Why do some websites say that HIV doesn’t cause AIDS in Africa, and that it’s caused by malnutrition or dirty water?
tiny minority of scientists dispute the theory that HIV causes AIDS, and some have suggested various non-infectious causes. These theories have gained a certain amount of popularity on the Internet. However, the vast majority of scientists agree that the evidence that HIV causes AIDS is abundant and conclusive. Numerous studies in Africa and elsewhere have shown that HIV infection is the only factor that predicts who will develop AIDS, and that AIDS does not occur without HIV.
