What is chlamydia?
Chlamydia is a bacterial infection that can be passed during physical, oral, or anal sex. It can occur in the reproductive organs, in the mouth, urethra, and rectum. The most common place for this bacteria in women is the cervix. Chlamydia can also be passed from the mother to the baby during a vaginal delivery when the baby passes through the birth canal. When this happens, the baby can develop lung and eye infections.
