Lol. Here is a study done of viruses found in Apes & monkeys hunted for bushmeat in Africa: it is highly concerning, considering the sheer number of viruses circulating in the ape & monkey populations in Africa.
How humans acquired the ape precursors of HIV-1 groups M, N, O, and P is not known; however, based on the biology of these viruses, transmission must have occurred through cutaneous or mucous membrane exposure to infected ape blood and/or body fluids. Such exposures occur most commonly in the context of bushmeat hunting (Peeters et al. 2002). Whatever the circumstances, it seems clear that human–ape encounters in west central Africa have resulted in four independent cross-species transmission events. Molecular clock analyses have dated the onset of the group M and O epidemics to the beginning of the twentieth century..."

Makes you wonder what other nasty viruses have already made the leap to people & are currently circulating in the populations in those areas if HIV had circulated for 70 years over there before becoming a pandemic.
