dengue fever

Several Florida counties have declared a public health emergency in response to a dengue outbreak officials are describing as wildly unusual. Dengue fever, a mosquito-borne illness typically concentrated in tropical regions, has prompted concern over local transmission and growing mosquito populations. Health authorities are urging residents to take precautions against bites while responding to the unexpected spread.

A global health summit is being held in Saranac Lake, New York, focused on dengue fever and how the threat it poses is changing. The gathering brings attention to the mosquito-borne disease's shifting spread, a growing concern for health experts as cases expand into new regions.
