Abstract
Noroviruses (NoVs) are an important cause of acute viral gastroenteritis worldwide and affect humans in all age groups. Their transmission modes are food, person-to-person contact, and environmental contamination. NoVs are diverse genetically and classified into five genogroups (GI-GV). The GI and GII NoVs affect humans most commonly, causing infection every year. The genogroups are subdivided into more than 30 different genotypes. The GII.4 genotype has been the most commonly identified genotype worldwide in recent years. Specifically, the GII.4 variant caused the major epidemic of the 2006-2007 season. The present review focuses on recent findings in NoV infection relating to their transmission, epidemiology, and evolutionary changes. New knowledge improves our understanding of NoV infection and will be useful in control and prevention.
