Florida health officials have confirmed the state’s first dengue-related death of 2026 as locally acquired infections reached 152, making this the state’s second-largest annual dengue count in recent decades. The Florida Department of Health confirmed the death Friday but did not release further details; the Tampa Bay Times identified the patient as an elderly Tampa woman who died Sept. 4.
The fatality puts new weight behind an outbreak that state surveillance had already shown was unusually concentrated around Tampa. In its Week 36 arbovirus report, covering Sept. 6 through Sept. 12, the department counted 152 confirmed or probable dengue infections acquired in Florida, including 41 newly reported that week. Hillsborough County accounted for 134 cases, or 88% of the statewide total. Pinellas had seven, Miami-Dade seven, Pasco two, and Orange and Palm Beach one each.
The same report said 124 Florida-acquired cases began in August, 21 in July and seven in September. Laboratory testing identified dengue virus type 2 in 135 cases and type 3 in two, with the remainder not typed. Sixteen mosquito pools in Hillsborough had tested positive for dengue virus type 2. Hillsborough, Pinellas, Miami-Dade and Duval counties remained under mosquito-borne illness alerts, while seven other counties were under advisories.
Those locally acquired infections are distinct from infections linked to travel. Florida separately recorded 186 travel-associated dengue cases during 2026, 109 of them in Miami-Dade County, according to the state report. Local transmission can begin when a mosquito bites an infected traveler and later transmits the virus to another person. County crews around Tampa have been spraying, inspecting properties for standing water and monitoring mosquitoes; recent samples had not detected the virus, an encouraging but not definitive sign that new infections may be slowing, Hillsborough County officials told The Associated Press.
For residents, the practical guidance is to treat mosquito exposure as an active health risk rather than only a nuisance. The Centers for Disease Control and Prevention says dengue is spread mainly by infected Aedes mosquitoes. Symptoms usually begin within two weeks of a bite and can include fever, pain behind the eyes, muscle or joint pain, nausea, vomiting and rash. Most people recover in about a week, but severe dengue can cause bleeding, shock and death.
There is no specific antiviral medicine for dengue. The CDC advises people with fever or compatible symptoms to contact a health-care provider, rest, drink fluids and use acetaminophen for fever or pain. Avoiding bites remains the principal prevention measure: use an EPA-registered repellent, wear clothing that covers skin where practical, maintain window and door screens, and empty containers that collect water. Because infected people can pass the virus back to mosquitoes, people who are ill should also keep preventing bites during the first week of sickness.
The state’s surveillance figures may understate total infections because many people never develop symptoms or do not seek testing. Still, the confirmed death and Hillsborough concentration establish that the current episode is not merely an increase in imported cases. It is sustained local transmission with statewide public-health implications as Florida’s mosquito season continues.
