Chlamydia is a sexually transmitted infection (STI) caused by the bacterium Chlamydia trachomatis. It is the most commonly reported STI in Tulsa County. Often asymptomatic, chlamydia can still cause significant reproductive health complications if left untreated, particularly for women. When symptoms do occur, they may include abnormal vaginal discharge, penile discharge, and a burning sensation during urination. Chlamydia can also be transmitted from mother to infant during childbirth, potentially leading to eye infections that may cause blindness.

This statistic is expressed as a rate per 100,000 population, based on reported cases in a single year. Zip code level data calculations were performed by the Tulsa Health Department (THD) using raw data from the Oklahoma State Department of Health (OSDH), Center for Health Statistics (CHS), Health Care Information (HCI), with population estimates from the U.S. Census Bureau (census.gov).
