Abstract

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.
