Risk Factors for Herd Breakdown with Post-Weaning Multisystemic Wasting Syndrome (PMWS) in Great Britain
K.A. Woodbine, G.F. Medley, J. Slevin, A.L.Kilbride, E.J. Novell, M.J. Turner, M.J. Keeling and L.E. Green
A retrospective cohort study of 116 British pig farms was undertaken to investigate the epidemiological risk factors for Post-weaning Multisystemic Wasting Syndrome (PMWS) in Great Britain (GB). Analysis of the spread of PMWS showed that PMWS occurred initially in the south of England, moving west and then northwards. The pattern of spread included long distance and local spread around infected farms, with strong evidence of non-random space-time clustering. Analysis of the main risks for introduction of PMWS indicated a change in the pattern of risk through time. Initially, farms were associated with the greatest risk of PMWS introduction if they had more than 600 sows and/or purchased gilts. During the Foot and Mouth Disease (FMD) epidemic, when animal movement restrictions were in place, the greatest risk of PMWS introduction was associated with farms with a grower/finisher herd in close proximity and/or where visitors were allowed onto farms that were less than 3 days pig-free. After FMD, PMWS introduction was associated with farms that had more than 600 sows, close proximity to an infected herd and/or when visitors were allowed onto farms that were less than 3 days pig-free.
