Hillsborough County Leads Florida in Locally-Acquired Dengue Fever Cases
Hillsborough County, Florida, is reporting the majority of locally-acquired dengue fever cases in the state.
Tampa St. Petersburg, FL, September 3, 2026 —
Hillsborough County, Florida, has become the primary location for locally-acquired dengue fever cases within the state, according to recent reports. The county is currently accounting for the majority of these infections, underscoring a significant public health concern.
Dengue fever is a mosquito-borne viral infection that can cause severe illness. It is transmitted by infected female mosquitoes, primarily of the Aedes species, such as Aedes aegypti and Aedes albopictus. These mosquitoes often bite during daylight hours and can breed in even small accumulations of water.
Symptoms of dengue fever typically appear 4 to 10 days after an infected mosquito bite and can include high fever, severe headache, pain behind the eyes, muscle and joint pain, nausea, vomiting, and rash. While many cases are mild, some can develop into severe dengue, which requires immediate medical attention and can be life-threatening.
The specific number of cases reported in Hillsborough County, as well as the timeframe for these reports, was not provided. Information regarding the source of the outbreaks, preventive measures being implemented by local health authorities, or specific public health advisories beyond the general awareness of increased local transmission was also not detailed in the available summary.
Public health officials often recommend personal protective measures to prevent mosquito bites, such as using insect repellent, wearing long sleeves and pants, and ensuring windows and doors are screened. Eliminating mosquito breeding sites by removing standing water from containers around homes and communities is also a critical component of mosquito control efforts.
As Hillsborough County reports the leading number of locally-acquired dengue cases, continued monitoring and public awareness will be key in managing the spread of the disease.
