I'm not sure we (that is, humans) realized that SIV was a thing until HIV prompted us to look in those places. It's the classic example of not knowing what to look for until you've found it.

- RyanZAG 11y agoYou'd probably be wrong about that. Even today in most of these places, a captive animal that dies is just 'sick' and disposed of. Or often sold off as food if the death symptoms aren't obviously apparent, as would be the case with HIV. There is no functioning FDA in central africa.
