Expert Answers Factual Answers to Your Sexual Health Questions
Is it possible to catch HIV through a healing cold sore (oral herpes)?
The other day I had oral sex with a girl (I went down on her). I had a healing cold sore that had formed a scab and wasn’t bleeding. She wasn’t bleeding, either, but now I’m concerned that I’ve put myself at risk for HIV/AIDS. Is it possible to get HIV through a healing cold sore?
Thanks for your smart question about the risk of contracting HIV through unprotected oral sex.
The short answer is yes. It’s possible to get HIV through a healing cold sore, and someone with either oral or genital herpes has a higher risk of acquiring HIV. In fact, the Centers for Disease Control and Prevention (CDC) report that people with herpes are two to three times more likely to get HIV if exposed to the virus.
Why? Because HIV can enter the body through breaks in the skin caused by herpes...in this case, your cold sore. Also, the immune cells that respond to a herpes outbreak are the very cells that HIV targets for infection.
But...this is only true if you were sexually active with someone who is HIV positive.
Do you know if your partner is is HIV positive? If she isn't, then the situation you describe doesn’t put you at risk for HIV. And if you don’t know whether your partner has HIV or some other infection, I would encourage you (and her) to get tested for common STDs, including HIV.
