Climate change is expected to alter the geographic and seasonal distributions of existing vectors and vector-borne diseases [Likely, High Confidence].

Rising temperatures, changing precipitation patterns, and a higher frequency of some extreme
weather events associated with climate change will influence the distribution, abundance, and prevalence of
infection in the mosquitoes that transmit West Nile virus and other pathogens by altering habitat availability
and mosquito and viral reproduction rates [Very Likely, High Confidence].
