Climate change and viral emergence: evidence from Aedes-borne arboviruses

•Climate change is likely to increase global incidence of mosquito-borne viruses.•Outbreaks of disease caused by Aedes-borne arboviruses have been more frequent and more intense in recent years.•Current evidence suggests that climate could be partially driving recent outbreaks across the world.•More longitudinal analyses are needed at the local level to better understand climate's impact on arbovirus transmission.•Recent studies in Cordoba, Argentina, could be useful for understanding arbovirus emergence globally. Climate change is leading to increases in global temperatures and erratic precipitation patterns, both of which are contributing to the expansion of mosquito-borne arboviruses and the populations of the mosquitos that vector them. Herein, we review recent evidence of emergence and expansion of arboviruses transmitted by Aedes mosquitos that has been driven in part by environmental changes. We present as a case study of recent work from Córdoba, Argentina, where dengue has been actively emerging in the past decade. We review recent empirical and modeling studies that aim to understand the impact of climate on future expansion of arboviruses, and we highlight gaps in empirical studies linking climate to arbovirus transmission at regional levels.
