Figure 2. Choropleth maps of A) the unadjusted prevalence and B) the empirical Bayesian-smoothed prevalence of Echinococcus multilocularis tapeworms in coyotes and foxes across 25 southern Ontario public health units, 2015–2017. Unadjusted and smoothed prevalence estimates are categorized by quartiles on the basis of unadjusted prevalence estimates. Red boundaries indicate a significant spatial cluster of high prevalence identified by using a spatial scan test with a Bernoulli model on the basis of data georeferenced to their public health units (relative risk 2.26; p = 0.002).
