From 2002 to 2017, we used these methods to determine how environmental conditions and surveillance practices are related to the presence of West Nile virus in mosquito traps throughout Ontario, Canada. Urban land cover and warm temperatures triggered viral occupancy, according to the study, which was more likely to result in a positive test for West Nile virus. Models with time-varying occupancy ratings met much lower Watanabe-Akaike information requirements than models without such effects.

Multiple extrinsic and intrinsic factors interact to influence transmission dynamics in nonlinear ways, so the effect of global climate change on infectious disease is highly debated. We found that drought, not within-season or winter temperatures, rather than precipitation directly. According to mosquito disease prevalence rather than mosquito abundance, drought epidemics may have arisened in one region, rather than mosquito abundance. We estimate that over the next 30 years, an increase in drought risk from climate change could triple West Nile virus infections, but only in regions with low human immunity.
