DRIED BLOOD ON CUP

QUESTION
I recently drank out of a cup and only afterwards noticed that there was dried blood on the rim. I had a cut on my lip, but the blood on the cup was old. Could I have contracted anything?

ANSWER
You do not have much to worry about regarding STDs or HIV. STDs are only passed sexually and HIV doesn't last long once it's exposed to air or light. HIV cannot be transmitted by sharing plates, glasses, silverware, kissing or touching. You can find additional information about HIV transmission on our website, SFCityClinic.org or at SFHIV.org.

To your health,
Dr. K
