If this virus can stay in the air for up to 3 hours.  
How do you plan not to breath the air around you?  

I know I didn't want to talk about this. But what else is there to talk about?

I will evolve fish gills and go underwater .  

If it is, my understanding is that the potential for "airborne" transmission, as opposed to droplets, is extremely low for the general public. Medical workers might be facing concentrations in the air that could be a reasonable transmission vector.

If you were a bit less serious I'll say just perform your local area analysis. If you are at least 6" taller than 99% of the infected people, and there is no troubling up draft, you have nothing to fear but fear itself
