  • Hepatitis A activity decreased from last month and was below the previous 5-year average.
  • 16 cases were reported in August.
  • Incidence highest among 30-39 years old.
  • 56% of cases were not up-to-date on hepatitis A vaccinations and 25% of cases had unknown vaccination status.

Meningococcal Disease

A graph showing meningococcal disease activity has fluctuated each month from September 2021 – August 2022. In August, 2 cases were reported.
  • Meningococcal disease activity decreased from last month and was above the previous 5-year average.
  • 2 cases were reported in August.

Varicella

A graph showing varicella activity has fluctuated each month from Septeber 2021 – August 2022. In August, 33 cases were reported.
  • Varicella activity decreased from last month and was below the previous 5-year average.
  • 33 cases were reported in August.
  • Incidence was highest among children 1–5 years old.
  • 73% of cases were not up-to-date on varicella vaccinations or had unknown vaccination status.

For all vaccine-preventable diseases, timely and complete vaccination is the best way to prevent infection. Although vaccinated individuals can still become infected with diseases like pertussis or varicella, in general, those who have received at least 1 dose of vaccine have less severe outcomes than those who have never been vaccinated for the disease.

A map showing the proportion of children ages 4–18 years with religious exemptions by county as of July 31, 2022.   Counties with a proportion of 0.8%–2.2% are:  Hardee Gadsden Liberty Hendry Calhoun Taylor Jackson Hamilton Bradford Dixie DeSoto Glades Franklin Putnam Madison Washington Baker    Counties with a proportion of 2.3%–3.8% are:   Okeechobee Union Wakulla Levy Gilchrist Lafayette Holmes Leon Jefferson Miami_Dade Nassau Gulf Sumter Polk Hillsborough Highlands Bay  Counties with a proportion of 3.9%–5.1% are:   Suwannee Clay Orange Lake Duval Citrus Escambia St_Lucie Indian_River Marion Alachua Palm_Beach Manatee Pasco Broward Osceola Volusia    Counties with a proportion of 5.2%–10.0% are:  Columbia Santa_Rosa Seminole Lee Charlotte Brevard Hernando Pinellas Collier Martin Monroe Okaloosa St_Johns Flagler Walton Sarasota

Unvaccinated children are at increased risk of vaccine-preventable diseases like measles, pertussis, and varicella. Communities with a higher proportion of religious exemptions (REs) to vaccination are at increased risk of vaccine-preventable disease transmission.

The proportion of children age 4–18 years with new REs are increasing each month. Statewide, the estimated prevalence of REs among children age 4–18 years old is 4.7% with individual counties ranging from 0.8– 10.4%. In August 2021, the statewide prevalence was 4.0%, and the prevalence has gradually increased each month since.

To learn more about REs at the local level, please visit FloridaHealth.gov/REmap.

All REs are required to be entered into Florida SHOTS (State Health Online Tracking System), Florida’s statewide immunization registry. The map above includes REs registered in Florida SHOTS through August 31, 2022.
