Sapoviruses are caliciviruses that together with the Norwalk virus, are the most common cause of acute viral gastroenteritis in adults.[1] The type species is Sapporo virus[2] and it is named after Sapporo, Japan where the virus was first discovered following an outbreak of gastroenteritis in an orphanage.[3] Unlike norovirus, this virus generally only causes mild gastroenteritis in young children.[4]
Taxonomy
Sapovirus are currently classified into seven genogroups (GI to GVII) based on the complete sequence of capsid. GI, GII, GIV and GV are known to infect humans [5]
Animal viruses
Sapoviruses have been identified in bats, California sea lions, dogs, pigs and mink.[6][7]
