Can You Get an STD from Kissing? What You Need to Know

Yes, you can get herpes or syphilis through kissing, especially if there are open sores or cuts in the mouth. While the risk is low compared to other sexual activities, testing at a clinic provides peace of mind and helps ensure your health and the health of your partner.

STDs That Can Spread Through Kissing

• Herpes (HSV-1):

  • Transmits via cold sores. 67% of adults under 50 have HSV-1 (CDC).

• Syphilis:

  • Rare, but possible if sores are present on the lips/mouth.

3 Kissing Scenarios and Risks

1. Closed-Mouth Kissing: Near-zero risk.

2. Open-Mouth Kissing: Low risk (unless sores are present).

3. Kissing with Sores: High herpes/syphilis risk.

When to Get Tested

If you or your partner have mouth sores or have kissed someone with visible symptoms, it’s a good idea to get tested.

Can HIV Spread Through Kissing?
