Communicable Disease and Epidemiology Program

During normal day-to-day operations, there are two components of the Communicable Disease and Epidemiology (CDE) Program. CDE operates under the direct supervision of the Communicable Disease and Epidemiology Manager and general direction of the Medical Officer.

The two CDE components are:

  1. Surveillance (SUR). The systematic collection, analysis, interpretation, dissemination, and consolidation of data pertaining to the occurrence of a specific disease. Examples include case investigations, school absenteeism data, syndromic surveillance system data, Influenza-Like-Illness (ILI) data from hospitals and physicians.
  2. Epidemiology (EPI). The study of the distribution and determinants (factors or events that are capable of bringing about a change in the health status of a population) of health and disease in populations, morbidity (occurrence of illness or illnesses in a population), injuries, disability, and mortality (the occurrence of death in a population).

DuPage County health care providers and hospitals are required by law (77 Illinois Administrative Code 690) to report any suspected or confirmed cases of selected communicable diseases to the DuPage County Health Department within a specified numbers of hours or days. Diseases are to be reported either immediately (within 3 hours), within 24 hours, or within 7 days.
