Denial exists even among the medical profession. The story of AIDS is a sociological story about misfits. Nobody wants the stigma, so people pretend that they don't know why people are dying. The victims don't cry out. Doctors and obituaries do not give the killer its name.
Families recoil in shame.
Often the religious communities cluck about people getting from God what they deserve. Most do not know how or when they caught the virus, many never know they have it. Pharmaceutical Companies and Social Time Bombs Drug companies have tried to protect their enormous profits and monopolies while Africans die. Even at new reduced prices, the cost of AIDS drugs exceeds the ability of poor countries to pay, and the cost of the clinics and training necessary to deliver the drugs makes the challenge even tougher. Less than one percent of Africans have access to the drugs that can prolong their lives and stem transmission.
