A man in Scotland has become the first person to be made critically ill by swine flu alone.
The 45-year-old man, who is from Paisley, is receiving treatment in intensive care at Royal Alexandra hospital in Renfrewshire.
Another woman, who is 38 is also critically ill with swine flu and underlying health problems at the same hospital.
A 37-year-old man who last week became critically ill with H1N1 influenza A and other underlying problems is still receiving treatment in Glasgow’s Victoria Royal Infirmary.
In total, there have been 23 new cases of swine flu in Scotland today, bringing the total to 65.
Of the new cases, 14 are in the NHS Highland area, six are in Greater Glasgow and Clyde, two are in Ayrshire and Arran and one is in Lothian.
Scottish health secretary Nicola Sturgeon said the government was still pursuing a containment strategy, where officials trace contacts for all probably and confirmed cases to slow the spread of infection.
But she warned: ‘We’re getting closer now to a situation where the containment strategy we have been pursuing up until now will evolve into something different.
‘We are now seeing sporadic cases in the community, with clusters taking place around them.
‘Therefore the message to the public is to be vigilant and alert and, crucially, to follow key hygiene advice, which becomes even more important now.’
The total number of patients newly confirmed with swine flu across the UK is 63, bringing the UK total to 339.
A total of 282 cases are currently under laboratory investigation in the UK under the authority of the Health Protection Agency.
