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

Kissing is low-risk for STDs – but not zero-risk. We explain CDC-backed exceptions (like herpes) and why clinic testing provides peace of mind.

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?

No. HIV requires blood/semen contact (CDC).
