As if the oil spill’s effects on tourism weren’t bad enough, now Key West is suffering an outbreak of dengue fever. An estimated 5 percent of Key West’s population is infected with the illness, researchers tell Reuters. The Center for Disease Control identified 27 cases in 2009 and decided to take a closer look. They sampled 240 people randomly and found that 5 percent had antibodies present in those suffering from dengue. It’s the first time since the 1940s the disease has been identified in the U.S. according to the L.A. Times.
