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

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-vaccine-will-close-in-on-the-spikes/ 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 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.
