NorovirusLauren WilliamsonNorovirus is a common virus that often affects many people. Norovirus is part of the Caliciviridae family. It is a non-enveloped, single-stranded RNA virus (1). There are three different genogroups of Noroviruses that infect humans. These are GI, GII and GIV. There are also many genotypes of Norovirus (2). More research is underway on this virus due to the discovery of new strains (1). The great genetic diversity of Norovirus is caused by errors in RNA replication and recombination between associated RNA viruses (2). Norovirus genogroups I and II are the most common cause of gastroenteritis worldwide and in all ages (2). GII-4 has been found to be the most prevalent Norovirus strain worldwide (1). Norovirus outbreaks commonly occur in elderly homes or hospitals, but can also occur in schools, on cruises, or any place that serves food (2). Many epidemics have been associated with the presence of shellfish, such as oysters, in contaminated waters (3). Norovirus is often transmitted through physical contact from a person ...
