How come does AIDS or HIV infect by Sexual intercourse? in which way?

Question

I mean, if no bleeding occured during sexual intercourse, still we get Aids? How come? Because as far as I know, it doesnt pass through salva or kissing.. so If there is no bleeding, we still certainly get aids from a persons vagina liquids.. Is there a chance of NOT to get infected by HIV, after an unprotected intercourse??? For example as someone's blood or sexual liquids contacts your skin(including penis skin), do we definitely get infected by HIV, or only when our skin is broken during contact? Thanks..

Answer 1

Even if there is no bleeding, HIV can be transmitted during sexual intercourse. The virus is present not only in blood, but in semen and vaginal fluids. It is also transmitted through breaks in the mucous membranes, even if there is no obvious bleeding.

The odds of NOT contracting HIV in a single act of unprotected sexual intercourse are higher than the odds of contracting it; depending on where inthe world you are, the viral load of the infected person, immunecompetency, and other things like whether there was any breaks/trauma in skin/mucous membranes.

In short, YES you can contract HIV in a single unprotected act of sex, but whether you do depends on many factors, as mentioned above. Odds range from 1 chance in 500 to 1 in 3000 depedning.

Hope this helps.
