Each reservoir was categorized by the orders of mammals represented by the species it included. Orders reflect the hierarchy detailed in Mammal Species of the World [22]. The data above show the percentage of systems whose reservoirs include at least one species belonging to the order. The number of systems is given in parentheses. Unlisted mammalian orders were not found among reservoirs.
*The epidemic potential zone subsets represent the transmission potential of the pathogen in the target host population(s) following spillover. The zones are defined as follows: dead-end for a basic reproductive number (R0) nearly equal to zero, stuttering chains for an R0 greater than zero but less than one, and epidemic potential for an R0 greater than one.
†High priority zoonotic pathogen subsets were determined by estimating the pathogen’s representation in the scientific literature using the H-index. Each subset was created to include pathogens that are among the 25% (Top 25%) and 10% (Top 10%) most significant known human pathogens.
