More patients have been struck down with vomiting bug norovirus this year compared with the previous five years, according to official figures.
Data from Public Health England shows reports of the bug had reached 2,435 this winter – 12% more than the average for the same period over the last five years. The figure is also 71% higher than the same period last year, although last winter had unusually low levels of norovirus.
In the week ending on Christmas Day, the outbreaks of vomiting and diarrhoea resulted in more bed closures than during the same period last year – rising from an average of 559 beds closed per day to 699. Hospitals reported 20 outbreaks of norovirus in the first two weeks of December, 17 of which led to bay or ward closures and 13 of which were confirmed as the bug.
In total so far this season, there have been 163 hospital outbreaks reported.
Nick Phin, deputy director of the national infection service at PHE, said: “Norovirus is a common cause of illness during winter. Exactly when the peak in activity occurs will be different each winter but levels seen so far this year are not unexpected compared with the previous five years.”
The number of laboratory reports of the bug rotavirus this season is 1,136, which is also 3% higher than the average for the period from 2003 to 2013.
In early November the Mexican restaurant chain Wahaca closed several branches in London after more than 350 customers and staff fell ill with suspected norovirus. PHE and environmental health officers were called in after the suspected outbreak of the winter vomiting bug struck at nine restaurants.
NHS England also released figures showing there were 291,808 calls to the NHS 111 service in the week ending on Christmas Day as temperatures plummeted and a cold weather alert was issued. This was nearly 9% lower than the number of calls to the helpline in the same week last year. Of calls answered, 93.2% were answered within 60 seconds and 1.5% of patients abandoned their calls after waiting 30 seconds.
