This page is general health information, not medical advice. It cannot tell you whether you have an infection. A clinician can, and the testing options on this site are a good place to start.

Can you get an STD from kissing? Sometimes, yes, but only a few infections spread this way. Most of the ones people worry about do not.

This guide walks you through how to sort out kissing risk for yourself. You will learn which infections matter, which situations raise the chance, and what to do next if you are concerned. It is written for people in Orlando, with local testing options at the end.

What you need before you start

This is a thinking exercise, so the materials are simple:

A few quiet minutes and honest answers to a few questions about your own situation.
Any symptoms you have noticed, such as a sore, blister or tingling on or near the mouth.
The date of your last test, if you have had one.
A phone to call a clinic, if you decide to ask a clinician.

Step 1: Know which infections can spread through kissing

Kissing is skin and saliva contact. Only infections that live on the lips, mouth or throat, or in saliva, can pass this way.

Herpes (HSV-1 and HSV-2)

Herpes is the most common answer to this question. The CDC explains that oral herpes, usually caused by HSV-1, spreads through contact with saliva or with skin on or near the mouth. Many people get it in childhood from non-sexual contact.

The CDC also notes that HSV-1 can pass to the genitals during oral sex. Herpes can spread even when no sore is visible, though the risk is generally higher when there is an active sore.

Herpes is not curable, but it is manageable. A clinician can prescribe medicine that reduces outbreaks.

Syphilis

The CDC says syphilis spreads through direct contact with a syphilis sore. Sores can show up on the lips or inside the mouth, and they are often painless. So kissing someone who has a sore in or around the mouth can be a route.

Syphilis is curable with treatment from a clinician. In Orange County, FLHealthCHARTS (Florida Department of Health) reports 9.3 primary and secondary syphilis cases per 100,000 people in 2025, or 143 cases. The statewide figure was 12.4 per 100,000.

Infections that are not sexually transmitted but can pass by kissing

Colds, mono and cold sores spread through saliva. Mono and cytomegalovirus are common and are not treated as STIs. If you are worried about a sore throat after kissing, a clinician can sort out the cause.

Step 2: Know which infections are unlikely to spread by kissing

This is where much of the worry comes from, so it helps to be specific.

HIV. The CDC says HIV is not spread by saliva and not spread through closed-mouth kissing. The CDC describes the risk from open-mouth kissing as very low. It is only a concern in the rare case that both people have blood or sores in the mouth. HIV spreads mainly through certain body fluids during sex or shared needles.
Chlamydia and gonorrhea. The CDC describes these as spreading through sex, including oral sex. Both can infect the throat. Kissing is not described by the CDC as a main route.
HPV. The CDC links oral HPV mainly to oral sex and other sexual contact. Evidence that ordinary kissing spreads it is limited.
Trichomoniasis. This is a genital infection. Kissing is not a route.

This does not mean any single contact is risk-free. It means the pattern is narrow, and knowing it can lower worry.

Step 3: Check the situations that raise the chance

Go through these questions. Each "yes" is a reason to think about talking to a clinician.

Did the other person have a sore, blister or crusted spot on or near the mouth?
Did you have a cut, ulcer or bleeding gums at the time?
Has a partner told you they have herpes or syphilis, or been told they were exposed?
Has anything else happened that raises risk, such as oral sex or sex without a barrier?

If your answers are mostly "no" and the contact was closed-mouth or ordinary open-mouth kissing, the infections discussed above are less likely routes. Only a clinician or a test can tell you more about your own situation.

Step 4: Look at your body, without panic

Symptoms are clues, not answers. Things worth showing a clinician include:

A tingling, burning or itching spot on the lip or mouth, sometimes before a blister appears.
A painless sore or ulcer in or around the mouth.
A rash, especially on the palms or soles, or swollen glands.
A sore throat that does not go away.

Many causes can look alike, and a lot of them are harmless. Many STIs also cause no symptoms at all, so a quiet mouth does not settle the question either way. A clinician can examine a sore and run the right test.

Step 5: Decide whether to get tested, and where

Consider an appointment if you answered "yes" to anything in Step 3, if you have a sore or symptom from Step 4, or if you simply want certainty. Wanting to know is reason enough.

Orlando has several options, and our local testing list shows them side by side. Here is one example.

The Florida Department of Health in Orange County runs an STD clinic at 832 West Central Blvd, Orlando, FL 32805. Its county page describes it as walk-in and first come, first served, and asks for a picture ID. The page lists testing for chlamydia, gonorrhea, syphilis and HIV. It says clinic fees range from $20 and up, with a sliding scale after an eligibility screening. It lists payment by cash, card, Medicaid or Medicare.

The county page gives hours of Monday to Friday, 7:30 a.m. to 4 p.m., with a lunch closure from 12 to 1 p.m. Other county pages show different hours, so call 407-858-1400 before you go. The county page says results take about one week.

If you are under 18, Florida law (Fla. Stat. s. 384.30, per the Florida Legislature's Online Sunshine site) says parental consent is not required for examination or treatment of a sexually transmissible disease. It also says the fact of a minor's visit is confidential.

Step 6: Plan your prevention going forward

You do not need to stop kissing. A few habits reduce the small risk that exists:

Skip kissing while you or a partner has an active sore or blister around the mouth.
Talk openly with partners about herpes and syphilis status and recent testing. Honest conversations work better with curiosity than blame.
Avoid oral contact with a sore on any part of the body until a clinician has looked at it.
Ask a clinician about regular testing if your partners or situation change.

HIV prevention depends on the kind of contact, and kissing is not a main route. If you want to understand medicine that lowers the chance of getting HIV through sex, read about PrEP in Orlando.

Tips and common mistakes to avoid

Assuming no sore means no herpes. The CDC says herpes can spread without visible sores. A normal-looking mouth does not guarantee anything.
Treating every cold sore as a sign of something serious. Oral herpes is very common, and many adults carry HSV-1. It is manageable and carries no moral weight.
Worrying about HIV from a kiss. The CDC puts closed-mouth kissing outside the routes. If you are anxious, a clinician can talk it through with you.
Ignoring a painless sore. Syphilis sores often do not hurt, so a sore that does not hurt still deserves a look.
Waiting for symptoms before testing. Many STIs show no signs. A test, not a guess, gives information.
Self-treating. Treatment is something a clinician prescribes after an exam or test.

What to expect afterward

Most kissing contact, especially without sores, is unlikely to lead to a sexually transmitted infection. Many people who go through these steps find that their risk was low and that a conversation or a routine test gave them peace of mind.

If a clinician does find herpes, it can usually be managed with prescribed medicine, and many people have few outbreaks over time. Syphilis, if found, can be cured with treatment from a clinician, and earlier care generally means fewer problems. Results vary by person, and your clinician is the best source for what to expect in your case.

In short, can you get an STD from kissing? Yes, in a limited set of situations, mostly involving herpes or a syphilis sore. For most other infections, kissing is not the usual route. Knowing the difference helps you act on facts instead of fear.
