<unk>  <unk>  is a rodent-associated flavivirus. Small and enveloped,<unk>  contains positive single-stranded RNA. Taxonomically,<unk>  is part of the Flavivirus genus and Flaviviridae family. The Flavivirus genus includes nearly 80 viruses, both vector-borne and no known vector (NKV) species. Known flavivirus vector-borne viruses include Dengue virus, Yellow Fever virus, tick-borne encephalitis virus, and West Nile virus. In 1958,<unk>  was first isolated from the mammary gland tissue of a white-footed deer mouse (Peromyscus maniculatus) captured in<unk>  County, California. Since the first isolation, the<unk>  has also been isolated from deer mice in Oregon, Colorado, and Montana. There are other anti-genetically and genetically related viruses which also have no known vector such as Jutiapa virus, the Cowbone Ridge virus, the Sal Vieja virus, and the San Perlita virus. Little information is known about these viruses as well.
