Norovirus (Norwalk-like Virus, Small Round Structured Virus/SRSV)

Norovirus is the most common cause of infectious gastroenteritis in England and Wales. Although relatively mild, norovirus illness can occur at any age because immunity to it is not long-lasting. The disease was historically known as 'winter vomiting disease' due to its seasonality and typical symptoms. Outbreaks of norovirus gastroenteritis are common in semi-closed environments such as hospitals, nursing homes, schools and cruise ships.
