Because a bunch of these patients are people with suspected, not confirmed, covid-19 and so they're treating pneumonia which they think is probably bacterial but possibly viral.

Also, they were thinking that covid-19 in already vulnerable people was damaging the lungs and making bacterial pneumonia much more likely, so they were treating preventatively.

Droplets in the air are one route of transmission, but there are others. It's likely that most people are not infected via this route, but via fomites. Infected people cough onto a surface, and later someone touches that surface and then their face.

And then what? How does the virus get from their face into the lungs in enough quantity to infect them?

They touch their mouth, or eyes, or nose.

They're already infected. I don't understand the question. Are you asking how the virus replicates? It's a strand of RNA that takes over human cell replication. It binds to ACE2, which is how it targets lungs. https://blogs.plos.org/dnascience/2020/02/20/covid-19-vaccin...

People touch their face all day everyday, even when they've been told not to. Even when they're telling other people to stop doing it. https://twitter.com/Kojoanan/status/1235275598697771011

It's unusual for people in public places to be coughed on. I can't think of it happening to me in the past 5 years.

Healthcare professionals wear masks (and goggles, and protective clothing, and sometimes gloves) because their work involves close contact with ill people who are coughing over them.
