An art teacher is among the latest confirmed cases of swine flu in Scotland, with 20 of her pupils and 10 colleagues now offered anti-viral drugs as a precautionary measure.

An art teacher is among the latest confirmed cases of swine flu in Scotland, with 20 of her pupils and 10 colleagues now offered anti-viral drugs as a precautionary measure.

The female teacher takes S6 pupils at St Andrews and St Brides High School in East Kilbride and also works as a volunteer at Universal Connections, a youth centre in Rutherglen.

Six pupils and one teacher at the school and 14 young people and nine staff at the youth centre have been given Tamiflu and told to stay away for a week.

The Scottish Government said the number of people suffering from the bug has risen to 508 in Scotland, after 10 cases of the virus were confirmed yesterday.

In East Renfrewshire, seven children between the ages of three and 12 have been diagnosed with the virus, as has a worker at the B&Q store in Darnley, Glasgow.

In Thornliebank, Glasgow, close to the home of Jacqueline Fleming, 38, who earlier this week became the first person in the UK to die from swine flu, a three-year-old child at Glenwood Nursery and a five-year-old pupil at Our Lady Of The Missions primary have been confirmed as cases.

In Newton Mearns, a five-year-old boy at St Cadoc's Primary has been diagnosed along with two S1 pupils at Mearns Castle High, and a further two 13-year-olds at Eastwood High also tested positive for the H1N1 virus.

The victims are among the 351 possible new cases seen by doctors in the Glasgow area over the last 24 hours. A further 10 patients from the city and its surrounds have been diagnosed following laboratory testing.

The schools in East Renfrewshire and South Lanarkshire will remain open as normal given that public health officials are no longer working to contain the virus in the Greater Glasgow area.

David Cromie, consultant in public health medicine at NHS Lanarkshire, said: "All parents and carers of the pupils and young people involved, as well as all parents and carers of pupils at St Andrews and St Brides, have been provided with advice and guidance on what they should do if their child develops flu-like symptoms.

"The school remains open and all other staff and pupils have been advised to attend as normal. Universal Connections also remains open."

Public health officials said that the decision to keep the schools open as usual was taken after a full risk assessment.

"Some schools may close but if the contact with other pupils has been limited then the chances of other children in the school developing the infection are extremely low and the school can remain open," a spokeswoman for Greater Glasgow and Clyde NHS said last night.

The mother of a St Cadoc's pupil said last night she would be keeping her son away from school for now. She added: I would like to see the school closed for at least a day."
