Your suggestion of staying home if sick is one I agree with. Unfortunately I cannot make others do this. In fact, where I live in the USA I come across people who are visibly/audibly ill in my daily life: air travel, public transport, grocery store, and so on. I would prefer if these people stayed home, but can I make them? I can wear a mask, and I do (typically N95 in public places). If others think I look crazy, that is a small price to pay to avoid a few weeks of being sick or infecting someone else. Particularly my vulnerable family members.
