hello, my cousin just recently had sex knowingly with someone who is hiv positive. he is 18, 5'9 and about 150lbs. The woman who he had intercourse states she only has 1% of hiv. and they said they used a condom. Now my cousin has a girlfriend who is not in good medical condition at all. she recently had a kidney transplant, and is having open heart sugery on the 5th of june, she is 18, 5'2 and 120lbs. She doesnt know about my cousins intercourse with an hiv positive person, and that same night he had un proctected sex with his girlfriend. i was wondering if it posess a risk when she goes into sugery and if will effect her chances of living, and should i tell her cause he will not. He says that when he goes for a test in 6months and if he is positive, than he will, untill than no. Could she die from this?
