The two main ways in which a young person can become infected with HIV are:
HIV can be passed on in both ways because the virus is present in the sexual fluids and blood of infected people. If infected blood or sexual fluid gets into
your blood, then you will become infected. If the needle or syringe used to inject drugs has already been used by someone who is infected, you will also become infected
If a man with HIV has anal intercourse without a condom, infected fluid could pass into the other man's blood stream through a tiny cut or sore inside his body
. This can be so small that you don't know about it. The risk of infection is greater with anal intercourse than with vaginal intercourse becasue the walls of
the anus are more fragile than those of the vagina.
If a man with HIV has sexual intercourse without a condom, HIV could get into the other 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. There can often be bleeding during anal intercourse especially if one partner is very agressive.
