Noroviruses are important causes of infective foodborne gastroenteritis.
The noroviruses (former called Norwalk virus), members of the Caliciviridaefamily, are pathogens with a world wide distribution. Due to the induction of short-term immunity, the human population is very susceptible to infections with these viruses. Outbreaks of norovirus gastroenteritis are typically caused by food and drinking water contaminated with faeces or sewage.
