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).
