HIV Transmission Through Mouth Ulcer


Hi there,

I went to see a sex worker about two weeks ago. I did receive a protected blowjob and handjob from her. I also fingered her and there was a small break in the skin. I read that both of the act will be considered little to no risk or of negligible risk. That for the HIV to be transmitted by the cut on my finger, the cut has to be relatively large and is have quite a bleeding.

What worry me is that when I went to see her, I have a recently healed ulcer in my mouth, at the base of the gum. Can HIV be transmitted via that ulcer? It's not that large either. Can you please explain to me how can HIV be transmitted via that ulcer and how does the ulcer should be (in term of size, bleeding or not, etc) for HIV to be transmitted?



Thank you for your inquiry. From what we gather from the question, you were asking about HIV transmission through a mouth ulcer. For a risk to exist, specific HIV (blood, semen, pre-cum, vaginal fluid, rectal fluid) positive fluids must come into direct contact with the blood stream of an HIV negative person. This can be through open wounds in the mouth. HIV is not spread through saliva. From the information given, the ulcer was healed and there was no bleeding involved. This scenario is determined to be negligible risk.

We recommend using a barrier like a condom or dental dam during oral sex to reduce the risk of transmitting HIV or other sexually transmitted infections.
