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 2016, 29 dengue cases were reported in Minnesota residents. The median case age was 38 years (range, 14 to 68 years) and onset of symptoms occurred throughout the year from January through November. Twenty-six cases (90%) resided in the metropolitan area, and all infections were acquired abroad. Cases reported travel to many areas of the world, including to Southeast Asia (11), Mexico and Central America (9), Africa (7), and the Caribbean (2).
