Q: HIV infection and unprotected sex

asked by: DoctorQuestion on May 12th, 2008

I had sex with 2 different prostitutes in the same week. This is the only time I have done something this risky. I wanted to know what the statistical chances are of contracting HIV using a condom. I did wear a condom both times. As well as the chances of contracting HIV if the sex-worker did have HIV, what are the chances of contracting HIV from 2 unprotected encounters if the person was HIV positive.

Thanks for your help.

Chances for a man getting an HIV-infection from an infected woman through unprotected vaginal sex are 0.05%. If you had unprotected sex twice the risk is doubled which means 0.1%.

Chances for a man getting an HIV-infection from an infected woman through protected vaginal sex are reduced by 80% which means the total risk is 0.01%. Having unprotected sex twice makes the risk 0.02%.
