Tennessee Public Health Dashboards

Diseases and Events Reported to TDH

Overview of Available Data

• The interactive disease data dashboard above displays data on diseases and events reported to the Tennessee Department of Health (TDH), Division of Communicable and Environmental Diseases and Emergency Preparedness (CEDEP). The dashboard may be used to view data at the state or county/regional level over multiple years.
• Data are made available for selected diseases reported since 1995. Additional data or data elements may be requested by emailing tn.health@tn.gov or calling CEDEP at 1-800-404-3006.
• Rates of disease (the number of diseases reported per 100,000 population) were calculated using population projections provided the TDH Division of Population Health. 
• Eighty-nine county health departments operated by the TDH are grouped into 7 administrative regions. Six metropolitan areas and the county they are located within provide service under contract from the TDH. For a map of metropolitan counties and regional health jurisdictions.
