Establishment of Aedes aegypti (L.) in mountainous regions in Mexico: Increasing number of population at risk of mosquito-borne disease and future climate conditions
First time record in the state of Veracruz of Ae. aegypti at an elevation of 1420 m a.s.l. Entomological survey showed differences in mosquito species assemblages between rural and urban areas. Ae. aegypti was found now at higher elevations, exposing more people to dengue transmission. The return and emergence of dengue is driven by habitat destruction and biotic homogenization. Our monitoring reveals a climate change signal that could increase transmission risk in currently temperate areas.
