Chlamydia is a sexually transmitted infection caused by the bacterium Chlamydia trachomatis that typically affects adolescents and young adults who are sexually active. Female adolescents are physiologically more susceptible to infection than older women. Asymptomatic infection is common, though when symptoms present they could include painful urination, abnormal genital discharge, or, for women, abdominal pain due to pelvic inflammatory disease. Education on safe sexual practices can reduce transmission. Sexually active women at risk should be screened routinely to detect infection in asymptomatic patients.

Please be sure to read our health advisory regarding the change in treatment regimen for uncomplicated gonococcal infections.
