Viral Zoonotic Risk Is Homogenous among Taxonomic Orders of Mammalian and Avian Reservoir Hosts

Do some reservoir groups (e.g. bats) produce more zoonotic viruses than others? By cataloguing the accepted reservoirs for 415 viruses associated with mammals and birds, we show that there is currently no evidence for the existance of any such special reservoir groups. Instead, groups containing more reservoir species are associated with more viruses, and proportionally more zoonotic viruses.

The role of viral evolution in rabies host shifts and emergence

Despite its ability to infect all mammals, Rabies virus persists in numerous species-specific cycles that rarely sustain transmission in alternative species. The determinants of these species-associations and the adaptive significance of genetic …
