  • It is spread through vaginal, anal, or oral sexual contact.

Context Most Pages Skip

Chlamydia is a common sexually transmitted infection caused by bacteria that live inside human cells. Because it often causes no symptoms, people can unknowingly carry and spread it. The bacteria can be cleared from the body with the right antibiotics, which kill the bacteria and stop the infection. Without treatment, the infection can persist and lead to complications. Testing is the only reliable way to know if you have chlamydia, and prompt treatment removes the infection and prevents further spread.
