What do we do?
The epidemiology department at Jefferson County Health Department monitors and assesses the health of its residents through analysis and investigation of historical case reports, emergency room data, active and passive surveillance, and other data sources. This information allows the health department to identify issues specific to Jefferson County and focus its efforts to help improve health.
Information related to the health of the county will be coming soon.
