Dengue Cases Surge in Florida as CDC Reports National Rise

The U.S. Centers for Disease Control and Prevention reports a 359 % increase in dengue activity nationwide, with Florida leading the nation. Miami‑Dade County recorded 91 locally acquired cases in 2024 and has maintained an active mosquito‑borne illness alert through June 2026, urging residents to use personal protection and eliminate standing water.

The Florida surge mirrors a global uptrend: the World Health Organization logged over 12 million dengue infections and nearly 8 000 deaths in 2024. Rising temperatures and erratic precipitation are extending the range of Aedes aegypti mosquitoes into temperate zones, prompting climate‑informed surveillance and new control tools such as Wolbachia‑infected mosquitoes.
