The Centers for Disease Control and Prevention, together with Florida health officials, announced that dengue fever cases in the state have risen to 485, marking the largest outbreak on record.

The majority of infections are occurring in Hillsborough County and Miami-Dade County, and authorities are urging residents to adopt protective measures against mosquito bites.

The surge reflects a continuing increase in mosquito‑borne dengue across Florida, making this the most severe outbreak the state has experienced.
