HIV skeptics take on conventional wisdom

July 23 marks the final day of an international AIDS conference where scientists from around the world have worked to fight and cure the disease. At the same time some continue to challenge the conventional wisdom about AIDS.

The international conference is focused on a viral or pathogenic cause to AIDS, said Robert Scott Bell, a radio host and homeopath. He argued that those at the conference discount the possibility of a drug or toxicological cause, such as the use of western pharmaceuticals.
