Abstract

Please cite this paper as: Gonzales et al. (2012) Rate of introduction of a low pathogenic avian influenza virus infection in different poultry production sectors in the Netherlands. Influenza and Other Respiratory Viruses DOI: 10.1111/j.1750-2659.2012.00348.x.

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.
