The hospital norovirus outbreak reporting scheme (HNORS) recorded two outbreaks occurring between weeks 31 and 34, 2016, both of which led to ward/bay closures or restriction to admissions. No outbreaks were recorded as laboratory confirmed due to norovirus. Between week 1 (beginning 4 January 2016) and week 34 (beginning 22 August 2016) 367 outbreaks were reported. Ninety-seven per cent (355) of reported outbreaks resulted in ward/bay closures or restrictions to admissions and 80% (285) were laboratory confirmed as due to norovirus.

† The norovirus season runs from July to June (week 27 in year 1 to week 26 in year 2) in order to capture the winter peak in one season.
Note:the number of laboratory reports in the most recent weeks will increase as further reports are received. On 1 December 2014 a new laboratory reporting system was commissioned; as a result, direct comparisons between earlier reports (based on LabBase2) and the new system (SGSS) may not be valid.
