Norovirus

Norovirus is positive sense single stranded RNA ,is the prototype of a family of unclassified small round structured viruses, which may be related to the caliciviruses. Commone illness caused by the Norovirues are viral gastroenteritis, acute nonbacterial gastroenteritis responsible to cause food poisoning, and food infection.Foods such as raw oysters, cake frosting and salads, as well as drinking water, have been implicated as a common source of viral infection in several outbreaks.According to CDC report norovirus stand in top pathogen responsible to illness and hospitaliztion .

Organism Details:
Shape and Size

Genome Information
Norovirus virus is a non enveloped positive-strand viruses ( GI:-106060735) has a 7654 bp single stranded linear RNA.The genome structure consists of 3 genes and 3 proteins.The GC content of Norovirus is about 48.0%.
Food Source
raw oysters/shellfish, water and ice, salads, frosting, person-to-person contact,Meat and Meat Products,Fish and Fish Products Water and Beverages Delicatessen Cereals Fish and Fish Products Water and Beverages
Pathological Factor
Norwalk virus was the first gastroenteritis virus reported to be food borne. This group of viruses has recently been classified as members of the calicivirus family. The term "small round structured viruses" (SRSV) was originally applied to these agents owing to their appearance under the electron microscope. NLV are difficult to detect, especially from foods.
Disease
Human norovirus is a major food and waterborne pathogen that causes acute gastroenteritis. The virus is transmitted primarily through the Gastroenteritis, Conjucntivitis,
