The winter vomiting bug has struck early this year with cases running at a level normally seen about a month later in the season.
Figures released today show that 1.018 million have been hit with the vomiting sickness this winter.
Laboratory tests by the Health Protection Agency (HPA) have confirmed 3,538 cases of norovirus this season (from week 27 to week 50 2012), up from 3,046 cases last week.
The latest figures are 83 per cent higher than the number of cases reported at this point last year when there were 1,934 cases.
As most samples sent for analysis come from care homes and hospitals, officials work on a ratio of one laboratory case probably means there are a further 288 cases among people who do not seek medical treatment and are not tested.
