Asked on Facebook crosspost: If it’s transmitted by cough, how do asymptomatic people transmit it? Is it dependent on other diseases or allergies to provoke coughing?
None of the studies cited address the question of how presymptomatic transmission occurs, but my guess is that it’s the same: respiratory droplets. People also emit droplets when they talk and breathe. There aren’t as many and they don’t travel as far as when they cough, but they’re there.

So I guess if you’re close enough to smell someone’s bad breath, you’re close enough to catch their COVID-19...?
