A type of bacteria, Chlamydia trachomatis, causes chlamydia.
How Is Chlamydia Diagnosed?
To find out if someone has chlamydia, health care providers do tests on:
fluid or discharge from the vagina, urethra, eye, or anus
How Is Chlamydia Treated?
Health care providers treat chlamydia with antibiotics. It is important to get tested again 3 months after treatment to make sure the infection is cured, even if a person has no symptoms.
For the infection to go away, someone needs to:
Take the antibiotics exactly as prescribed. They should not stop taking the medicine early because the infection could come back.
Tell all partners from the last 2 months to get tested and treated (even if they don’t have symptoms).
Not have sex until they and their partners are treated and any symptoms of chlamydia are gone (such as pain in the lower belly; fever; unusual discharge from the vagina, penis, or anus; and pain when peeing).
People can get chlamydia again if:
Their partners aren't treated with antibiotics.
They get treated but then have sex with someone else who has chlamydia.
