You can’t tell by looking at someone if they have HIV so the only way to know is by having a test. You should have a test for HIV, if you have:

• had unprotected sex with a man or a woman

• ever injected drugs, even if it was a long time ago

• had unsterile medical treatment abroad, or treatment in countries where infection control procedures are sub-standard

• had tattoos or body piercing in circumstances where infection control procedures are suboptimal

• were born or who have lived in a country that has a high prevalence of HIV
