Chlamydia

How Do You Get Chlamydia?

Chlamydia trachomatis, the bacteria that causes chlamydia, most often spreads through unprotected vaginal, oral, or anal sex. You get it from the semen or vaginal fluid of an infected person. It can also pass from an infected person to another through genital contact, even if there’s no sex, and by sharing sex toys with someone who’s infected.

Who Would Benefit From Getting Tested for Chlamydia?

If you have symptoms of chlamydia or have a partner who has a sexually transmitted infection (STI), you should get tested for chlamydia. 

If you’re sexually active, talk to your doctor about whether and how often you should be tested for chlamydia and other STIs. The CDC recommends regular testing if you:

• Have a vagina, are sexually active, and are younger than 25
• Have a vagina, are sexually active, are 25 or older, and have increased risk, such as a sex partner who has an STI
• Have a penis, are sexually active, and are gay or bisexual
• Are pregnant and younger than 25, or you’re 25 or older and have increased risk

You might want to consider getting tested if you’ve had unprotected sex. And it might be a good idea to get tested for STIs regularly if you’re sexually active, even if the descriptions above don’t apply to you.

Chlamydia Diagnosis

There are a few different tests your doctor can use to diagnose chlamydia. They may take a urine sample, or they may use a swab to take a sample from the urethra, vagina, cervix, or anus.Then, the sample gets sent to a lab to check for the bacteria that causes chlamydia. Your doctor also may ask you to take a home test kit.

Are chlamydia home-test kits accurate?

At-home test kits are a way to test yourself for chlamydia without going to a provider’s office. Since 2023, these tests have been available to purchase at a pharmacy or to order online. With these kits, you take a sample yourself and then send it to a lab.

Although the tests themselves should be accurate, if you don’t collect a good enough sample, your results may not be accurate. The U.S. FDA authorized the tests but has pointed out the possibility of false positives or false negatives (incorrect results) with these tests.

Chlamydia Treatments

Chlamydia is curable. Because it’s a bacterial infection, doctors can treat it with antibiotics. If you have chlamydia, your doctor will prescribe oral antibiotics, such as azithromycin (Zithromax) or doxycycline.

With treatment, your infection should clear up in about a week or two. It’s important to finish all of your antibiotics, even if you feel better.

If you have a vagina and your chlamydia infection is severe, you may need treatment in a hospital, IV antibiotics (medicine given through a vein), and pain medicine.

It’s important for your partner(s) to get treated as well, so you can avoid getting infected again and prevent spreading the infection to others.

After you finish the antibiotics, you should get retested after 3 months to be sure the infection is cured. This is particularly important if you aren’t sure your partner(s) were treated. But do get tested even if your partner(s) were treated. Don’t have sex until you’re sure both you and your partner(s) are no longer infected.

How long will I test positive for chlamydia after treatment?

You may test positive for 4 weeks after treatment for chlamydia, even though your infection will probably clear up sooner than that.

Can you get chlamydia again after treatment?

After your chlamydia is treated and cured, it’s possible to get reinfected. This is why your partner(s) should also get treatment if you get diagnosed with chlamydia.

Chlamydia Complications

If you don’t get treated for chlamydia, you run the risk of several health problems.

• If you have a vagina and your chlamydia goes untreated, it can cause pelvic inflammatory disease, which can damage your fallopian tubes (the tubes that connect your ovaries to your uterus). It can even cause infertility (the inability to have children). An untreated chlamydia infection could also increase your risk of ectopic pregnancy (when the fertilized egg implants and develops outside your uterus). Chlamydia may also cause premature births (giving birth too early). If mothers pass the infection to their children during childbirth, the newborn could have eye infections, blindness, or pneumonia.
• If you have a penis, chlamydia can cause an infection of the epididymis (the tube that carries sperm away from the testes) or proctitis -- inflammation of the rectum.
• If your chlamydia goes untreated, whether you have a vagina or a penis, you can get a condition called nongonococcal urethritis (NGU) -- an infection of the urethra.

Chlamydia Prevention

To reduce your risk of a chlamydia infection:

• If you have a penis or have sex with someone who has a penis, use condoms correctly every time you have sex.
• If you have a vagina, use dental dams during oral sex or vagina-to-vagina contact.
• Avoid sharing sex toys. If you do share them, wash them in between uses, and put a condom on toys used for penetration.
• Having multiple sex partners increases your risk of chlamydia and other STIs, so limiting your number of sex partners can help prevent infection.
• Get tested for STIs regularly, and encourage partners to get tested as well.
• If you think you’re infected, avoid sexual contact and see a doctor.

Any genital symptoms, such as discharge, burning when you pee, or an unusual sore or rash, should be a signal to stop having sex and to see a doctor right away. If you’re diagnosed with and treated for chlamydia or any other sexually transmitted disease, tell all your recent sex partners so they can see a doctor and be treated.

Because chlamydia often has no symptoms, infected people may unknowingly spread it to their sex partners.

Takeaways

Chlamydia is a common STI and often causes no symptoms, so you might not know you have it. Treatment with antibiotics can clear up the infection, but if you don’t get treated, it could lead to more serious problems. If you have any symptoms, you should get tested, and it may be a good idea to get tested regularly even if you don’t have symptoms.
