Chlamydia is an infectious cause of human eye and genital disease.
Chlamydia Trachomatis is naturally found living only inside human cells and is one of the most common sexually transmitted infections in people worldwide — about 2.8 million cases of Chlamydia infections occur in the United States each year. Chlamydia can be transmitted during vaginal, anal, or oral sex, and can be passed from an infected mother to her baby during vaginal childbirth. Many people with Chlamydia exhibit no symptoms of infection. Between half and three-quarters of all women who have Chlamydia have no symptoms and do not know that they are infected. If untreated, Chlamydia infections can cause serious reproductive and other health problems with both short-term and long-term consequences.

Detection:
Nucleic acid amplification tests (NAAT), such as polymerase chain reaction (PCR), transcription mediated amplification (TMA), and the DNA strand displacement assay (SDA) now are the mainstays.

Treatment:
Chlamydia trachomatis infection can be effectively cured with antibiotics once it is detected.

Consequences:
Chlamydial infections can cause serious reproductive and other health problems with both short-term and long-term consequences.
