What do studies in wild mammals tell us about human emerging viral diseases in Mexico?

ABSTRACT: Multiple species of viruses circulate in wild mammals, some of them potentially causing zoonosis. Most of the suspected viral zoonotic diseases affecting human patients remain unidentified with regard to their aetiological agent. The aim of this study is to summarize the state of knowledge of the viral richness associated with wild mammals in Mexico throughout 1900-2018 and their relationship with human cases. We compiled two databases, one of them containing all available published studies on potentially zoonotic viruses in wild mammals and another with human cases related to zoonotic viruses. The database on wild mammals covers the period of 1900-2018; the human case database spans 2000-2013. We calculated the richness of viral potential zoonotic agents and evaluated their geographical distribution. We found 262 records of 42 potential zoonotic viral species associated with 92 wild mammal species in 28 states across Mexico. Records of human viral cases were only found in 29 states, which did not overlap with the reports in wild mammals. We detected 25.6% (42/164) of viral zoonotic agents reported worldwide. This analysis opens a relevant topic of discussion for public health attention.
