Classification
Noroviruses (NoV) are a genetically diverse group of single-stranded RNA, nonenveloped viruses belonging to the Caliciviridae family.[1] According to the International Committee on Taxonomy of Viruses, the genus Norovirus has one species, which is called Norwalk virus.[2] Serotypes, strains and isolates include:[3]
- Norwalk virus
- Hawaii virus
- Snow Mountain virus
- Mexico virus
- Desert Shield virus
- Southampton virus
- Lordsdale virus
- Wilkinson Virus.[4]
Noroviruses commonly isolated in cases of acute gastroenteritis belong to two genogroups: genogroup I (GI) includes Norwalk virus, Desert Shield virus and Southampton virus, and II (GII), which includes Bristol virus, Lordsdale virus, Toronto virus, Mexico virus, Hawaii virus and Snow Mountain virus.[1]
Noroviruses can genetically be classified into five different genogroups (GI, GII, GIII, GIV, and GV), which can be further divided into different genetic clusters or genotypes. For example, genogroup II, the most prevalent human genogroup, presently contains 19 genotypes. Genogroups I, II and IV infect humans, whereas genogroup III infects bovine species, and genogroup V has recently been isolated in mice.[4]
