New papers on Aedes aegypti and Ae. albopictus
Two new papers by Kraemer et al, The global distribution of the arbovirus vectors Aedes aegypti and Ae. albopictus in eLife and The global compendium of Aedes aegypti and Ae. albopictus occurrence in Scientific Data focus on the compilation of the largest contemporary database for both species and pair it with relevant environmental variables predicting their global distribution.
The papers show the Aedes distributions to be the widest ever recorded; now extensive in all continents, including North America and Europe. These maps will help define the spatial limits of current autochthonous transmission of dengue and chikungunya viruses. It is only with this kind of rigorous entomological baseline that we can hope to project future health impacts of these viruses.
The data descriptor paper presents the global geographic database of known occurrences of Ae. aegypti and Ae. albopictus between 1960 and 2014, and describes the data collection processes, geo-positioning methods, database management and quality-control procedures.
