The white-throated woodrat is endemic in parts of Mexico and the western United Stated, while the deer mouse is also an inhabitant of the USA. Like other Peromyscus species, the deer mouse is a known vector and carrier of emerging infectious diseases, such as hantaviruses, Lyme disease and Sin Nombre Virus.
Brown or Norvegian rats (Rattus norvegicus), trapped in New York City during a one-year period (2013), were infected with numerous species of bacteria and viruses. One of these viruses was a previously unknown Pegivirus, tentatively named as Norvegian rat Pegivirus (or NrPGV).
The genetic diversity of the rodent hepaciviruses exceeded that observed for hepaciviruses infecting either humans or non-primates, leading to new insights into the origin, evolution, and host range of hepaciviruses.
