PUBLIC health officials have warned that flu is spreading increasingly rapidly in the West of Scotland and asked people not to visit patients in hospital if they are unwell.

The number of people turning to their GP with flu symptoms across Scotland is higher than usual this winter, linked to the fact the vaccine does not offer full protection against the main strain which is going around.

NHS Greater Glasgow and Clyde has had to close two hospital wards after a number of patients being treated developed flu. One at Gartnavel General has reopened but the second at Glasgow Royal Infirmary is still refusing new admissions.

The health board urged people who had suffered flu symptoms not to visit hospitals for at least 48 hours.

Dr Gillian Penrice, consultant in public health medicine for NHS GGC, said: "As the flu season sets in, it is important to be aware of the symptoms and act accordingly.

"Common symptoms of flu include fever, shivering, aching muscles and joints, tiredness and sore ears, which can see sufferers bed-ridden for several days.

"These signs are what make flu different from the common cold. In short, the infection begins suddenly and symptoms are more severe."

She added that there is a misconception that seeking antibiotics from a doctor will alleviate flu symptoms when this is not the case. .

Dr Penrice said: "Anyone who has flu-like symptoms does not need to seek medical help. Sufferers should drink plenty of fluids and take paracetamol to lower body their temperature.

"Local pharmacists can offer expert advice over the counter."

In the last four weeks the number of people turning to their GP for advice about flu symptoms has risen from 23.2 for every 100,000, to 45.4. This puts the rate of the illness higher than it has been at this time of year for the last four years. So far this winter 55 people have been admitted to intensive care in Scotland with complications from the illness and 15 have died.

The main type of flu spreading is known as influenza A H3N2 and it has changed or drifted from the strain of A H3N2 covered in this year's vaccine.

Most people are expected to recover from flu within a week, but if symptoms persist or get worse, they are encouraged to contact their GP. This is particularly important if patients are elderly or have long term health problems such as diabetes or asthma.
