Dengue, 2012

Dengue fever and the more clinically severe dengue hemorrhagic fever (DHF) is one of the most frequently occurring mosquito-borne diseases worldwide, with an estimated 50-100 million cases (including approximately 500,000 DHF cases and over 20,000 fatalities) each year. Four serotypes of dengue virus are transmitted to humans through the bite of certain Aedes genus mosquitoes (e.g., Aedes aegypti). 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 2012, 10 cases (0.11 per 100,000 population) of dengue fever were reported in Minnesota residents. This equaled the median of 10 cases per year (range, 6 to 20) in the 100 cases reported from 2004-2012. In 2012, the median case age was 36 years (range, 22 to 67 years). Nine cases resided within the metropolitan area. Onset of symptoms occurred from March through December. All of the cases represented imported infections acquired out of state or abroad. Cases had travelled to Latin America (6) or Asia (4).
