Figure 1. Current weekly norovirus laboratory reports compared to weekly average 2006/2010

 

In the current season to date † (from week 27, 2013, to week 26, 2014), there were 4654 laboratory reports of norovirus. This is 47 per cent lower than the average number of laboratory reports for the same period in the seasons between 2007/08 and 2011/2012 (8830)*. The number of laboratory reports in the most recent weeks will increase as further reports are received.


† The norovirus season runs from July to June (week 27 in year one to week 26 in year two) in order to capture the winter peak in one season.
* Last season 2012/2013 the season began earlier than normal so comparisons between this current and last season would not be valid.
