Have you been exposed to HIV within the last 72 hours?

Have you had sex with someone who has HIV or is at high risk of HIV.  For example, you may have had sex without a condom with:

Someone from a country where HIV is more common;

Anal sex with a man who has sex with other men;

Sex with someone who is HIV+ who does not take their HIV treatment.   

We know that someone with HIV who is taking their treatment well, is unlikely to pass on their virus to sexual partners.
