We enrolled 25 case farms (cases March-November 2007) and 75 control farms (June-November 2007). We used a questionnaire to collect farm data, which were analyzed by matched-pair analysis and multivariate conditional logistic regression. Factors independently associated were offering slaughter remnants of purchased chickens to backyard chickens (odds ratio [OR] 13.29, 95% confidence interval [CI] 1.34-131.98, p = 0.027), having a nearby water body (OR 5.27, 95% CI 1.24-22.34, p = 0.024), and having contact with pigeons (OR 4.47, 95% CI 1.14-17.50, p = 0.032). Separating chickens and ducks at night was protective (OR 0.06, 95% CI 0.01-0.45, p = 0.006). Reducing these risks and taking protective measures might reduce the risk for influenza (H5N1) infection in backyard chickens. | Source Title: | Emerging Infectious Diseases | URI: | https://scholarbank.nus.edu.sg/handle/10635/181000 | ISSN: | 10806040 | DOI: | 10.3201/eid1512.090643 | Rights: | Attribution 4.0 International |
