• Chlamydia is one of the most common sexually transmitted infections.
  • It is caused by bacteria called Chlamydia trachomatis.
  • Chlamydia can be passed from one person to another during condomless sex (vaginal, oral or anal).
  • If you are pregnant and have chlamydia, you can give it to your baby during childbirth.
  • If you have an STD, you have a greater risk of getting HIV or transmitting it to someone else.
  • Using a condom every time you have sex can protect you from chlamydia.
  • Most people don’t have symptoms. That’s why testing is important.
  • Symptoms can include pain or burning with peeing, pain with sex, anal pain, or abnormal discharge from the penis, vagina, or anus.
  • Chlamydia can cause unusual vaginal bleeding.
  • Chlamydia can cause pain and swelling in the testicles, and infection of the uterus can cause belly pain.
  • Untreated chlamydia can cause infertility.
  • Chlamydia tests are done on swabs from a site where you have sex (penis, vagina, mouth, or anus) or on urine.
  • Sexually active people living with HIV or people with more than one sex partner should be tested at least once a year.
  • Sexually active people with female gender at birth who are less than 25 years old should be screened once a year.
  • Sexually active men or transwomen who have male partners should be tested at least once a year and should consider testing up to every 3 months.
  • Persons who have symptoms, are exposed to a partner with chlamydia, or who are pregnant should be examined and tested by a health care provider.
  • Chlamydia is treated with antibiotics (medicine) you take by mouth.
  • Your sex partners in the last 60 days also need to be tested and treated.
  • Follow the instructions from your health care provider about when you can have sex again.
  • Everyone with a positive chlamydia test should get tested for syphilis and HIV.
  • Repeat chlamydia testing 3 months after being treated for a positive test.
