Roughly three million Americans contract chlamydia each year [1]. Without medical intervention, a chlamydia infection can persist for years if gone unnoticed [1]. Fortunately, once diagnosed, a healthcare provider can provide patients with the right medication to treat the sexually transmitted infection (STI).

That said, how long chlamydia persists will depend on how quickly the infection is diagnosed and treated.

What are the signs and symptoms of chlamydia?

While chlamydia is common, it often has no symptoms. In fact, around 70% of females and 90% of males don’t experience any symptoms [1]. As a result, someone could have chlamydia for several years without realizing it.

That said, people who develop chlamydia symptoms typically start experiencing them one week to three months after the initial bacterial infection [2]. When symptoms do occur, they might include:

  • Abnormal genital discharge
  • Pain or discomfort during urination
  • Pelvic pain in women
  • Pain and swelling in the testicles in men
  • Pain during sexual intercourse
  • Vaginal bleeding between periods (in women) [9]

How long does untreated chlamydia last?

With or without symptoms, you may be wondering how long can chlamydia last if it goes untreated. An untreated chlamydia infection can last weeks, months, or even years without being detected and cause long-lasting health effects.

Can chlamydia go away on its own?

Chlamydia is not known to go away on its own, and delaying treatment can have serious consequences. For instance, if left untreated, it may lead to the development of:

  • Pelvic inflammatory disease (PID) – PID is a painful infection that can wreak havoc on the female reproductive system. It can cause permanent damage to the uterus, ovaries, cervix, and fallopian tubes, which may result in infertility [3].
  • Epididymis – While females may develop PID, males can develop epididymis. This condition is characterized by inflammation of the tube behind the testicles that stores and carries sperm. Like pelvic inflammatory disease, epididymis can cause pain, swelling, and infertility [4].
  • Pregnancy and birth complications – If a person with chlamydia infections becomes pregnant, they may be at greater risk for ectopic pregnancy or premature labor [5]. What’s more, their baby may become infected with chlamydia during birth. Infants who contract chlamydia can develop a lung infection or eye infection [5].

Due to these health concerns, it’s important to get screened for chlamydia regularly. People under 25 years of age should get screened at least once a year [6]. If you have multiple sex partners or have unprotected sexual intercourse, you may want to get screened even more often (in fact, in some cases chlamydia can come back even after treatment, making it even more important to get tested regularly). Early diagnosis and treatment of chlamydia can prevent potentially serious health issues and reduce your chances of spreading the chlamydial infection to others.

How long does it take to get chlamydia test results?

Regular STI or chlamydia testing can keep your body safe and healthy. Chlamydia can be detected using any of the following tests:

  • Urine test – A urine test can uncover chlamydia bacteria within your urine. These types of tests generally take two to five days to yield results. They can be administered at your healthcare provider’s office or from home.
  • Blood test – A blood test can determine if your blood contains any chlamydia bacteria antibodies. Theoretically, blood tests can return results in minutes. However, they typically need to be sent to off-site laboratories, extending that time frame to a week or more.
  • Swab test – A swab test takes a sample of tissue or fluid from the vagina, penis, anus, or throat. After that, it's sent to the laboratory to see if any chlamydia bacteria grow. Swab test results usually take two to three days.

You can usually discover if you have chlamydia within a week of taking a test, which enables you to pursue prompt chlamydia treatment once you receive your results.

How long does chlamydia last with treatment?

So, how to treat chlamydia? Once you’ve received a positive test result, your healthcare provider will likely prescribe a round of antibiotics. If you take your antibiotics properly, chlamydia has a 95% cure rate [7].

Some antibiotics for chlamydia must be taken multiple times a day for several days. Others can be administered in a single dose. Either way, it can take around one week for a chlamydia infection to go away [8]. During this treatment period, it’s important to abstain from having sex.

If you continue experiencing chlamydia symptoms after treatment, you should get re-evaluated by your healthcare provider to find out if:

  • Your initial treatment was effective.
  • You were re-infected by one of your sex partners.
  • You have another STI or health condition
