Three Florida counties—Pasco, Hillsborough and Pinellas—declared local states of emergency as dengue cases spread. The declarations let officials speed up mosquito-control work, make emergency purchases, coordinate responses and seek assistance or reimbursement where applicable.

Florida reported 190 locally acquired cases across six counties in surveillance data covering cases with onset through 19 September: 170 in Hillsborough, seven each in Miami-Dade and Pinellas, three in Orange, two in Pasco and one in Palm Beach. These are separate from travel-associated cases. Dengue can cause fever, aches, nausea and rash, and can rarely become life-threatening; officials advise removing standing water and taking steps to avoid mosquito bites.
