Communicable Diseases

Communicable diseases are infectious diseases that are spread from person to person (e.g., E. coli, Salmonella, chickenpox) or from animals to people (e.g., rabies, H1N1). There are about 70 communicable diseases that are reportable to the Cook County Department of Public Health (CCDPH) so we can prevent the spread. The CCDPH Reportable Diseases poster is available for download in two sizes: letter-size (8.5X11, PDF) and pocket-size (5X7, PDF)

In addition, we prevent the spread of infectious diseases through disease surveillance, community education, outbreak response and by providing recommendations to control the spread of communicable diseases in suburban Cook County.
