Christmas parties are causing the winter vomiting bug to spread rapidly as sufferers are attending while still infectious, warns a norovirus expert.
Ian Clarke, Professor of Molecular Microbiology and Virology at the University of Southampton, claims that people can remain contagious until three weeks after they have recovered.
Prof Clarke told MailOnline that patients going to parties where they are kissing and hugging others are almost certainly infecting more people.
Figures released on Tuesday show the number of people affected by the illness is 83 per cent higher than this time last year
He said: 'Some people secrete virus after their symptoms have elapsed.
'This can go on for up to three weeks but the amount gets less and less.'
New figures from Superdrug show that people are concerned about the problem – sales of anti-bacterial hand gel have increased 52 per cent this week compared to last week.
Figures released on Tuesday show the number of people affected by the illness is 83 per cent higher than this time last year due to an early outbreak of the virus.
Most cases usually occur from January to March, making this the worst start to the norovirus season on record.
The virus is showing no signs of abating, with the number of people affected almost doubling in the space of a week.
Dozens of hospital wards have been closed and holidaymakers on two cruise ships have also been affected.
IF YOU THINK YOU HAVE IT
The Health Protection Agency advises the following measures:
NOT visit your GP surgery or local A&E Unit. Norovirus infection is
a self-limiting illness and you will recover naturally without
treatment. It is, however, important to take plenty of drinks to replace
NHS Direct's new diarrhoea and vomiting online health and symptom
checker, to get advice on how to manage your symptoms at home or help to
access the most appropriate health service.
Wash hands thoroughly and regularly at all times, but particularly after using the toilet and before eating.
not visit friends or relatives in hospitals or residential care homes
as there is a real risk that you would introduce the infection, putting
vulnerable people at risk.
Figures released yesterday from the Health Protection Agency show there were 337 confirmed laboratory reports of norovirus in the week ending December 9 and 236 for the week ending 2 December – a rise of 42 per cent.
The number of confirmed cases – where samples have been checked in the lab – have risen from 1,669 to 3,046 this season.
But this figure is likely to be only a fraction of the true total as most sufferers do not see their GP. Officials at the HPA estimate that for every confirmed case there are another 288 in the community.
Hospital outbreaks are also double what they were this time last year. The HPA figures there were 61 hospital outbreaks during the last two weeks up to December 16. In same fortnight in the previous year there were 35.
Data from the Department of Health shows that 2,398 hospital beds are ‘closed’ due to norovirus – equating to 1 in 50 of all available beds.
Figures from Firstcare, which monitors absence rates, show that an average of 5,263 NHS staff are calling in sick with typical symptoms every day.
And during November some 128,800 working days were lost in the NHS due to employees being off with sickness.
It is estimated that 0.4 per cent of the 1.4million workers in the NHS are off sick with symptoms.
It is not known what proportion are frontline staff but they are likely to be in the majority, as they are mostly in contact with patients.
Sales of anti-bacterial hand gel have increased 52 per cent this week compared to last week
John Harris, an expert in norovirus at the HPA, said: 'The number of laboratory confirmed cases has risen again, following the drop in the number we reported last week.
'This is typical of the norovirus season where the number of laboratory reports fluctuates between October and April with the bulk of cases usually occurring between January and March.'
The Government's Chief Medical Officer Professor, Dame Sally Davies, said: 'For most people norovirus is an unpleasant but short lived illness. There is no specific treatment but patients are advised to drink plenty of fluids and stay at home.
HOW CAN I AVOID CATCHING NOROVIRUS
Wash your hands at least five times a day with soap and waterIf someone in your family gets it, protect everyone else by cleaning your bathroom with bleach-based cleanersAvoid food prepared by anyone who has had the virus within the last 48 hoursScrub your kitchen with bleach-based cleaning fluids
'Anyone who is concerned should call either NHS Direct or their local GP Practice for advice. Please avoid attending A&E as this could spread the illness to vulnerable people and healthcare workers.'
A Department of Health spokesperson added: 'The NHS is well prepared for the increase in winter related health problems which are typical at this time of year.
'Our weekly published figures show the number of beds closed across the NHS due to norovirus symptoms is around 2 per cent. This compares to 2.9 per cent of beds that were closed during the peak of norovirus cases last winter.'
