Florida Sees Surge in Locally Acquired Dengue Cases
9/5/2026, 12:15:14 AM
Core Event
In early September 2026, Florida health officials reported a sharp increase in locally acquired dengue fever. The latest arbovirus surveillance report from the Florida Department of Health (FDOH) listed 73 dengue cases statewide as of August 29, up from 41 the previous week. The majority—59 cases—were identified in Hillsborough County, with additional cases in Miami-Dade, Pinellas, Palm Beach and Pasco. Ten counties are currently under mosquito-borne illness advisories or alerts.
Background & Context
Dengue fever, a mosquito-borne flavivirus related to West Nile and yellow fever, is transmitted by *Aedes aegypti* and *Aedes albopictus*, both established in Florida. Historically, the state records a handful of locally acquired cases each year, often linked to travelers returning from endemic regions. In 2025, Florida reported 62 cases across four counties; the 2026 spike marks the highest single-year total since the disease began being tracked nationally.
Data & Statistics
- Statewide total (as of Aug. 29): 73 locally acquired cases.
- County breakdown: Hillsborough 59, Miami-Dade 7, Pinellas 5, Palm Beach 1, Pasco 1.
- Mosquito pool results: 14 positive pools in Hillsborough, four identified in the last week, all testing for DENV-2.
- CDC national count: 1,735 dengue cases in the United States and territories for 2026, up from 1,575 reported on Aug. 26. The CDC list shows 66 cases in Hillsborough and 83 in Miami-Dade, but does not publish counts for counties with fewer than three cases.
Official Statements & Responses
State Surgeon General Joseph Ladapo emailed residents ahead of the Labor Day weekend, urging the use of EPA-registered repellents, covering exposed skin, and eliminating standing water. The Centers for Disease Control and Prevention (CDC) emphasized that dengue numbers reflect patients’ residences, not necessarily infection sites, and warned that travelers returning from endemic areas should avoid mosquito bites for three weeks to prevent further spread.
Why It Matters
The surge coincides with Florida’s busiest travel period, as millions plan beach outings, boat trips, and backyard gatherings for Labor Day. Without a licensed dengue vaccine, personal protection remains the primary defense. Unchecked transmission could increase the burden on local health systems and raise the risk of severe dengue complications, which, while rare, can be fatal.
Conflicting Reports & Gaps
- Case counts: The FDOH’s county-level totals (59 in Hillsborough, 7 in Miami-Dade) differ from CDC’s published figures (66 in Hillsborough, 83 in Miami-Dade). Both agencies note that CDC data reflect patient residence and may lag behind state reports.
- Geographic coverage: CDC’s public list omits counties with fewer than three cases, leaving the exact numbers for Sarasota, Manatee and several other counties unspecified.
