Group of genetically-diverse single-stranded RNA viruses comprising the Norwalk virus, which can cause inflammation of the stomach and large intestine lining (gastroenteritis). Also known as Norwalk-like virus, "small, round-structured virus" (SRSV), Spencer flu, "Snow Mountain virus", "winter vomiting bug", and "stomach flu", but the latter refers to a range of viruses and bacteria.
Norovirus is a very contagious virus that can infect anyone, mainly by person-to-person contact or by contaminated food and water. Norvovirus (NoVs) is classified into at least five types (genogroup I [GI] to genogroup V [GV]) and 34 genotypes. Human NoVs are in GI, GII, and GIV. In addition, NoVs have been detected in pigs (GII), cows (GIII), mice (GV), large carnivores (GIV.2) and dogs (GIV.2) and can spread easily across a group of animals.
The virus causes your stomach or intestines or both to get inflamed. This leads you to have stomach pain, nausea, and diarrhea and to throw up. These symptoms can be serious for some people, especially young children and older adults.
