The family Caliciviridae comprises 11 genera (ICTV ratified in March 2019) of which viruses from the genus Norovirus and genus Sapovirus and a few rare strains in the genus Recovirus have been found in humans. Noroviruses are genetically classified into genogroups (G) which can be further divided into genotypes. Among noroviruses, viruses belonging to GI, GII, GIV, GVIII, and GIX (formerly GII.15) and among sapoviruses GI, GII, GIV and GV viruses infect humans.
