This coincidence indicates the importance of detailed contact investigations before pneumonic plague cases are declared linked in areas with ongoing epizootics.
The transmission and maintenance of RABV in natural populations of D. rotundus bats remains poorly understood, particularly within ongoing epizootics and enzootics occurring in different regions of the Americas (5, 6 ).
The great seroprevalence in skunks and raccoons trapped from Martha's Vineyard demonstrates an ongoing tularemia epizootic.
Overall, our data support the previous findings of Weaver et al. (5, 20 ) and provide new insights into the ecologic and evolutionary dynamics of an ongoing EEEV epizootic.
Given the implications of transmission heterogeneities on dynamics and control, more detailed studies are thus necessary to assess these heterogeneities when structuring control strategies in current and ongoing wildlife epizootics [13], [16], [22].
Multiple alignments were attained by using ClustalW (19 ) For phylogenetic reconstructions, we retrieved complete and partial RABV sequences from GenBank that represented historical and ongoing rabies epizootics in the Americas (Technical Appendix Table 2).
Continued surveillance and testing for H5N1 is warranted, given the current H5N1 epizootic, the ongoing occurrence of human H5N1 cases globally, and the importance of identifying influenza A viruses with pandemic potential in the United States as early as possible.
