But if you are correct - then it's a compelling reason or companies to encourage as many people as possible to work from home. I was in a Walmart this evening and the cashier coughed and wiped her mouth with her hand. Classy. I took my items to the self-checkout which had just been wiped down with some ammonia smelling concoction.

No. If it is aerosolized, all they have to do is exhale and they fill a small room with 100s of millions virus'
