Monitoring Disease Reports to Verify Diagnosis and Locate Areas where Outbreaks are Especially Intense

In close collaboration with our community partners (clinics, hospitals, health care providers) and the wider community, the staff of the Epidemiology and Communicable Disease Program works  to perform case investigations and contact tracing on reportable communicable disease cases. Program staff are especially interested in monitoring the frequency and pattern of health events through hospitalizations and deaths that occur as the result of outbreaks of infectious diseases such as West Nile Virus, Influenza or Hepatitis.

The surveillance and data collection function of the program is greatly assisted by the Illinois law that mandates reporting by health care providers, clinics and hospitals of any suspected or confirmed case of some 39 diseases.  The reportable diseases are divided into three categories and providers have between three hours and 7 days to make a report to the health department.
