The National Offender Management Service (NOMS) receives from each prison in England and Wales a weekly report on the number of swine flu cases. To date there have been 130 cases confirmed by laboratory analysis since 13 July when data collection began.
The data shows that NOMS' strategy for managing swine flu in prisons has been effective in preventing the spread of swine flu among prisoners.
These data have been drawn from administrative information technology systems. Although care is taken when processing and analysing returns the detail is subject to the inaccuracies inherent in any large scale recording system. The data are not subject to audit.
