A 37-year-old man critically ill in hospital probably has swine flu. The man was admitted last week to a hospital in Glasgow with a viral infection.

Scotland's Health Secretary, Nicola Sturgeon, said that it was "highly probable" he had the the virus, adding: "It is not yet known whether flu was the cause of his illness, or whether it was incidental to it."

An outbreak of swine flu at a school in the West Midlands saw the number of confirmed cases leap by 47 to 184, the Department of Health said. Of the new cases, 44 were linked to the school. The three other patients, from London and the East of England, were either returning travellers or people linked to previously confirmed cases.

The Health Protection Agency said the newly confirmed cases in the West Midlands involved 41 children and three adults. So far 170 cases of the H1N1 virus have been confirmed in England, with 13 in Scotland and one in Northern Ireland. Another 113 possible cases are being investigated.

A Department of Health spokesman said: "The localised cases of swine flu found in the UK have so far been mild, and we have not seen evidence of widespread community transmission."
