mosquito control experts

Health experts say the United States is experiencing its worst dengue fever outbreak since the 1930s. The mosquito-borne illness, typically rare in much of the country, has drawn attention as cases rise, prompting questions about the scale of the outbreak, which regions are most affected, and what authorities are doing to control the spread.

Health authorities in Lombardy are warning that dengue is no longer just an imported tropical disease but is now being transmitted locally, calling it a new threat to public health. Experts link the change to rising temperatures making the region more hospitable to tiger mosquitoes, which can carry the virus, and urge stronger mosquito control measures.

Health authorities in Florida are reporting a dengue outbreak, with experts warning it may signal a longer-term viral threat to the region. Local transmission of the mosquito-borne virus has raised concern that rising temperatures could allow dengue to take hold in parts of the United States previously considered low risk. Commentators are urging stronger mosquito control and surveillance as cases continue to be monitored.
