To ask the Scottish Executive how many cases of influen'a have been reported this winter in each NHS board area; how many such cases are being treated in hospital; how many are of a new strain, and how many cases have resulted in deaths.
Influenza-likeillness is increasing in Scotland at present, and there is certainly more around than we haveexperienced in the last few years. Estimatesfrom the Scottish
InfluenzaSpotter Scheme co-ordinated by the Scottish Centre for Infection andEnvironmental Health now exceed the baseline threshold limit of 50consultations per 100,000 population. At 11 November 2003 the estimate was 99 per 100,000 population across Scotland asa whole. The consultation rate for “normal activity” for seasonal influenzalike illness is defined as between 50 and 600 consultations per 100,000population. As such we are still within the lower part of this range currently.
However, laboratoryanalysis is required to confirm a diagnosis of influenza. Laboratory data as at17 November, by NHS board, are shown in the table below (These respiratoryvirus laboratory data broadly reflect the NHS board areas. They are summationsof the laboratory detections from hospital and community samples. While the GPpractices are immediately attributable to NHS boards, the hospital laboratoriesto which samples are submitted are not necessarily the place of residence of theindividuals from whom the samples were obtained).

It is notpossible to indicate how many such cases are being treated in hospital ashospital data for this winter are not yet available centrally.
The UK nationalinfluenza laboratory is the only UK laboratory that tests for influenza strain type.Only a select number of the clinical isolates are routinely sent to thislaboratory for strain typing (for example, from patients who have died or fromoutbreaks in defined settings). The only Scottish cases to date in whichinfluenza A Fujian-411-2002-like virus has been identified have been in thethree reported deaths in children.
