Resumo: Dengue is a potentially life-threatening tropical disease caused by four serotypes of virus, dengue virus 1, -2, -3, and -4. Worldwide, as many as 390 million people become infected with dengue virus each year after being bitten by infectious Aedes mosquitoes. Unfortunately, there is no commercially available vaccine to prevent dengue; so, dengue prevention is attempted by controlling Aedes mosquitoes. Since the Aedes aegypti mosquito is responsible for most dengue virus infections worldwide, most dengue control efforts target this mosquito. However, Aedes mediovittatus, a common mosquito in the Caribbean, may also transmit dengue virus in Puerto Rico. Our goal was to compare dengue virus transmission by Aedes mediovittatus and Aedes aegypti mosquitoes for four serotypes of dengue virus. In the laboratory, we exposed Aedes mediovittatus and Aedes aegypti mosquitoes with dengue virus-1-4. We found that similar numbers of Aedes mediovittatus and Aedes aegypti mosquitoes became infected with dengue virus-1-3, but differed in dengue virus 4 infection rates.
