72% increase in norovirus cases
Around 100,000 people were struck down with the winter vomiting bug over Christmas, latest figures have suggested, as it emerged the number of confirmed cases was 72% higher than this time last year.
The dramatic rise was attributed in part to an early outbreak of the illness which closed dozens of hospital wards as it swept across the country.
A total of 3,877 laboratory-confirmed cases of norovirus have now been recorded in England and Wales - up on the 2,255 of last year. But the Health Protection Agency (HPA) said that for every reported case, an estimated 288 were not flagged up, meaning around 1.12 million people could have contracted the illness this season.
This is about 100,000 more than during the pre-Christmas period - until December 23 - when 1.01 million people were estimated to have come down with the bug. The number of reported cases dropped slightly during the Christmas week but this was in keeping with dips at the same time in previous seasons, the HPA said.
John Harris, an expert in norovirus from the HPA, said: "As we have seen in previous years there has been a dip in the number of confirmed laboratory reports owing to the Christmas and New Year period. However, in line with other norovirus seasons we will expect to see an increase in the number of laboratory reports in the next few weeks.
"Norovirus is very contagious, and anyone who has had it knows it is very unpleasant. If you think you may have the illness then it is important to maintain good hand hygiene to help prevent it spreading. We also advise that people stay away from hospitals, schools and care homes as these environments are particularly prone to outbreaks."
Cases of norovirus shot up earlier than expected this winter across Europe, but experts have been unable to determine why this is the case or predict whether numbers will continue to rise at the same rate. Symptoms - which usually last a few days - include sudden vomiting, diarrhoea, or both, a temperature, headache and stomach cramps.
A Department of Health spokesman said: "The NHS is well prepared for the winter. No A&Es have had to close so far this winter and we are providing additional funding to the NHS to help it cope with the added pressure that the winter brings.
"Flu and norovirus are typical at this time of year - that's why we are running the 'Catch It. Bin It. Kill It' campaign to remind people that one of the best ways to stop the spread of winter bugs is to Catch It, Bin It and Kill It when you cough or sneeze and wash your hands regularly.
"Our weekly published figures show the number of beds closed across the NHS due to norovirus symptoms is around 2.4%. This compares to 2.9% of beds that were closed during the peak of norovirus cases last winter."
