Infectious Diseases

Infectious diseases are illnesses caused by germs (such as bacteria, viruses, and fungi that enter the body, multiply, and cause infection. Some infectious diseases are contagious (or communicable), that is, spread from one person to another. Data in this report summarize annual statistics about healthcare associated infections, communicable diseases and vaccinations. The graphs and tables below compare county and Florida data.

Data Note(s)

FLHealthCHARTS.gov is provided by the Florida Department of Health, Division of Public Health Statistics and Performance Management.

  • Age-adjusted death rates are computed using the year 2000 standard population.

  • Healthcare Associated Infections (HAIs) are tracked as a benchmark of infection prevention practices and to assess the safety of certain medical devices. HAI ratios greater than 1.0 indicate more HAI events than expected, and values less than 1.0 indicate fewer HAI events. A score of zero is best.

  • When there are small numbers of cases statewide, counts are provided rather than rates and quartiles.

  • Bacterial STDs are comprised of three reportable STDs in Florida: chlamydia, gonorrhea, and syphilis.

  • Data for Children Fully Immunized: Basic Immunization Series (Aged 2 Years) are based based on a stratified, random sample survey of children born two years prior to the survey. Estimates are provided for the counties with the largest number of total births as well as statewide. Where rates would be unstable (counties with fewer births) blanks are shown. The source of the data is Florida SHOTS-Florida State Health Online Tracking System.

  • Section 1003.22, Florida Statutes, provides for the requirement of proper documentation prior to school entry into seventh grade.

  • Survey data are expressed in percentages rather than counts.

  • Green, yellow, orange and red county quartiles represent the most to the least favorable situation (1st to 4th quartile). Light to dark blue county quartiles represent density from lowest to highest (1st to 4th).
