context_page_description: Yokose virus is in the genus Flavivirus of the family Flaviviridae. Flaviviridae are often found in arthropods, such as mosquitoes and ticks, and may also infect humans. The genus Flavivirus includes over 50 known viruses, including Yellow Fever, West Nile Virus, Zika Virus, and Japanese Encephalitis. Yokose virus is a new member of the Flavivirus family that has only been identified in a few bat species. Bats have been associated with several emerging zoonotic diseases such as Ebola and SARS.
context_section_description: Yokose virus is in the genus Flavivirus of the family Flaviviridae. It was identified in 1971 in Yokosuka, Kyushu Island, Japan. The strain Oita-36 was isolated from bat species Miniopterus fuliginosus. Molecular genetic analysis has shown that Yokose virus is a new member of the Flavivirus genus. Flaviviruses are typically divided into three groups: mosquito borne, tick borne, or non-vector. Yokose virus is classified as NKV, or no-known vector. This means that it has no known arthropod vector. However, there is some evidence suggests that it may infect arthropods, namely being mediated by mosquitos. Yokose virus has been found to be genetically close to Yellow Fever virus with amino acid sequences showing close identify to Entebbe Bat virus.
