The Cook County Department of Public Health was established on December 10, 1945 and is the state certified public health agency for Cook County with the exception of Chicago, Evanston, Skokie, Oak Park and Stickney Township. CCDPH serves approximately 2.5 million residents in 124 municipalities and strives to meet the public health needs of our suburban Cook County jurisdiction through effective and efficient disease prevention and health promotion programs.

Our network approach to protecting and promoting health brings residents, partners and resources together to address issues facing our communities. We work to prevent the spread of about 70 reportable communicable diseases and enforce Cook County and Illinois public health laws, rules and regulations. Because of all the epidemiological information we gather and analyze, we are a major source of information about the priority health needs in each community in suburban Cook County which helps our agency, partners and the public, plan for and address emerging health threats, and promote healthy living through awareness, education, programs and community development.
