Hillsborough County has extended its dengue-related state of local emergency through Thursday, Nov. 12, as state surveillance lists 407 locally acquired cases in the county this year.

County Administrator Bonnie Wise signed the extension Nov. 5, according to the county's announcement. The order supports the mosquito-control response and provides a path for reimbursement of some expenses.

The Florida Department of Health's surveillance report for Oct. 25-31 lists 524 locally acquired dengue cases statewide in 2026, including 407 in Hillsborough, 80 in Pinellas and four in Pasco. Hillsborough accounts for about 78% of that statewide total.

Those figures describe cases acquired in Florida. The report separately tracks infections associated with international travel. The county totals do not identify Lutz, Odessa or Land O' Lakes as neighborhood hotspots.

The report added 39 locally acquired cases statewide during the reporting week. Hillsborough's weekly increase was 22, its lowest in several weeks, WUSF reported Nov. 6. The cumulative total remains 407 despite that slower weekly increase.

Mosquito control continues

Hillsborough said crews are increasing treatments by air and ground because surveillance continues to detect dengue virus in mosquitoes in multiple neighborhoods. The county is coordinating education and treatment with the local health department.

Residents can use the county's emergency update to reach treatment information and sign up for notifications about localized aerial treatments.

Protecting against bites

The Florida Department of Health in Hillsborough County advises residents to use insect repellent, cover arms and legs with loose clothing and drain standing water. The department urges people with symptoms after mosquito exposure to seek medical attention.
