Norovirus is a common cause of infectious gastroenteritis that results in diarrhoea and vomiting. As its most common during the winter months, norovirus is sometimes known as the winter vomiting bug, but infections can occur at any time of year.

NHS boards report all ward and bay closures due to norovirus to us, including number of patients and staff affected and length of outbreak. These figures are added to an ongoing dashboard with figures by board and date.
