Like measles? Smallpox? They are respiratory viruses too
Yet we don't lock down at the first sign of a measles outbreak. Where I'm from almost everyone got vaccinated and a lot of kids had it anyway. The one big difference is that an infection seems to convey pretty much lifelong protection.
Smallpox is a different thing, very serious but not so contagious so it was easy to stamp out.

From Measles? Because COVID-19 infection certainly does not confer lifelong protection! That's real east to look up!
