Abstract
Controlling Highly Pathogenic Avian Influenza, Bangladesh
Highlights
We focused on understanding the inter-relationships among household poultry producers, commercial farmers, suppliers, transporters, processors, and consumers that facilitate the process of producing and moving poultry, i.e., the entire poultry value chain (PVC)
To determine whether interventions would reduce the number of Highly pathogenic avian influenza (HPAI) infections, we implemented changes during 2009–2010 in 2 districts in Bangladesh, Gazipur and Dinajpur, that had a high number of cases
The results indicated that awareness of the proper disposal of birds that were culled or died because of HPAI had increased in both districts (p
Summary
To the Editor: Highly pathogenic avian influenza (HPAI) A(H5N1) virus is a deadly zoonotic pathogen. We describe how improved biosecurity on poultry farms and hygienic standards in live bird markets can reduce HPAI outbreaks. To determine whether interventions would reduce the number of HPAI infections, we implemented changes during 2009–2010 in 2 districts in Bangladesh, Gazipur and Dinajpur, that had a high number of cases (online Technical Appendix Figure 2). We created biosecurity improvement models (e.g., farm boundary, footbath) in 12 commercial farms in Gazipur and selected 2 live bird markets in each district for infrastructure improvements, including biogas and compost plants, that were needed for the cleaning and disinfection activities (online Technical Appendix Figure 3). Fewer HPAI outbreaks were reported and no clusters of infection were found during our intervention, 2009–2010 (online Technical Appendix Figure 1), probably indicating that control measures were effective.
