I'm not sure that your first sentence is true. The symptomatic effect that a not-mild virus strain has can help it spread, for obvious reasons. It seems like there's an optimization problem there, with a sweet spot where the virus doesn't kill its host, but makes them cough and sneeze to spread to other hosts.
