> but I read that viruses with a high mortality rate are much easier to contain Only if all other parameters remain the same. There could be much worse viruses than SARS-Cov-2 (e.g. that are similar in eventual mortality but have symptoms lag behind start of shedding even more). A virus could be just as species-ending as a large rock hitting the earth, they are just both very unlikely or else we wouldn't be here.
