Can You Get an STI from Kissing?
Blog Content
Kissing is one of the most natural ways to express affection --- but you might wonder: can you catch an STD from kissing? While the risk is generally low, certain infections can be transmitted through close contact like kissing, especially when sores or lesions are present.
Let's talk about which STIs are possible via kissing, and how to test for infections at home with mail-in STD kits.
STIs (STDs) That Can Be Transmitted Through Kissing
Herpes (HSV-1 & HSV-2)
HSV-1 is commonly responsible for cold sores around the mouth. It is widely known to be spread via kissing or saliva.
HSV-2 usually causes genital herpes, but occasionally HSV-2 lesions can appear in the oral region, making transmission via kissing possible.
If you or your partner has active sores or blisters, avoid kissing until you are fully healed.
HPV (Human Papillomavirus)
HPV is more commonly transmitted via sexual contact, but deep oral contact or open wounds in the mouth could pose a small risk of oral HPV.
HPV is a known risk factor for oropharyngeal cancer, so awareness is key.
Syphilis
The risk is low, but possible if there is a chancre (painless sore) on the lips or inside the mouth during early infection.
If you or your partner has a sore around the mouth, avoid intimate contact until fully treated.
How to Prevent STI Transmission Through Kissing
- Avoid kissing people who have visible sores, ulcers, blisters, or cuts around the mouth.
- If you have symptoms of herpes, syphilis, or other STIs, refrain from kissing until symptoms resolve.
- HPV vaccination helps reduce your long-term risk of HPV-related disease.
- Open communication with partners about STI status, testing history, and vaccination.
- Consider regular STI screening even if you feel well.
