Technical Abstract: Dengue is the most important mosquito-borne viral disease of humans and commonly occurs in many tropical countries around the world. The principal vector is Aedes aegypti which is produced in a variety of water holding containers occurring in the domestic environment. In the last 30 years, there has been a remarkable increase in dengue incidence in the Americas which poses a threat to dengue transmission in the continental US. While several factors and conditions favor the occurrence of dengue transmission in the US, conversely, other factors mitigate this occurrence. Since 1945, local dengue transmission in the continental US has only sporadically been detected in south Texas where a total of 63 locally acquired infections were detected through 2005. This presentation reviews some of the factors that influence the presence of this disease and analyzes the likelihood of indigenous dengue occurring in the southeastern US.
