Chlamydia is a common sexually transmitted infection (STI) caused by bacteria. You might not know you have chlamydia because many people don’t have signs or symptoms, such as genital pain and discharge from the vagina or penis.
Chlamydia trachomatis affects mostly young women, but it can occur in both men and women and in all age groups. It’s not difficult to treat, but if left untreated it can lead to more-serious health problems.
Signs and symptoms of Chlamydia trachomatis infection can include:
-Vaginal discharge in women
-Discharge from the penis in men
-Painful sexual intercourse in women
-Bleeding between periods and after sex in women
-Testicular pain in men
Chlamydia trachomatis can also infect the rectum, either with no signs or symptoms or with rectal pain, discharge or bleeding. You also can get chlamydial eye infections (conjunctivitis) through contact with infected body fluids.
When to see a doctor
See your doctor if you have a discharge from your vagina, penis or rectum, or if you have pain during urination. Also, see your doctor if you learn your sexual partner has chlamydia. Your doctor will likely prescribe an antibiotic even if you have no symptoms.
