Past and future spread of the arbovirus vectors Aedes aegypti and Aedes albopictus

  • States that the global population at risk from mosquito-borne diseases—including dengue, yellow fever, chikungunya and Zika—is expanding in concert with changes in the distribution of two key vectors: Aedes aegypti and Aedes albopictus
  • States that the distribution of these species is largely driven by both human movement and the presence of suitable climate
  • Uses statistical mapping techniques to show that human movement patterns explain the spread of both species in Europe and the United States following their introduction
  • Finds that the spread of Ae. aegypti is characterized by long distance importations, while Ae. albopictus has expanded more along the fringes of its distribution
  • Describes these processes and predict the future distributions of both species in response to accelerating urbanization, connectivity and climate change
