PEOPLE in Wirral are being urged to be extra vigilant this winter as last year's figures reveal a five fold increase in the norovirus cases across the north west compared to 2005.

NHS Wirral and Wirral University Hospitals NHS Foundation Trust are urging people to be vigilant and to look out for symptoms of norovirus - so that it is kept at bay.

Norovirus is often called 'winter vomiting disease' because it usually occurs during the winter months.

Cases usually start to appear during the autumn, peaking in the new year.

The virus thrives in semi-crowded environments where large numbers of people meet, so schools, care homes and hospitals are often affected.

If the infection is brought into hospital it can result in wards needing to be closed and impacting on hospital services.

There is no specific treatment for norovirus, apart from letting the illness run its course. It is important to drink plenty of fluids to prevent dehydration, especially in older and younger people.

Teresa Owen, Consultant in Public Health for NHS Wirral, said: "To avoid spreading the norovirus or similar vomiting disease, I would advise anyone with symptoms to stay at home and allow the condition to run its course.

"In most cases, the symptoms will stop after two or three days.

"It is important to remember that careful hand washing is the most important prevention measure that you can take.

"Before eating and after using the toilet, wash your hands thoroughly with soap and warm water and dry them afterwards. This will help to keep your friends, family and other loved ones healthy."
