HIV vs. FIV vs. SIV...

Dear Dr. Wohl:I know this question isn't in your "category", but, it isn't in any category active or inactive and I have come to respect and trust your feedback on this site. So, I ask you the question (and bear with me as you...

Response from David Wohl, M.D.

University of North Carolina - Chapel Hill

This definitely goes into the Miscelaneous category (no pun intented: CATegory!). I don't think it is likely to work this way. The whole monkey-human origin is based on the incredible similarity of Siamian Immunodeficiency Virus (SIV) and... Read more »

SIV

Dear Dr.Kull;A week ago, while playing with the monkeys, I got the saliva of one of the monkeys into my left eye. I read some articles on the net which state that the most of the SIV strains found in monkeys are almost identical to HIV-2 and might...

Hello Comfortable Republican,References on HIV viral evolution (as opposed to a government plot to do in gays and drug addicts, or a medical experiment gone terribly wrong, or any of a number of other urban legends/ conspiracy theories) abound in... Read more »

HIV Origin

Hi Doc. What do you think about Tulane University's recent study that suggests SIV has been up to 75,000 years ago? How does data change what we thought we knew about HIV, its lethality, and its presence amongst human populations in the past?...

Response from Robert J. Frascino, M.D.

The Robert James Frascino AIDS Foundation

Hello,I found the new information about simian immunodeficiency virus (SIV) fascinating. However, it does not alter what we know about any aspect of human immunodeficiency virus (HIV). HIV is a related but quite different virus from SIV. The... Read more »
