And yet, only in 2019 it jumped from animal to humans. There were other human coronaviruses before of course. But as far as we can tell, this specific one did not make the jump in all the years before. The reason is, as with all zoonoses, it takes close proximity to the animal, lucky mutations, and conditions for subsequent spreading to turn into a pandemic. Pandemics are not at all inevitable. My point is we are inadvertently creating the conditions that allow diseases like this to spread in the first place.
