Are Noroviruses emerging?
Today, noroviruses are recognized as the most common cause of infectious gastroenteritis among persons of all ages. They are responsible for around50% of all foodborne gastroenteritis outbreaks in the United States. Noroviruses have been detected in 35% of persons with sporadic gastroenteritis of known cause and in 14% of all children <3 years old hospitalized for gastroenteritis. However, a fundamental question remains—is the increased detection of norovirus the result of better application of improved diagnostics, or does evidence exist that norovirus disease is an emergent problem? Despite a lack of consistent retrospective data to definitively answer this question, several factors suggest that norovirus disease may actually be more common today. This paper reviews the evidence for this. Emerging Infectious Diseases 2005; 11: 735-737.
