A bipartite network model connecting viral sequence clusters to their hosts supports these results, illustrating that bat CoVs were connected to several host families in Africa and Asia while being largely restricted to a single bat family in Latin (Fig. 4, Panel B) . Further, host switching was nearly four times more likely than virus sharing in Africa, when compared with Latin America (OR: 3.858; P ¼ 0.040). CoVs in Asia were also more likely to host switch than share when compared with Latin America, however the results were not significant (OR: 2.474; P ¼ 0.143). No particular bat family was associated with increased host switching, but this may reflect small sample sizes when the data are summarized by family.
