Dengue fever is one of the most frequently occurring mosquito-borne diseases worldwide, with an estimated 50-100 million cases (including approximately 500,000 cases of severe dengue) each year. About 2.5% of those with severe dengue (also known as dengue hemorrhagic fever) die. Four serotypes of dengue virus are transmitted to humans through the bite of Aedes aegypti and Ae. albopictus mosquitoes. The risk is widespread in tropical or subtropical regions around the world, especially where water-holding containers (e.g., waste tires, buckets, or cans) provide abundant mosquito breeding habitat.
In 2014, 3 cases of dengue were reported in Minnesota residents, the fewest cases since 2006. In 2014, the median case age was 36 years (range, 26 to 57 years), and onset of symptoms occurred from February through July. All cases resided within the metropolitan area, but all infections were acquired abroad. Cases had travelled to Central America, the Caribbean, or South America.
