Calculations say one million and 18,000 people have been hit with the vomiting sickness this winter, the Daily Telegraph reported on Friday.
Laboratory tests by the Health Protection Agency confirmed 3,538 cases of norovirus this season.
The latest figures are 83 percent 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 say 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.
Symptoms of norovirus include a sudden onset of vomiting and diarrhoea. Some people may have a temperature, headache and stomach cramps.
The illness usually resolves in one or two days and there are no long-term effects.
