The study provides an updated and comprehensive map of the global distribution of two major arbovirus vectors, *Aedes aegypti* and *Aedes albopictus*. These mosquitoes are responsible for the transmission of dengue and chikungunya viruses, which have become significant public health concerns due to their rapid global spread and increasing disease burden. The researchers compiled the largest contemporary database for both species and used it to predict their global distribution, incorporating environmental variables such as temperature, precipitation, and vegetation cover. The maps show that the distributions of these mosquitoes have expanded to include all continents, including North America and Europe, marking the widest distribution ever recorded. The findings highlight the need for rigorous entomological baseline data to project future health impacts of these viruses and inform public health planning. The study also discusses the factors influencing the distribution of these mosquitoes, including temperature, precipitation, and urbanization, and suggests that further research is needed to understand the rapid expansion of their range and potential control measures.The study provides an updated and comprehensive map of the global distribution of two major arbovirus vectors, *Aedes aegypti* and *Aedes albopictus*.
