Norwalk-like viruses or NLV) are members of the family Caliciviridae
and are well-recognized etiologic agents of nonbacterial AGE (5).
NoVs belong to the family Caliciviridae
and can be grouped into at least 5 genogroups (GI-GV), which are further divided into at least 35 genotypes (2,10).
Editorial Note: NLVs, previously known as small round-structured viruses, are the most common cause of nonbacterial gastroenteritis outbreaks in adults [1,2] Classified in the family Caliciviridae
[1,2], NLVs are transmitted by the fecal-oral route and have been implicated in 42%-7l% of viral outbreaks associated with contaminated water and food since the Norwalk virus was identified [1,3,4].
1 NoV strain; it belongs to the Caliciviridae
family of positive-sense, single-stranded RNA, nonenveloped viruses (3).
To the Editor: Human sapoviruses belong to a group of viruses within the family Caliciviridae
, which also includes noroviruses, that cause acute gastroenteritis (1).
Human sapovirus (SaV), family Caliciviridae
, is a causative agent of gastroenteritis in children and adults.
Classified into the genus Norovirus within the family Caliciviridae
, noroviruses are a genetically diverse group of nonenveloped, single-stranded RNA viruses, comprising at least 5 genogroups (GI-GV) and >35 genotypes (6).
The family Caliciviridae
consists of 5 genera, Norovirus, Sapovirus, Lagovirus, Vesivirus, and Nebovirus, and 3 proposed genera, Recovirus, Valovirus, and chicken calicivirus (8-10).
Norovirus and sapovirus are separate genera of the family Caliciviridae
