Health bosses are warning of the dangers of a winter vomiting virus.
Norovirus, which has so far affected 50 people across Bedfordshire this year, causes vomiting, diarrhoea, a raised temperature and aching limbs.

The Health Protection Agency has warned people to isolate themselves until they have recovered fully, and not return to work, school or college until they have been free of symptoms for at least 48 hours.

Dr Joe Kearney, director for the Health Protection Agency in the East of England, said: "Norovirus infection is the most common cause of gastroenteritis in the UK, affecting between 600,000 and 1million people every year.

"Because it is more commonplace at this time of year it is sometimes referred to as winter vomiting.

"Unfortunately there is no specific treatment for norovirus apart from letting the illness run its course- there fore it is important to drink plenty of fluids to prevent dehydration, especially in the very young or elderly.

"Most people recover without any treatment other than rest and taking plenty of drinks to replace lost fluids."

Norovirus is known to spread rapidly in close-knit communities such as schools, workplaces and residential care homes.

The agency has advised people suffering from the virus to avoid food preparation until 48 hours after their symptoms have stopped.

Dr Keaney added: "Good hand hygiene practice at all times, especially after visiting the toilet is key to stopping the spread.

"Hands should be washed thoroughly in warm soapy water.

"Towels and flannels should not be shared with people who are unwell.

"Work surfaces and areas that have been contaminated by vomit should be thoroughly cleaned."

Anyone who has the symptoms should stay indoors and contact their GP or NHSDirect for further advice on 0845 46 47.
