Tropical dengue fever may threaten U.S.: report

Dengue fever — a tropical infection that usually causes flu-like illness — may be poised to spread across the United States and urgent study is needed, health officials said on Tuesday.

A warming climate and less-than-stellar efforts to control mosquitoes could accelerate its spread northwards, they cautioned.

“Widespread appearance of dengue in the continental United States is a real possibility,” they wrote in a commentary in the Journal of the American Medical Association.
