Welcome to the forum. Thanks for your question.

From the beginning of the recognized worldwide HIV/AIDS epidemic (in the 1980s), a bite by an infected person was assumed to carry risk of transmission of HIV. This especially drove police to protect themselves against (and worry about) biting when in an altercation. However, I am unaware of any cases at all of reported, proved instances of actual transmission by biting. If it happens, it is very rare. Why not? I would guess it is because salvia kills HIV, and therefore HIV infected people typically don't have much virus in the mouth (this is also why oral sex is very low risk). And probably there isn't a lot of opportunity for the biter's blood to enter the bite wound.

If you are ever bitten by another person, and that person has HIV or is in a high risk group (gay man, injection drug user, immigrant from a country with lots of HIV/AIDS), you should see a health professional for personal advice about prevention, testing, etc. But the odds would be strongly against HIV transmission in that circumstance.

I hope this has been helpful. Let me know if anything isn't clear.

My friend bite but it was friendly..there was no wound..even if there was a wound I think I should be worried because hiv transmission from biting is a rare case or perhaps it has not occured at all.  Am I right??

If the skin wasn't broken, for sure the risk of HIV is zero, even if the biter has HIV (which probably s/he does not). Even if there was a wound, the next step would be to speak with that person about his or her HIV status and, if any possibility of risk, to be tested for it. But since there was no skin break, this is a zero risk situation and I see no reason to take this any further.

a) Already answered:  read my original reply. As far as I know, there are no known cases of transmission by biting or being bitten.

b) These could be risks for HIV, but very low risk -- much lower than sexual intercourse.
