...a dengue fever outbreak that has since led to more than two dozen confirmed cases in Key West, and, health officials fear, may be headed north.
Good news, it probably won't kill you. Bad news, you'll wish it would. Why have you never heard of this fever? Well, that's an interesting story.
Once widespread in the Western hemisphere (including the Southern U.S.), dengue fever was largely eradicated in the 1960s after the carrier mosquitoes were targeted with the pesticide DDT. The disease slowly rebounded after those efforts were discontinued, however, and while it generally stays confined to the tropics now, a handful of small, scattered outbreaks have occurred in the U.S. along the Mexican border over the past 30 years, according to the CDC.
Thank you, Rachel Carson.
