Communicable Disease (CD) Program

Staff members in the CD program verify reports of various diseases, outbreaks and conduct investigations related to reportable diseases in Illinois. Disease surveillance helps to detect potential outbreaks of illness within Lake County. The CD program serves as a resource for the general public, schools and day cares as well as community and medical entities regarding infectious diseases, infection control and prevention and pandemic preparedness. All reportable diseases in Illinois (except tuberculosis, HIV/AIDS and sexually transmitted infections) are reported to the CD program.​
