The Bunyaviridae is the largest family of RNA viruses, with over 350 isolates worldwide distributed into five genera (i.e., Hantavirus, Orthobunyavirus, Nairovirus, Tospovirus, and Phlebovirus). Many of these viruses are significant human or agricultural pathogens. The increasing number of reports on new emerging bunyaviruses and infection episodes makes it essential that we obtain a comprehensive understanding of bunyaviruses and their infection mechanisms. Although all bunyaviruses possesses a tripartite, negative-sense (or ambi-sense) RNA genome, they exhibit substantial differences in...
