A chlamydia infection typically clears up in seven to 10 days when treated with antibiotics, according to KidsHealth. An infected person doesn't always experience symptoms, which increases the risk of spreading this sexually transmitted disease to other partners. Untreated chlamydia can cause serious long-term complications, such as infertility, and pregnant mothers may transmit the disease to newborns.
