The hospital norovirus outbreak reporting scheme (HNORS) recorded 28 outbreaks occurring between weeks 40 and 43, 2016, 25 of which led to ward/bay closures or restriction to admissions and were recorded as laboratory-confirmed due to norovirus. Between week 1 (week beginning 4 January 2016) and week 43 (week beginning 24 October 2016) 399 outbreaks were reported. Ninety-six per cent (384) of reported outbreaks resulted in ward/bay closures or restrictions to admissions and 79% (304) 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.
