Chlamydia (kluh-MID-ee-uh) is a common sexually transmitted illness. You may not know you have chlamydia because many people never develop the signs or symptoms, which may include genital pain and a discharge from the vagina or penis.
Chlamydia affects both men and women and occurs in all age groups, though it's most prevalent among young women. Chlamydia isn't difficult to treat once you know you have it. If it's left untreated, however, chlamydia can lead to more-serious health problems.
Early-stage chlamydia infections often cause few or no signs and symptoms. When signs or symptoms do occur, they usually start one to three weeks after you've been exposed to chlamydia. Even when signs and symptoms do occur, they're often mild and passing, making them easy to overlook.

Treatments and drugs
Chlamydia is treated with antibiotics. You may be asked to take your medication in a one-time dose, or you may need to take the medication daily or multiple times a day for five to 10 days.
In most cases, the infection resolves within one to two weeks. During that time you should abstain from sex. Your sexual partner or partners also need treatment even though they may not have signs or symptoms. Otherwise, the infection can be passed back and forth between sexual partners. Having chlamydia or being treated for it in the past provides no immunity against possible reinfection in the future.
