BACKGROUND
Targeted risk-based surveillance of poultry types (PT) with different risks of introduction of low pathogenic avian influenza virus (LPAIv) infection may improve the sensitivity of surveillance.
OBJECTIVE
To quantify the rate of introduction of LPAIv infections in different PT.
METHODS
Data from the Dutch LPAIv surveillance programme (2007-2010) were analysed using a generalised linear mixed and spatial model.
RESULTS
Outdoor-layer, turkey, duck-breeder and meat-duck, farms had a 11, 8, 24 and 13 times higher rate of introduction of LPAIv than indoor-layer farms, respectively.
CONCLUSION
Differences in the rate of introduction of LPAIv could be used to (re)design a targeted risk-based surveillance programme.
背景
对具有不同低致病性禽流感病毒（LPAIv）感染引入风险的禽类型（PT）进行靶向风险监测，可能会提高监测的敏感性。
目的
定量不同 PT 中 LPAIv 感染的引入率。
方法
使用广义线性混合和空间模型分析了荷兰 LPAIv 监测计划（2007-2010 年）的数据。
结果
户外层、火鸡、鸭饲养场和肉鸭养殖场的 LPAIv 引入率分别比室内层养殖场高 11、8、24 和 13 倍。
结论
LPAIv 引入率的差异可用于（重新）设计有针对性的基于风险的监测计划。
