Vaccine-Preventable Disease Surveillance Report July 2019

Hepatitis A

A graph showing hepatitis A activity has been increasing each month from June 2018 – July 2019. In July 355 cases were reported.
  • Hepatitis A activity slightly decreased from last month but has been above the previous 5-year average since April 2018.
  • 355 cases were reported in July.
  • Drug use was the most commonly reported risk factor.

Pertussis

A graph showing pertussis activity has fluctuated each month from June 2018 – July 2019. In July 49 cases were reported.
  • Pertussis activity increased from last month and was similar to the previous 5-year average.
  • 49 cases and no outbreaks were reported.
  • Incidence remained highest among infants <1 year old.

Mumps

A graph showing mumps activity has fluctuated each month from June 2018 – July 2019. In July 36 cases were reported.
  • Mumps activity increased from last month and was above the previous 5-year average.
  • 36 cases were reported, 22 of which were associated with ongoing outbreaks.
  • Incidence was highest among adults ≥19 years.

Varicella

A graph showing varicella activity has fluctuated each month from June 2018 – July 2019. In July 79 cases were reported.
  • Varicella activity decreased from last month and was above the previous 5-year average.
  • 79 cases and no outbreaks were reported.
  • Incidence was highest among infants <1 year old.

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, 2019. Counties with a proportion of 0.3%–1.2% are: Hardee, Glades, Hendry, Liberty, Dixie, Hamilton, Bradford, Gadsden, Lafayette, Washington, Gilchrist, Jackson, Taylor, Union, Levy, Calhoun, DeSoto. Counties with a proportion of 1.2%–2.5% are: Madison, Putnam, Jefferson, Baker, Holmes, Okeechobee, Franklin, Gulf, Wakulla, Suwannee, Miami-Dade, Sumter, Nassau, Leon, Polk, Highlands, Hillsborough. Counties with a proportion of 2.5%–3.6% are: Clay, Bay, Orange, Duval, Citrus, Charlotte, Manatee, Palm Beach, Pasco, Escambia, St. Lucie, Marion, Indian River, Broward, Osceola, Lake, Santa Rosa. Counties with a proportion of 3.7%–6.8% are: Hernando, Seminole, Lee, Alachua, Brevard, Collier, Pinellas, Okaloosa, Columbia, St. Johns, Martin, Monroe, Walton, Flagler, Sarasota, Volusia.

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 to 18 years with new REs is increasing each month. Statewide, the estimated prevalence of REs among children age 4 to18 years old is 3.1% with individual counties ranging from 0.3% to 6.8%. In July 2018, the statewide prevalence was 2.8%, and the prevalence has gradually increased each month since.

To learn more about REs at the local level, please visit www.flhealth.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 July 31, 2019.
