The thing is, though, Covid-19 doesn't cause coughing in asymptomatic cases.

I had no cough before developing fever and muscle pains, and only a very mild cough afterwards. Are you suggesting that asymptomatic cases are not infectious?

Likewise, according to the article, "nobody there was coughing or sneezing".

Talking and singing produce respiratory droplets and aerosols. See https://www.lesswrong.com/posts/Jnq2A7A7ytgttQ5Ek/covid-tran... and the references cited therein.

You ever breathe out on a cold winter day? Your breath is humid.

Exactly! But I wouldn't describe this humidity as "droplets", like you would produce from coughing or sneezing.

I might not describe it that way either, but do medical professionals describe it that way?

It's not just large droplets that seem to carry the virus but also aerosolized droplets that travel farther when you cough or sneeze and that are emitted from talking and singing.

Yes, exactly my point.
