mostly spread through respiratory droplets (for instance when a sick person coughs) and close contact.
