The Influence of Climate Change on global distributions of Dengue and Chikungunya Vector Species

by Kaylee Anderson

The global distribution of human cases of dengue and other mosquito-transmitted disease presents a serious health problem, especially considering the diseases have spread significantly in recent years. Although there is considerable research on the global distribution of these diseases, there is a second concern: range expansion by vector species. In recent years, the two main mosquito vectors, Aedes aegypti and albopictus have spread to more regions, including lower and middle latitudes, introducing ‘forest diseases’ to humans. Ae. aegypti is thought to be responsible for most massive outbreaks of dengue, so its future geographical distribution is important to predict. Continue reading
