Chicago Department of Public Health

What Chicago Department of Public Health does

The Chicago Department of Public Health (CDPH) is the municipal public health authority for the City of Chicago, operating as a department within city government since 1835 and currently employing 501-1,000 staff. Headquartered at City Hall (121 N. LaSalle Street), CDPH delivers public health services including disease surveillance and outbreak response, behavioral health, overdose prevention, maternal and infant care, and environmental health monitoring. Its service population is the residents of Chicago, with prioritized programs for high-risk populations including high-risk youth, violence survivors, individuals with serious mental illness, people experiencing homelessness, individuals at high risk of overdose, and Black women and families on the South Side facing maternal health disparities.

CDPH's core operational assets include seven city-run Mental Health Clinics, the Healthy Chicago Mental Health Collective (a $16.2 million mobilization of 53 partner organizations serving 53 high-need community areas and enrolling 173,000+ new clients over five years), and Open Air Chicago — the nation's largest urban air quality sensor network with 277 solar-powered sensors deployed in partnership with the University of Illinois Chicago. The department also supports the Chicago South Side Birth Center, a $7.4 million nonprofit facility under development at 8301 S. South Shore Drive. Recent operational milestones include the third consecutive year of declining opioid overdose deaths in Cook County and collaborative investigation with the Illinois Department of Public Health and CDC of a measles exposure at O'Hare International Airport in June 2026.

CDPH is funded entirely through public appropriations — City of Chicago budget allocations, state funds (including Illinois DHS grants, Opioid Settlement Funds, and Ryan White Part A), and federal grants (including CDC Epidemiology and Laboratory Capacity funding). Approximately $81.4 million in unspent federal COVID funds was voluntarily returned to the federal government in May 2026. The department is currently in a leadership transition following the May 2026 resignation of Commissioner Dr. Olusimbo Ige and has undergone significant organizational upheaval including the termination of over two dozen employees and elimination of programs such as Healthy Chicago Equity Zones.
