While medical research into the AIDS virus has proceeded at a phenomenal pace, with doctors making new discoveries every month--or even daily, the prospect of a vaccine or a successful treatment for the disease is still years away. Some facts about AIDS are clear, however. The number of people known to be carrying the AIDS virus has been doubling every year since it was first discovered in the United States. According to the Centers for Disease Control in Atlanta, 17,001 people have been diagnosed as actually suffering from AIDS as of February 3. However, current estimates place...
Regarding the number of AIDS cases: The estimate appeared in the New England Journal of Medicine (Nov. 1985) that about 1,750,000 people are infected with the AIDS virus. This was reported as 2,000,000 people have AIDS...
...issue of transmission of body fluids: A case was made that laboratory studies of the virus, such as which fluids contain virus or which cells can be infected, do not permit extrapolation to predict transmission under natural circumstances. The finding that tears sometimes contain virus does not mean that the virus is transmitted by tears. Knowledge regarding transmission can only be acquired using the tools of epidemiology--the observation is that several million days of contact between AIDS patients and health care providers has not resulted in infection other than by needle stick...
Haseltine said that the virus spreads primarily through sexual contact and that, as a result of promiscuity, the disease was likely to continue to spread rapidly...
Haseltine, who has been one of the leaders in AIDS research, was part of a team of scientists who announced last week an important discovering in the reproductive mechanism of the virus. The researchers are now working on a drug to slow the virus's replication...
