Dengue Fever

Factsheet

Dengue fever is a mosquito-borne disease characterized by acute onset of fever and rash. Dengue fever is caused by one of four viral serotypes (dengue 14). Infection from one viral type does not provide immunity to the others, and may lead to more severe disease such as dengue hemorrhagic fever and dengue shock syndrome.

Dengue virus is not found in Oregon. Reported cases come from travelers returning from the tropics and subtropics where dengue fever is endemic (occurs regularly). Travelers are infected when they are bitten by a dengue-infected Aedes mosquito.

 

Prevention
There is no specific treatment or vaccine for dengue fever; however, there are effective methods to prevent infection. Aedes mosquitoes bite during both day and night. Use both physical (i.e., long sleeves, bed nets) and chemical (i.e., EPA-approved 20–30% DEET products) mosquito protective barriers. Contact your health care provider if you think you may have gotten dengue during your travels.
