Dengue fever is one of the most frequently occurring mosquito-borne diseases worldwide, with an estimated 390 million infections, with nearly 100 million people experiencing symptomatic disease each year. Four serotypes of dengue virus are transmitted to humans through the bite of Aedes aegypti and Ae. albopictus mosquitoes. Dengue is considered endemic in more than 100 countries in tropical or subtropical regions around the world, and risk is widespread, especially where water- holding containers (e.g., waste tires, buckets, or cans) provide abundant mosquito breeding habitat.
In 2017, 11 cases were reported in Minnesota residents. The median case age was 32 years (range, 17 to 51) and onset of symptoms occurred throughout the year from January through November. Ten cases (91%) resided in the metropolitan area, and all infections were acquired abroad. Cases reported travel to many areas of the world, including to Southeast Asia (7), Mexico and Central America (2), and Africa (2).
