Women and HIV

Dec 6, 2005

This is a question out of curiosity. I know that the chances of men contracting the disease via heterosexual sex are lower than those of women. Howver, my question is: If a woman engages in sex with an HIV positive man, is there any chance that she will not get infected?

Response from Dr. Frascino


Yes, the estimated per-episode risk for a woman to acquire HIV from an HIV-positive man as a consequence of unprotected receptive penile-vaginal intercourse is 10 per 10,000 exposures. Although this estimated risk is smaller than many people would anticipate, it is nonetheless very significant. There are, of course, a large number of variables that come into play for each specific instance of HIV transmission viral strain, viral load, concurrent STDs, individual host immune response, etc. Certainly the take-home message is that heterosexual transmission accounts for the vast majority of the over 40,000,000 worldwide HIV cases. Consequently, safer sexual prevention techniques remain essential.

Stay safe. Stay well.
