Abstract: In order to assess the spread risks of highly pathogenic avian influenza, a risk assessment framework was built on the thorough analysis of many related risk factors. In the process, analytic hierarchy process was used as the basic method in weighting the risk factors. The completed framework includes risk factor system, standards for risk assessment, weights of risk factors, integrated assessment methods and data collection.

Key words: highly pathogenic avian influenza, risk factor, risk assessment framework, analytic hierarchy process (AHP), weights, integrated assessment
