Thank you for your comments and questions that I will attempt to answer.
1. The hiv test is probably picking up random proteins that are in the blood. As no hiv virus has been isolated, the test cannot detect something called hiv.
2. What do you mean when you say, "falling ill with AIDS"? AIDS is the collective term for 29 diseases so which one are you talking about? In Africa tuberculosis gives the highest death rate. So a thin, coughing man shows up. If the bogus test is negative, he has TB. If it is positive he has AIDS. People have suffered from TB for centuries before the term AIDS came into existence. The tragedy is that the African man will receive the right treatment with a diagnosis of TB and the wrong treatment with a diagnosis of AIDS.
3. Take a look at the picture that I hope you get from this link:
These people have AIDS. Their immune systems have collapsed. They are Nazi concentration camp survivors in 1945. Starvation is the commonest cause of AIDS so its been around for a long time.
I would need references in order to answer your questions under the rest of 3. I don't know what a baby born with AIDS is? I suspect they mean a baby with a positive test and that is meaningless on its own. What symptoms is the baby expressing?
