Tampa’s Dengue Cluster Brings Florida Its First Death

Florida confirmed its first dengue death of 2026 on Sept. 18, an 80-year-old Tampa woman, as Hillsborough County logged 134 of 152 local cases. The Florida Department of Health finished its investigation that Friday and did not name the patient. Family members had already identified her as Gay Small, who died at Tampa General Hospital on Sept. 4, her birthday.

State figures for Sept. 6-12 put almost the entire outbreak on Tampa Bay, not Miami or the Keys. Hillsborough, which usually sees only a handful of local infections, now holds 88% of Florida’s locally acquired dengue.

An 80-Year-Old Tampa Walker Met One Mosquito

Anna Small, 55, said her mother walked at least five miles a day, often on Tampa’s Riverwalk, and took vitamins rather than daily pills. Gay Small lived in a condo on Bayshore Boulevard, did not drive, and had not left the city limits in more than a month, her daughter said. She had planned to spend Labor Day weekend in North Carolina with her sister and grandchildren.

The illness moved fast. Weakness and lost balance gave way to red hands and a tremble in her voice. She went from an intermediate unit on a Wednesday afternoon to intensive care around midnight Thursday, and she died Friday morning, Anna said. The death certificate lists dengue infection, septic shock, and multi-organ failure.

She was in good health and she worked hard to stay healthy and she walked and she ate right and you know, all the things that you’re supposed to do. And you know, this virus just kind of comes out of nowhere. She met the wrong mosquito, and that’s it.

Anna also said her mother had traveled widely with her late husband, Bob Small, whose work involved dengue vaccine research, and she raised the chance of an earlier, unnoticed infection. The health department confirmed a dengue death in Hillsborough County after that investigation. It did not release further personal detail.

Claire Maher, a department spokesperson, said residents and visitors should use insect repellent, stay out of high-mosquito areas, drain standing water, and wear long pants and shirts when they can, especially around sunrise and sunset.

Hillsborough County Now Holds 88% of Florida’s Local Cases

The department’s Week 36 arbovirus report, covering Sept. 6-12, lists 152 locally acquired dengue cases and 16 infected mosquito pools from six counties. Forty-one of those human cases were new that week. Onset dates cluster in August: 21 in July, 124 in August, and 7 in September.

LOCALLY ACQUIRED DENGUE IN FLORIDA, WEEK 36

Chris Wilkerson, a Hillsborough County spokesperson, called the caseload wildly unusual for the county. Pinellas, across the bay, has 7 locally acquired cases. Pasco has 2. That split is the outbreak. It is not a even statewide wave, and it is not the old South Florida pattern.

Orange County later confirmed two more locally acquired infections in the Apopka area on Sept. 18, raising that county from the weekly tally of 1 to 3 and triggering a mosquito-borne illness alert. Those extra cases sit outside the 152-case snapshot.

Travel still feeds the state. The same weekly report logs 186 travel-associated dengue cases, 109 of them in Miami-Dade County, with many trips tied to Cuba. Hillsborough logged 11 travel-associated cases. Miami remains the main door. Tampa is where local mosquitoes are now finishing the job.

A Wet Summer Fed a DENV-2 Cluster

Dengue spreads when Aedes aegypti, and sometimes Aedes albopictus, bite an infected person and then bite someone else. Both mosquitoes live in Florida. They breed in small pools, including water in tires, saucers, and bottle caps. The virus is not passed person to person.

Dr. Kartik Cherabuddi, chief epidemiology officer at Tampa General Hospital, tied this summer’s local spread to a long drought followed by almost daily rain. His staff has tested at least 10 times more people for dengue than last summer, and doctors at the hospital estimate they have treated more than 100 dengue patients. Patients often arrive with the deep ache nicknamed breakbone fever.

Hillsborough’s typed cases are almost all DENV-2: 120 of 134, with 14 still untyped and none typed as DENV-3. Statewide, 135 of 152 local cases are DENV-2. Two Miami-Dade cases are DENV-3. A single serotype running through one county is what a local chain looks like, not a scatter of unrelated imports.

DOH-Hillsborough says symptoms can start within 15 days of a bite and can look like flu: fever, severe muscle and joint pain, and sometimes a rash, usually without a cough. Many infected people never feel sick, so reported cases undercount infections. Severe disease can bring bleeding, shock, and death.

