Inferred cross-species transmission events among the hantaviruses.

Note: The cross-species transmission events listed in this table were inferred by comparing the host (mt-cyt b) and virus (S, M, and S+M segment) phylogenies and looking for patterns of incongruence (Figure 5, Figure S4; Table S5).nt (nucleotide); aa (amino acid).+Compared with other hantaviruses, virus pairs shared the highest similarities in the nt and aa sequences of their S and M segments.
