Global patterns of aegyptism without arbovirus

The objective in this study is to explore previously published global patterns in the environmental suitability forAe.aegypti and dengue virus to reveal deviations in the probability of the vector and human disease occurring. We developed a map showing one end of the gradient being higher suitability ofAe.aegypti with low suitability of dengue and the other end of the spectrum being equal and higher environmental suitability for bothAe.aegypti and dengue. The regions of the world withAe.aegypti environmental suitability and no endemic dengue transmission exhibits a phenomenon we term ‘aegyptism without arbovirus’. We then tested what environmental and socioeconomic variables influence this deviation map revealing a significant association with human population density, suggesting that locations with lower human population density were more likely to have a higher probability of aegyptism without arbovirus. Characterizing regions of the world with established populations ofAe.aegypti but little to no autochthonous transmission of human-amplified arboviruses is an important step in understanding and achieving aegyptism without arbovirus.
