SHOOT: But don't panic, it's nothing unusual, carry on as normal sheep.
A third of the population may catch swine flu this winter and the virus could be here for up to five years, the government's medical chief has warned. But Sir Liam Donaldson told the BBC the deaths of people with no apparent health problems did not mean the virus was becoming more severe.
Seventeen people with swine flu have died in the UK so far.
Sir Liam, who is chief medical officer for England, said it was "too early to say" whether a mortality rate of one in 200 - as suggested by some experts - was accurate.
"We just haven't seen enough cases in this country to give an accurate figure.
The virus will not just be here for one winter - previous pandemics have been around three, four, five years

"But the longer it goes on - as the virus passes through more and more people - you do have to be alert to it changing. |
