Epidemiology Program

The primary mission is to protect and promote the health of all residents and visitors in Duval County. The Epidemiology program is responsible for the surveillance and investigation of many of the reportable diseases, other than TB, STD, and HIV/AIDS. This includes enteric diseases, vaccine-preventable diseases, invasive bacterial diseases, viral hepatitis, arthropod-borne diseases, bioterrorist agents, outbreaks of disease, and many more.

Core Functions:

  • Investigate, intervene, monitor, and coordinate reporting of communicable diseases that occur in Duval County.
  • Identify the source of an agent, identify the mode and time of transmission, identify other persons who may have been exposed, and institute prompt action to prevent the spread of disease.
  • Provide education and consultation on infectious diseases to professional providers and community groups.
  • Prepare, through education and training, to respond to potential threats from the use of biological weapons.
  • Assist with studies to assess health risks associated with existing and new emerging infectious agents.
  • Review syndromic surveillance data as an active method of determining activities in the community that could be early indicators of outbreaks and incidents of bioterrorism.
  • Manage the Perinatal Hepatitis B Prevention Program to identify and protect family members and contacts of prenatal and postpartum women who are positive for hepatitis B surface antigen, a marker of viral hepatitis B infectivity.
  • Provide hepatitis testing and vaccination to individuals at risk for getting hepatitis.
  • Submit surveillance information to the State Health Office and then to the Centers for Disease Control and Prevention for inclusion in the Morbidity and Mortality Weekly Report.
  • Publish a monthly comprehensive surveillance report, which is sent via e-mail to health care providers throughout the community.
