The cross sectional study had been carried out in December 2005 at Kalimantan and Sumatera Island, Indonesia. The objective of this study was to apply the logistic regression model to identify the risk factor of H5N1 avian influenza virus of native chicken, 12,713 serum samples of chicken from 498 farmers was collected. The H5N1 virus was tested by Haemagglutination Inhibition (HI) test from serum samples and the information of risk factor was obtained from a questionnaire. The questionnaire included farmer's characteristic and farm management. Logistic regression model showed that an assodation with H5Nl virus infection risk at a 5% significance level was found for chicken house sanitation, feeding equipment sanitation, drinking equipment sanitation and chicken run sanitation. The multivariable regression analysis showed that an association with H5Nl virus infection risk at a 5% significance level was found for chicken house sanitation.
