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 sex can pass some infections to the throat, and most of the time nobody notices. That is why people in Chicago often ask how an STD in the throat is found and what oral STD symptoms look like. These answers are grouped by theme. They explain what a clinician or a test can tell you.

The basics

Which infections can affect the throat?

Gonorrhea and chlamydia can infect the throat, according to the CDC. Syphilis, herpes, HPV and HIV can also be passed through oral sex. Each one behaves differently, so a clinician decides which tests fit your situation.

How does an infection reach the throat?

The CDC explains that STIs can spread through oral contact with the genitals, anus or a sore. The mouth and throat can be exposed whether you give or receive oral sex. Gender and orientation do not change this.

Who may want a throat test?

The CDC's 2021 STI Treatment Guidelines advise testing at each site of sexual contact for some groups, including gay, bisexual and other men who have sex with men. Anyone who has had oral sex with a new or untested partner can ask a clinician about it. The right plan depends on your exposures, and a clinician can help you sort that out.

Is this a concern in Chicago specifically?

The Illinois Department of Public Health reported a Chicago gonorrhea rate of 459.3 per 100,000 people in 2022. Its chlamydia rate was 1,023.7 per 100,000. These numbers count all body sites, not only the throat. They show that testing is a routine part of city health care.

Oral STD symptoms

What are the common oral STD symptoms?

Possible signs include a sore throat, redness, sores or ulcers in or around the mouth, and swollen glands in the neck. Many other things cause these, such as colds and strep throat. Only a clinician or a test can tell what is behind them.

Why do most throat infections cause no symptoms?

The CDC says throat infections with gonorrhea and chlamydia usually cause no symptoms. The infection can sit quietly while the person feels fine. That is the main reason testing matters more than watching for signs.

Can a sore throat be an STD?

It can be one possible cause, but most sore throats come from other things. A sore throat alone does not point to a specific infection. If you had oral sex and the soreness lingers, a clinician can swab your throat and check.

What about sores or ulcers in the mouth?

The CDC notes that syphilis can cause a sore, often painless, where the germ entered the body, including the mouth. Herpes can also cause blisters or sores. Because many conditions look similar, a clinician should look at any sore that does not heal.

Can HPV show up in the mouth or throat?

The CDC says HPV can infect the mouth and throat, and most infections clear on their own. Some types can lead to throat cancer years later. The CDC recommends HPV vaccination for children at age 11 or 12, with catch-up through age 26. Ask a clinician about vaccination if you are older.

Testing

How is an STD in the throat tested?

For gonorrhea and chlamydia, a clinician usually rubs a soft swab over the back of your throat. The sample goes to a lab for a nucleic acid amplification test. It takes a few seconds and is not a deep or painful procedure.

Does a urine test cover the throat?

No. The CDC's guidelines say to test the sites that were exposed, because a urine test checks only the urinary tract. A throat swab checks the throat, and a rectal swab checks the rectum. Tell the clinician which kinds of sex you have had so the right samples are taken.

Are syphilis, HIV and herpes found with a throat swab?

Syphilis and HIV are usually found with a blood test. Herpes is confirmed by swabbing a sore when one is present. The CDC does not recommend routine herpes blood tests for people with no symptoms. A clinician can explain which test fits your case.

Is there a routine test for HPV in the throat?

The CDC says no approved screening test exists for HPV in the mouth or throat. Dentists and doctors can check for changes during regular visits. Vaccination is the main prevention tool the CDC points to.

How long after oral sex should I wait to test?

Each infection has its own window period, meaning the time before a test can detect it. The CDC publishes these windows, and a clinician can apply them to your dates. If you are unsure, call the clinic and ask when testing makes sense for you.

Testing in Chicago

Where in Chicago can I get tested?

Chicago Department of Public Health sexual health clinics, Cook County Health, Howard Brown Health and Planned Parenthood of Illinois all offer STI testing. See the local testing list for addresses and phone numbers. For a fuller comparison, read the guide to STD testing in Chicago. The CDC also runs a locator at gettested.cdc.gov.

Do these clinics offer throat swabs?

The clinic pages we reviewed list chlamydia and gonorrhea testing but do not say which body sites they swab. Call ahead and ask for a throat swab by name. Howard Brown Health, for example, says no appointment is needed at its walk-in sexual health clinic, at 773.388.1600.

What does testing cost?

Howard Brown Health offers a sliding fee discount program based on income and family size. The CDC GetTested listing for Cook County Health's CORE Center lists a sliding scale and accepts insurance. The Chicago Department of Public Health says it provides care regardless of ability to pay, but its page does not list a price, so ask when you call.

Can a teenager get tested without a parent?

Under the Illinois Consent by Minors to Health Care Services Act, a minor age 12 or older who may have come into contact with an STD can consent to prevention, diagnosis or treatment. Parental consent is not required. Providers may try to involve family if they think it will not be harmful, and each STD case is reported to public health.

Treatment and prevention

Can a throat infection be treated?

Gonorrhea, chlamydia and syphilis are curable with treatment a clinician prescribes. The CDC recommends follow-up testing after treatment of throat gonorrhea to confirm it worked. HIV, herpes and HPV are not curable, but HIV and herpes are treatable, and many HPV infections clear on their own.

How can I lower my risk during oral sex?

The CDC says condoms and dental dams reduce the chance of passing infections during oral sex. Regular testing, and talking with partners about results, also help. Doxy-PEP is a clinician-prescribed option the CDC addressed in its 2024 guidance for some people, and Howard Brown Health offers it by appointment.

What if my partner needs treatment too?

CDC says Illinois law permits expedited partner therapy for chlamydia, gonorrhea and trichomoniasis. A clinician can provide treatment for a partner exposed within the previous 60 days, with counseling and written materials from the Illinois Department of Public Health. Syphilis is not covered, so partners should see a clinician.

Questions that are not answered here can go to the Illinois HIV/STD Hotline at 1-800-243-2437 or to the Chicago Department of Public Health. If you are looking for signs that are not specific to the throat, see STD symptoms and when to test.
