Condoms

What if I use condoms every time?

Condoms reduce the risk, but there is always a very small risk, if the condom breaks or is not used properly, of transmission.

The relative risk of HIV transmission is much higher with a transfusion of infected blood than with sexual intercourse with an infected partner.

This justifies a more stringent approach to risk reduction for transfusion.
