Hello doctor,

I was diagnosed with HSV 2 recently. My partner and I had unprotected sex, and she underwent a few tests, but nothing abnormal was found. But when I underwent the testing, I was positive for HSV 2; I am assuming my partner had it too. So, my question is, is there any chance that HSV 1 can be transmitted through oral sex?

Kindly give your opinion.



Welcome to

I can understand your concern.

HSV 1 (herpes simplex virus type 1) can be transmitted in a non-sexual way, and HSV 2 (herpes simplex virus type 2) is transmitted by sexual contact. If you are positive for HSV (herpes simplex virus), you need to know whether it is antibodies or antigen positive. If it is the antibodies test, it infers an old infection, so there is no need to worry, and it will be positive for ten years, and you cannot transmit the infection to your partner. But if it is an antigen test, it reveals a recent infection with more chances of infection transmission.

I hope this was helpful.

Hi doctor,

Thank you for your reply.

So is it safe for us to have oral sex both ways?

Please give your suggestions.



Welcome back to

If only the antibodies test is positive and there are no visible skin lesions, you can have oral sex both ways.

I hope this has helped.

Kindly revert for more queries.
