(In) Africa ... HIV/AIDS ... is spread mostly through heterosexual sex.

Well, maybe healthly females get contract it this way. I do not believe that healthy heterosexual males contract it engaging in "normal heterosexual" sex with females. They do contract it from infected females if they have genital lesions or sores from other venereal diseases which are also endemic in Africa.

Right, that is the point regarding sores and stuff. If China is getting it like Africa, outside of homosexual contact and drug needles, the sores on the body make a big infectious hit on the population.

I've read several articles about bad hygiene in Africa and sores being on men and hookers who spread the disease.
