HIV/STI Data Statistics

Get Local HIV/STI Data in Chicago

The HIV/STI Surveillance Report provides a detailed picture of HIV, AIDS and STIs in Chicago, along with insights into our successes and the challenges we face in the future. Using the Healthy Chicago Public Health Agenda as a blueprint, we are enhancing our efforts to track these diseases, developing new prevention and treatment intervention strategies, reinvigorating our existing programs and services, and stepping up our policy initiatives to make structural changes to the existing service delivery systems throughout Chicago. A total of 652 new HIV diagnoses were reported among Chicago residents in 2019 – the lowest number since 1988. This represents a 14% decrease compared to 2018 (760 new diagnoses) and a 29% decrease since 2015 (913 new diagnoses). Declines in new diagnoses were recorded for all genders, all age groups, and among Black, white, Latinx, and Asian Chicagoans.
