> The primary way to spread a virus via droplet transmissions is to spend a sustained amount of time around lots of other people in an indoor space

In some ways, very similar to TB, although a much shorter exposure time is sufficient for transmission.

Who'd have thought that two diseases that mostly infect the lungs might have similar transmission routes...

I'm sure you think that's clever but there are plenty of respiratory diseases that don't require sustained contact.

Measles, for example.

The point is sustained contact, not the route of transmission.
