It comes as new data from NHS England shows hospital norovirus cases remain close to the record high seen last week, with an average of 1,134 patients per day in hospital compared to 1,160.
Its data shows the recently emerged GII.17 genotype of norovirus has seen a surge in cases this winter but a different, commonly seen, genotype - GII.4 - is now on the rise.
Meanwhile, the UKHSA lab data - representing a fraction of cases in the community - show confirmed cases in the two weeks from February 3 to 16 were 29.4% higher than the previous fortnight and more than double the five-season average for the same period.
Amy Douglas, lead epidemiologist at the UKHSA, said: "Norovirus levels are still exceptionally high and now with multiple genotypes spreading at the same time, people could end up getting infected more than once this season.
The UKHSA reassured people that there is no indication that either GII.17 or GII.4 leads to more severe illness but said it is unclear whether norovirus cases have peaked for this winter.
