Can the coronavirus spread through the air?

While airborne transmission seems possible, there are some relatively straightforward precautions you can take to reduce your risk.

We still don't know exactly how many particles of virus you need to come into contact with to get infected with COVID-19, and detecting miniscule particles floating in the air is notoriously difficult, so hard data on airborne transmission is sparse.

But there's evidence to show this is possible, particularly indoors.

The physical distancing measures most of us are already observing are a great start.

Staying home as much as possible, avoiding crowded areas and standing a bit further away from the people you do come into contact with all reduce the likelihood that you'll be sharing space with someone who's infected.

Good ventilation lowers risk

Good ventilation for enclosed spaces reduces the chances of the virus hanging around in the air.

Bringing fresh air into an enclosed space dilutes the number of viral particles in the air, scaling down the risk of you coming in contact with enough to infect you.

Keeping at least 2 meters apart
The fact that we're told to keep a distance apart from each other implies that it can travel through the air. How long it can stay in the air depends on the respiratory droplet size, air flow, humidity and other factors. Research is still ongoing.
