What is it?

Chlamydia is an STI produced by a bacteria called Chlamydia trachomatis. Is the most reported bacterial STI in the United States and is common among people ages 15-24.

If it goes untreated, chlamydia can lead to serious health problems. Untreated chlamydia can cause pelvic inflammatory disease (PID) in people with uteruses. Chlamydia can cause inflammation in the tubes that carry sperm from the testicles, among other consequences.

How can someone get it?

People can get chlamydia through vaginal, anal, or oral sex with someone who has chlamydia. People can be infected with chlamydia in their vagina, anus, penis, and throat. It can spread from one part of the body to another. A pregnant person can pass it to their baby during childbirth.

How can it be prevented?
Chlamydia can be prevented by

  • using condoms, internal condoms, or dental dams as a barrier between the bodies;
  • not having sex or being abstinent;
  • getting tested regularly, especially with new sexual partners, to know your status;
  • talking openly, honestly, and without judgment with sexual partners about STIs;
  • learning how to care of your health.


The majority of people who have chlamydia have no symptoms.

Discharge (fluid) from the vagina or penis that is different than usual
