Highlights modifiable FMD transmission risks via equipment and movement; leaves open prospective validation of targeted controls.
Case-Control (n=281)
What are the risk factors associated with foot-and-mouth disease transmission between cattle and pig farms during the 2010 outbreak in Japan?
Odds Ratio: 9.6 (95% CI 1.1–80.2)
p-value: p=0.04
Physical barriers protect against FMD spread in movement restriction areas, while controlling people and vehicle movement is critical in shipment restriction areas.
Muroga et al. (2013) conducted a case-control in Foot-and-mouth disease (n=281). Sharing farm equipment with other farms vs. Not sharing farm equipment was evaluated on FMD transmission (infection status of the farm) (OR 9.6, 95% CI 1.1-80.2, p=0.04). Sharing farm equipment (OR 9.6), visits by feed transport vehicles (OR 5.1), and commuting farm staff (OR 20.0) were significant risk factors for FMD transmission between farms.
