(a) Counties our climate-constrained niche model identifies as potentially endemic (with a mean annual temperature greater than or equal to 10.7°C and a mean annual precipitation level less than or equal to 600 mm yr−1) for our baseline time period from 2000 to 2015 are colored in purple. (b) The estimated levels of valley fever incidence (cases per 100 000 population per year) for our baseline time period. We calculated these values by applying our OLS model to annual climate conditions from 2000 to 2015 and taking the mean incidence across the 16 years.
