Overview
Norovirus is the cause of norovirus infection. Noroviruses (genus Norovirus) are a group of related, single-stranded RNA, nonenveloped viruses that cause acute gastroenteritis in humans. Noroviruses belong to the family Caliciviridae.

Life Cycle
Norovirus has a cytoplasmic replication. It attaches to the host receptors and enters the cell through endocytosis. Since, it is a positive sense virus, replication and transcription follows the corresponding models for positive stranded RNA viruses. Translation occurs by leaky scanning, and RNA termination-reinitiation.[1]
