Communicable Disease Prevention

The Communicable Disease Program provides essential services to protect the community from disease and illness. Here are some of our services:

  • using collected data to monitor the health status of our community,
  • identifying disease trends and patterns,
  • investigating health problems and hazards in the community,
  • informing the community of health concerns and providing education to help prevent the spread of disease,
  • working closely with the healthcare community, and
  • enforcing laws and regulations to protect health.

The Peoria City/County Health Department is required by Illinois Administrative Code to investigate reportable communicable diseases. There are over 100 reportable diseases, such as salmonella, norovirus, whooping cough, and lyme disease.

Durning an outbreak of disease, the Communicable Disease team works with agencies such as the Centers for Disease Control and Prevention (CDC), Illinois Department of Public Health (IDPH), the healthcare and business community, and officials to:

  • conduct confidential investigations,
  • determine the source of illness,
  • control the spread of the disease,
  • educate the public, and
  • assure policies are in place to prevent future outbreaks.

Healthcare agencies follow this procedure to report disease.
