How common is hiv in the u.s.? i had a sexual encounter with a male and didn't realize the condom was broke until after sex.

Twelve STDs: There are twelve common stds, five of which are potentially life threatening. Hiv is very much a reality in america. The risk of hiv, however, is diminishing slowly as more and more infected people get on good medications and their viral activity is suppressed. I would advise you go to your doctor for testing when you feel it appropriate.
