Noroviruses (genus Norovirus, family Caliciviridae) are a group of related, single-stranded RNA, nonenveloped viruses that cause acute gastroenteritis in humans. Norovirus was recently approved as the official genus name for the group of viruses provisionally described as "Norwalk-like viruses" (NLV). This group of viruses has also been referred to as caliciviruses (because of their virus family name) and as small round structured viruses, or SRSVs (because of their morphologic features). Noroviruses are named after the original strain "Norwalk virus," which caused an outbreak of gastroenteritis in a school in Norwalk, Ohio, in 1968.

Norovirus (NV) is a non-enveloped, single-stranded RNA virus that belongs to the Caliciviridae family. It was previously known as the 'Norwalk-like virus'. Of the six known genogroups of NV, only three are known to infect humans and include GI, GII, and GIV. Within these three genogroups 25 genotypes have been discovered, which is why people can be infected multiple times throughout their lives. Infection with NV causes inflammation of the stomach and intestines which leads to non-bloody diarrhea, vomiting, nausea, stomach pain, fever, headache, and body aches. Symptoms persist for 1-3 days, but NV can be found in stool samples of infected people for up to two weeks after symptoms subside. The virus is highly contagious and is transmitted by the fecal-oral route, by contact with infected people, and by contact with contaminated surfaces or substances. NV is the primary cause of food-related illness in the United States. The most common genotype of NV that is responsible for outbreaks since 2002 is GII.4. NV spreads quickly in closed spaces such as daycare centers, nursing homes, schools, and cruise ships. Diagnostic tests for NV include those that detect the viral RNA or a viral antigen in stool.[] Source: Regenstrief LOINC
