This is, however, not an easy task. As the authors reveal, there are 27 terrestrial mammal orders and large species richness. Tracking all the species even in a designated hotspot area would be difficult at best. The only way to approach this would be to examine those with at least some potential interaction with humans. Specific orders of highest risk would include rodents, bats, and carnivores. This may seem obvious but that is only due to the emergence of potentially preventable outbreaks.
