Hello and thank you for your inquiry.

We understand that you are wondering if you are at risk of acquiring HIV when your hand touched a dirty band aid. This situation does not carry a risk of HIV transmission. (No Risk)

In order for an HIV transmission to occur, there must be HIV present in a body fluid, that fluid must have direct contact with your blood stream, and you must be engaging in a high risk activity. (1)

In the scenario you have provided, any blood on the band-aid would have been dried. Even in the unlikely event that the blood had contained the HIV virus, HIV is very fragile.
Air does not "kill" HIV, but exposure to air dries the fluid that contained the virus, and that will destroy or break up much of the virus very quickly. (2)

Presumably the large cut on your hand was not open and bleeding, but scabbed over, and therefore did not provide adequate access to your bloodstream for an HIV transmission to occur, especially from a small amount of dried blood on a band-aid.

Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health related questions

Regards,
AIDS Vancouver Helpline Volunteer, Dyson
