PERFORMANCE: Greater Manchester West Mental Health Foundation Trust saw a “significant” increase in norovirus cases in 2012-13 – in line with the national trend.

The trust had 13 cases where wards were closed due to outbreaks of diarrhoea and vomiting, eight of which were confirmed as norovirus. There were seven other cases which did not lead to ward closures.

The worst month for outbreaks was August when six wards were closed for up to seven days, the annual report of the director of infection prevention and control revealed.
