Prevention of HIV and AIDS

During vaginal or anal sex, the best way to stop HIV being passed on is to use condoms, if there is any possibility that either partner could have the virus. It can take only a single episode of unprotected intercourse (i.e. not using a condom) with an infected partner for HIV to be passed on.

However, HIV is not always passed on the first time, so it’s never too late to start practising safer sex. Other preventative measures include not sharing needles if you are injecting drugs, and avoiding a blood transfusion in any country that does not screen and treat blood.
