HIV can be passed on because the virus is present in the sexual fluids and blood of infected people. If infected blood or sexual fluids get into your body, then you can become infected.
If a man with HIV has vaginal intercourse without a condom, infected fluid could pass into the woman’s blood stream through a tiny cut or sore inside her body. This can be so small that you don’t know about it. If a couple have anal intercourse the risk of infection is greater than with vaginal intercourse.
If a man has unprotected sex (i.e. without using a condom) with a woman infected with HIV, the AIDS virus could get into the man’s blood through a sore patch on his penis or by getting into the tube which runs down the penis.
If there is any contact with blood during sex, this increases the risk of infection. For example, there may be blood in the vagina if intercourse happens during a woman’s periods. There can also be bleeding during anal intercourse.
