Interpretive Summary: With the increased occurrence of dengue fever and dengue hemorrhagic in the Americas, there is a threat of dengue virus transmission occurring in the continental U.S. Critical factors needed for local transmission to occur, such as the presence of competent mosquito vectors and frequent introduction of dengue viruses, will be discussed. In addition, factors favoring dengue transmission (e.g., widespread distribution of competent vectors, a highly susceptible human population, and virus transmission in “nearby” countries) and factors that may mitigate transmission (housing conditions and lifestyles) in the southern U.S. will also be reviewed. A scenario that will support dengue transmission will be presented along with recommendations for detecting local transmission. The historical occurrence of dengue transmission in the continental U.S. (i.e., south Texas) will be presented and examined in the context of epidemic dengue activity in northern Mexico. While dengue does pose a threat to the southern U.S. and specific local conditions are present and supportive of focal transmission, the potential for major dengue outbreaks in the U.S. appears unlikely.
