Difficulty in Isolating HIV from Sick Patients
Finding HIV in sick people is very difficult. Unlike, say measles, where the disease agent can easily be isolated from the blood and identified, performing the same task with HIV has proven extraordinarily difficult, some would say impossible.
A presentation given by Dr. Valendar Turner to staff of the New York Assembly Health Committee describes the problem in the context of HIV testing, using 24 slides with accompanying text explanation. It can also be obtained at the Perth Group web site. See under "Diagnosing HIV in mothers and infants as a PowerPoint presentation.
The Perth Group web site also includes many of their published scientific papers, which go into this issue and other AIDS-related matters in detail.
