Dengue, 2011
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 2011, 6 cases (0.11 per 100,000
population) of dengue fever were
reported in Minnesota residents. This
was lower than the median of 10 cases
per year (range, 6 to 20) in the 90 cases
reported from 2004-2011. In 2011, the
median case age was 32 years (range,
17 to 61 years). Four cases (67%)
resided within the metropolitan area,
including 3 cases in Dakota County.
Onset of symptoms occurred from
February through November. All of the
cases represented imported infections
acquired out of state or abroad. Most
cases had traveled to Latin America (3)
or Asia (2) but 1 had potential exposure
to the virus in Florida.
