It always has been. The virus is aerosolized through exhalation, and spreads much like secondhand smoke [0].

- throwitaway1235 6y agoI remember a listening to a podcast interviewing a physician from a major hospital who made sure to explain the difference between an airborne pathogen and one that is respiratory active. Jogging my memory. Airborne meaning a virus that a person exhales in an elevator (example) will still be present and transmissible x amount of time later. Respiratory active meaning transmissible by coughing/exhaling in the presence of someone else. These are important distinctions if true and still relevant.
- Exmoor 6y agoIn the sense of your explanation it COVID-19 is indeed airborne.
- jobigoud 6y agoAs far as I understand it lives in droplets heavier than air that fall to the ground in a matter of a few seconds. The next person entering the elevator won't breathe it. Truly airborne viruses can be lifted by regular air turbulences and travel kilometers before landing on someone else.
- rweir 6y agonope, obviously that's a continuum but it's been found to be much further towards the airborne end than was originally generally thought: [here](https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(20)30514-2/fulltext#:~:text=On%20Oct%205%2C%202020%2C%20the,the%20virus%20under%20certain%20circumstances https://www.thelancet.com/journals/lanres/article/PIIS2213-2....)
