(M+D Archive) Coronaviruses
This is not the first Coronavirus rodeo. The family of viruses from which the current 2019 novel Coronavirus sprang has several endemic, non-threatening variants, and two very, very big siblings, SARS and MERS. So while you should probably take any government assurance that there's no trouble and everything is ok with a pinch of salt (or in the case of a totalitarian government, a whole mine full of the stuff), Coronaviruses themselves aren't as scary as they look right now. Mostly.
