6. Materials and methods.
Regional epidemiologists in England, and public health colleagues in Wales,
were contacted in Autumn 1999 and invited to participate in the
Campylobacter Sentinel Surveillance Scheme, which was due to commence
in April of the following year. This invitation was disseminated to Health
Authority-based Consultants in Disease Control, who then agreed or declined
to participate. The following health authorities agreed to participate:
Yorkshire and the Humber
o Bradford; Leeds
North West
o Bury and Rochdale; Manchester; North Cumbria; North West
Lancashire; Salford and Trafford; South Lancashire; Stockport;
West Pennine; Wigan and Bolton
West Midlands
o Birmingham; Herefordshire
East Midlands
o Leicestershire; Nottingham
Eastern England
o North Essex
London
o Barnet, Enfield and Haringey
South East
o East Kent; Southampton and South West Hampshire
South West
o South and West Devon
Wales
o Bro Taf; Dyfed Powys
Each NHS region in England at that time was represented, although a
greater proportion of health authorities in the north of the country were
represented. The sentinel population was broadly representative of England
and Wales as a whole (table 2, overleaf). The only major difference between
health authorities which participated and those which did not was the degree
of urbanisation, where a greater proportion of the sentinel population resided
in less sparse urban areas. Indian and Pakistani communities were also
slightly over-represented.
