Part Description

LP90134-5   Norovirus genogroup I
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.[https://www.cdc.gov/norovirus/preventing-infection.html] Source: Regenstrief LOINC

Change Reason
Believe this is reported as positive/negative; Noroviruses were previously called Norwalk, or Norwalk-like viruses. Updating from Norwalk virus to more widely accepted Norovirus naming convention as well as using the preferred name 'Norovirus Genogroup I' instead of 'Norovirus 1'; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
