After “Sloth Fever” began spreading into Central Florida last year, experts with the University of Florida say they’ve managed a huge breakthrough in their research.

The discovery of two locally contracted cases of dengue virus and two cases of "sloth fever" believed to be contracted in Cuba has led to targeted mosquito control efforts across Central Florida.

Over the past week, nearly a dozen cases have emerged in the state. Among these, some have been reported in Central Florida.
