Reportable Diseases Data

Accessibility Disclaimer

These Tableau dashboards have been designed with accessibility in mind. However, some interactive features may have keyboard or screen reader limitations, including tooltips or hover-only interactions; complex or high-density visualizations; or, certain server-rendered or platform-specific Tableau features. Text objects and individual marks may not be fully keyboard-accessible, and some functionality may differ from mouse interaction. Where full keyboard support is not available, accessible alternatives are provided, such as View Data, summary text, or CSV downloads, to ensure all users can access the underlying information.

Statewide Reported Data on Diseases

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 available for selected diseases reported since 1995. Requests for additional data or data elements, email tn.health@tn.gov or call 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.

Definitions and Data Limitations

• Only selected reportable disease and events are available on the dashboard. 
• Some records are missing County or Region of residence.
• Some diseases and events were not reportable during all years present in the data.
• Case definitions and surveillance methods often change, which can produce artificial fluctuations in the number of diseases reported. Case definitions for nationally notifiable conditions are available to view at https://wwwn.cdc.gov/nndss/conditions/search/. 
• Case counts for La Crosse neuroinvasive disease within these data were aggregated with other California serogroup viruses up through 2014.
