History
The Chicago Department of Public Health was established in a 1876 reorganization of the city's health apparatus.

In 1975, the Chicago City Council revised the city's municipal code to make it clear that the nine-member Chicago Board of Health was the policy-making body for health and the Chicago Department of Health is the agency which administers the city's health programs and enforces regulations. Previously, when the Board of Health and Department of Public Health had both been under the leadership of Herman Bundesen, many of their functions merged. This 1976 change to the municipal code reverted that.

The Department participated in a series of pandemic preparedness exercises called Crimson Contagion, taking place between August 13 and 16, 2019.
