"There has been no proof of that as far as COVID-19 is concerned.". For both forms of COVID-19 disease transmission – close contact and airborne – it’s respiratory droplets containing the virus that spread illness. It’s able to travel only a short distance before gravitational forces pull it down. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. The updated advisory comes after the public health agency previously published, then retracted, guidance acknowledging the potential for such exposure. In droplet form, the coronavirus is airborne for a few seconds after someone sneezes or coughs. Through respiratory droplets produced when an infected person coughs, sneezes, or talks.
