Norovirus is known to cause acute gastroenteritis. It is a small (27-38 nm), round, nonenveloped RNA virus belonging to the Caliciviridae family and is responsible for over 80% of non-bacterial outbreaks of gastroenteritis in the world. It affects individuals of all ages, with a distinct seasonal link to winter. It has a genome of 7.6 kb that is positive sense and has a single stranded linear confirmation. It encodes a major structural protein (VP1) of about 58 to 60 kDa and a minor capsid protein (VP2). Transmission occurs predominantly through ingestion of contaminated water, food and airborne transmission, as well as contact with contaminated surfaces. The ease with which norovirus is transmitted and the low infectious dose required to establish an infection results in extensive outbreaks in numerous environments, such as hospitals, hotels and schools. There is no antiviral drug available to treat this infection and little is known about its pathogenicity. However, it has been observed that the virus can be taken up by enterocytes where translation of viral nonstructural proteins can occur; it damages and alters intestinal microvilli, leaving them blunt and broadened, thus inhibiting absorption; it causes crypt cell hyperplasia and also leads to apoptosis of enterocyctes. An incubation period of 24-48 hours is usual. Infection is characterized by the acute onset of nausea, vomiting, abdominal cramps, aching limbs, raised temperature and diarrhoea that generally last for about 48 hours. However, more severe and prolonged infection may be observed in children and the elderly. There are five recognized norovirus genogroups, of which three (GI, GII, and GIV) are known to affect humans and, since 2002, variants of the GII.4 genotype have been the most common cause of norovirus outbreaks. There have been 31 different genotypes identified within the genogroups, with a wide degree of genetic variability present even within each genotype.
