The four new cases were reported from Miami-Dade (2), Hardee and Polk counties.

In 2023, 15 cases of locally acquired dengue have been reported in Broward (2), Hardee, Miami-Dade (11) and Polk counties with onsets in January, March, June (3), and July (10).

Of the fifteen cases, 11 were serotyped as DENV-3, three were DENV-2 and one case was DENV-1.

In addition to the locally acquired cases, Florida has reported 234 cases with a travel history to a dengue-endemic area in the two weeks prior to onset. 70 percent of the travel associated cases were linked to Cuba.

Bay, Hardee, Jefferson, Nassau, Orange, Polk, St. Johns, and Walton counties are currently under a mosquito-borne illness advisory. Broward, Escambia, Manatee, Miami-Dade, and Sarasota counties are currently under a mosquito-borne illness alert.
