Gay Small's death from dengue fever on September 4 in Hillsborough County, Florida, has been confirmed by the Florida Department of Health as the state's first dengue fatality of 2026 and, per University of South Florida public-health instructor Kristi Miley, the first recorded dengue death in the Tampa Bay area in close to a hundred years. The outbreak behind her death has been building since July, but mosquito-control agencies are reporting testing results that suggest the transmission chain may be breaking.
Small turned 80 on the day she died. She had been bitten near her home on Bayshore Boulevard in Tampa, and within days her daughter Anna told Tampa's WFLA Channel 8 that her mother's hands had turned red, trembles were audible in her voice, and she had been moved to the ICU. The cause of death was septic shock and multi-organ failure. Small's family said they believe she had contracted dengue years earlier while traveling abroad, a history that matters: people with a prior dengue infection face a much higher risk of severe symptoms upon reinfection. Her late husband, Bob Small, spent his career working on dengue vaccines.
The read-through from a single death extends to the outbreak around it. Since July, Florida has been experiencing what the Tampa Bay Times calls an "unprecedented" rise in locally acquired dengue cases, with Hillsborough County at the epicenter. Both Hillsborough and Pinellas counties are now under mosquito-borne illness alerts from the Florida Department of Health. Hillsborough County Mosquito Management Services has stepped up aerial and ground insecticide and larvicide treatments while inspecting private properties for standing-water breeding sites. Pinellas County Mosquito Control Director Alissa Berro told Fox 13 that the mosquitoes which transmit dengue stay within small geographic areas, but that infected people travel across the Tampa Bay region daily, carrying the virus to new mosquito populations.
The counterargument is in the numbers. Of the last 1,500 mosquitoes submitted for testing in Hillsborough County, all returned negative for dengue, the Tampa Bay Times reported. The Florida Mosquito Control Association is pressing residents to eliminate standing water around their homes, targeting the breeding cycle at its source.
On balance, the case for containment rests on whether that testing rate holds. Two counties remain under active alerts, and, as Berro told Fox 13, dengue does not stop at county lines.
