We conducted a retrospective analysis of state-wide mosquito-borne virus and mosquito abundance data in Rhode Island from 2002 to 2022, finding that vector infection rates for eastern equine virus decreased in over time despite the major outbreak of EEE in 2019. WNV infection rates, in contrast, increased among important vectors. We analyzed the spatial, temporal, and spatiotemporal patterns of the vectors of Eastern Equine Virus (EEV) and West Nile virus (WNV), and compared models incorporating features of the landscape, climate, and built environment. In addition to estimating the impact of temperature and other climatic variables, our findings demonstrate that geologic history is an important context to consider landscape attributes such as elevation and groundwater level.