Local Dengue Moved North From the Keys

Florida went decades without local dengue after a 1934 epidemic. The continental United States, aside from scattered Texas border cases, looked similar until Key West broke that silence.

FLORIDA’S LOCAL DENGUE TURNING POINTS

1. 2009-2010: Key West records 88 locally acquired cases, the first Florida outbreak since 1934.
2. 2013: Martin County logs 24 locally acquired cases.
3. 2020: Monroe County records 72 locally acquired cases, its largest count of that period.
4. 2022-2023: Miami-Dade becomes the center of local dengue transmission in Florida, with 217 local cases in those two years; the state logged 199 locally acquired cases in 2023, 93 in 2024, and 62 in 2025.
5. July 31, 2026: DOH-Hillsborough issues an alert on a second locally acquired dengue case.
6. August 12, 2026: The county updates that alert after an eighth local case.
7. September 4-18, 2026: Gay Small dies; the weekly count reaches 134 in Hillsborough; the state confirms the death.

University of Florida extension tallies count 437 locally acquired dengue cases in Florida from 2010 through 2023, across 12 counties, with most of that burden in Miami-Dade and Monroe. Hillsborough was not that map. This year it is the map.

Michael von Fricken, an associate professor of environmental and global health at the University of Florida, has described the usual spark: a traveler gets infected abroad, comes home, and a local Aedes mosquito bites that person, then bites a neighbor. Given how common those mosquitoes are in Florida, he said the threat is not likely to fade. “I do think it’s going to be somewhat the new normal,” he said.

Crews Spray at Night While the Hospital Runs Tests

The outbreak is centered just north of Tampa. Hillsborough County Mosquito Management Services has been spraying day and night and checking properties for pooled water. Aerial work has covered neighborhoods including Seminole Heights, Ybor City, West Tampa, and Palma Ceia. Pasco County has sent crews and aircraft to help. Brian Gentry, a Pasco mosquito-control pilot, said he did not think the region had seen a season like this.

Paolo Pecora, senior environmental scientist for Hillsborough County Mosquito Management Services, said recent mosquito samples have not been finding the virus, a sign that new infections may be slowing. That sampling lag is why a death can land after the peak. Gay Small died on Sept. 4. The state confirmed the death 14 days later, on the same Friday Orange County added cases.

FDOH BITE PRECAUTIONS

• Repellent: Apply insect repellent when outdoors, especially at sunrise and sunset.
• Standing water: Drain pots, gutters, toys, and tires; Aedes mosquitoes breed in small containers.
• Clothing: Wear long pants and long sleeves when you can, and stay out of high-mosquito pockets.
• Care: Dengue is not contagious person to person; a sudden fever with bone-deep pain after a bite needs medical care, not a wait-it-out weekend.

Neighboring Pinellas remaining at 7 local cases while Hillsborough sits at 134 is the practical puzzle for the bay. Geography, yard water, and how fast each mosquito unit hit the cluster all play in. Dumping standing water is still the household move that does not wait on a helicopter.

Puerto Rico Still Reports More U.S. Cases Than Florida

The Centers for Disease Control and Prevention’s current U.S. dengue case counts, updated Sept. 16, show 1,927 reported dengue cases in U.S. states and territories across 40 jurisdictions. Puerto Rico accounts for 907. American Samoa accounts for 437. Florida’s own books for Week 36 show 152 local cases plus 186 travel-associated cases, or 338 in all, still well below Puerto Rico’s tally.

Those CDC figures mix travel and local infections and are reported by county of residence, so they are not the same ledger as Florida’s local-exposure table. They do show where dengue already lives in U.S. jurisdiction: Puerto Rico first, then the Pacific territory, then Florida.

Worldwide, the picture is large and, this year, smaller than the last two peaks. WHO surveillance for January through June 2026 counted 1.6 million cases and more than 700 deaths from 89 countries, with 81% of cases in the Americas. In 2024, WHO recorded 14.2 million cases and more than 10,000 deaths, the highest year on its books. The Pan American Health Organization’s week-34 update counted 1,626,962 suspected dengue cases in the Americas, a 57% drop from the same point in 2025.

Florida’s death is one case in that global file. It is also the first time this year the state’s local chain has been billed in a Tampa hospital, in a county that opened July with two local cases and closed mid-September with 134 and a confirmed death.

Pecora’s traps are coming up cleaner. The county that used to see a handful of local dengue infections still holds 88% of Florida’s 152. That is the map crews will be working when the next traveler and the next wet week line up again.
