That is true. Negroes do hunt and eat other primates in Africa. Consequently, the killing, butchering and consumption of these chimps could be one method of disease travel.

On the other hand, we have read stories here about black African males having sex with goats. And I've also followed stories about African blacks having sex with dogs. If they'll have sex with dogs and goats, why wouldn't they have sex with chimps? Chimpanzees more closely approximate negroe anatomy and behavior than dogs or goats. There is also a certain simian look to blacks that no honest man can deny. So I wouldn't be too hasty to rule out bestiality as another possible method of disease travel.
