The number of confirmed cases of swine flu in the UK has reached 909, Health Secretary Andy Burnham has said.

In a statement to the Commons, Mr Burnham said 28 people had been admitted to hospital and that most of those had made a full recovery.

He said: “We recognised from the outset that we would be unlikely to prevent a widespread outbreak indefinitely.”

The UK had enough anti-viral drugs for 50% of the population and planned to raise that figure to 80%, he added.

Mr Burnham said people should not change their day to day behaviour and follow hand hygiene guidelines.

The World Health Organization has declared a pandemic following a sharp increase in the number of cases in Australia.
