FOUR people in Hertfordshire have tested positive for swine flu.

But health bosses are reassuring the public not to panic.

The confirmed cases - a family of three from Stevenage and a man from the west of the county - are all being treated at home.

Dr Jane Halpin, director of public health at NHS East and North Hertfordshire and West Hertfordshire, said: "The people here in Hertfordshire who have contracted swine flu have all spent time recently in a country affected by the virus and their symptoms are mild.

"They are all at home and being looked after by local GPs.

"There is no reason for members of the public to be concerned. We still have very few cases of swine flu and the symptoms are not severe."

Dr Halpin said the NHS had "robust plans" in place to tackle any potential spread of the virus.

"Our incident team meets regularly to review plans and to monitor the situation."

She added if anyone was concerned if they had been to Mexico, the US or any other affected country and had developed flu-like symptons, stay at home and contact your GP.
