Oral and Throat STDs: Symptoms and Testing

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.

Oral and Throat STDs: Symptoms and Testing

An STD in the throat can come from oral sex, and it often causes no symptoms at all. That is why many people in Los Angeles never learn about a throat infection unless someone tests that part of the body. These answers explain what the CDC says about oral STD symptoms, how throat testing works, and where to ask about it locally.

The basics: which infections reach the throat

Which STIs can infect the throat?

The CDC STI Treatment Guidelines (2021) describe gonorrhea, chlamydia, syphilis, herpes and HPV as infections that can involve the mouth or throat. Gonorrhea is the one most often tested for in the throat. A clinician can explain which tests fit a person's own situation.

How does an STD get into the throat?

The CDC says these infections can pass during oral sex, whether the mouth meets a penis, a vagina, or an anus. Some, like herpes and syphilis, can also pass through mouth-to-skin contact such as kissing when a sore is present. Anyone of any gender or orientation who has oral sex can be affected.

Is an STD in the throat common?

Los Angeles County does not publish a throat-only figure that we could find. The Los Angeles County Department of Public Health reported a 2024 gonorrhea rate of 252 per 100,000 people (provisional, excluding Long Beach and Pasadena), and some of those infections are in the throat. Because many throat infections are never tested, the true number is hard to know.

Can I get an infection from oral sex even without a condom failing?

Oral sex without a barrier can pass some infections, according to the CDC. Condoms and dental dams lower the chance for many infections, though herpes and HPV can also spread through skin that a barrier does not cover. Using a barrier is one tool, and regular testing is another.

Oral STD symptoms

What are the usual oral STD symptoms?

Most people with a throat infection have no symptoms, says the CDC. When symptoms do appear, they can include a sore throat, redness, swollen glands in the neck, or sores in or around the mouth. These signs overlap with colds and strep throat, so they cannot point to one cause.

Why do throat infections so often cause no symptoms?

The CDC notes that gonorrhea and chlamydia in the throat are usually silent. The throat can carry the bacteria without irritation, so there is nothing to notice. The only way to learn what is present is a test of that site.

What does a herpes sore in or near the mouth look like?

The CDC says oral herpes often shows up as small blisters or sores on or near the lips, sometimes with tingling beforehand. Not everyone who carries the virus has outbreaks. A clinician can look at a sore and run a test on it if needed.

Can syphilis show up in the mouth?

Yes. The CDC explains that the first sore of syphilis, called a chancre, can appear wherever the infection entered the body, including the lips or inside the mouth. It is often painless, so it can be missed. A blood test is the usual way syphilis is checked.

Can HPV affect the throat?

The CDC states that HPV can infect the mouth and throat, and that some types are linked to cancers at the back of the throat. Most HPV infections clear on their own and cause no symptoms. HPV is not curable, but it is manageable, and a clinician can talk through vaccination and care.

Does a sore throat mean I should test for an STI?

A sore throat has many common causes, and an STI is only one possibility. If you have had oral sex with a new or untested partner and your throat hurts for more than a few days, a clinician can sort out the options. Tell them about your sexual history so they can choose the right tests.

Throat testing

How is a throat swab test done?

A clinician or the patient rubs a soft swab across the back of the throat, which takes only a few seconds. The sample goes to a lab. The CDC treatment guidelines describe this as the standard way to test the throat for gonorrhea and chlamydia.

Does a urine test or genital swab cover the throat?

No. The CDC says testing is done at each site of possible exposure, so a urine test checks the urinary tract and does not check the throat. People who have oral sex can ask for a throat swab to be added.

Who should ask for throat testing?

The CDC recommends that men who have sex with men be tested at each site of exposure, which includes the throat, at least once a year and more often for higher-risk situations. Others who have oral sex can also ask a clinician whether throat testing makes sense. This is a conversation to have with a clinician, not a rule for everyone.

Is HIV tested with a throat swab?

HIV testing uses blood, or in some cases oral fluid, and it does not work like a throat swab for bacteria. Oral HIV tests check for antibodies in fluid from the mouth. A clinician can explain which type fits the timing of a recent exposure.

How soon after oral sex can a test find something?

Each infection has its own window period, which is the time between exposure and when a test can detect it. The CDC lists these windows by infection, and they differ. A clinician can tell you whether it is the right time to test or whether to come back.

Treatment and follow-up

Can a throat STD be treated?

Gonorrhea, chlamydia and syphilis are curable with treatment from a clinician, according to the CDC. Herpes, HPV and HIV are not curable, but they are treatable or manageable. Never take leftover medicine; a clinician chooses treatment based on the test result.

Will I need another test after treatment?

For gonorrhea in the throat, the CDC guidelines (2021) advise a follow-up test about one to two weeks after treatment, because throat infections can be harder to clear. Ask the clinician who treats you what follow-up they want. Partners often need care as well, and California allows expedited partner therapy for some infections under Health and Safety Code section 120582, as described by the CDC.

What is doxy-PEP and does it cover the throat?

Doxy-PEP is a medicine a clinician may prescribe after sex to lower the chance of certain bacterial STIs. The CDC 2024 guidance focuses on gay and bisexual men and transgender women who have had a bacterial STI in the past year. Ask a clinician whether it applies to you, since benefits differ by infection.

Getting tested in Los Angeles

Where can I get tested in Los Angeles?

The Los Angeles County Department of Public Health runs sexual health clinics, including the Central Health Center at 241 Figueroa St. and the MLK Jr. Center for Public Health at 11833 S. Wilmington Ave. Public Health says there are no patient fees at its clinics. Appointments go through (213) 449-7009, and you can find more options in our local testing list. The CDC also runs a search tool at gettested.cdc.gov.

Will the clinic swab my throat?

The clinic pages we reviewed do not say which body sites are swabbed at each location. When you book, say that you had oral sex and ask for throat testing. Our guide to STD testing in Los Angeles lists clinics, and you can read about other signs in STD symptoms in women.

Can a teen or someone without papers get tested?

California Family Code section 6926 lets people age 12 and older consent to STI testing and treatment, and Los Angeles County Public Health says its clinics test patients 12 and older without parents knowing. Public Health clinics are open to everyone regardless of citizenship, and the department says it will not report immigration status. Children's Hospital Los Angeles also lists a service for ages 12 to 24, so call (323) 361-7550 to confirm details.
