[Objective] To understand the status quo of foreigners infectious disease surveillance in Weihai Port, establish the risk assessment system for foreigners’ entry of infectious diseases and improve the level of quarantine supervision at the border. [Method] Risk analysis was conducted according to the DELPHI expert consultation method and the results of surveillance of infectious diseases of foreigners arriving in Weihai from 2000 to 2007, and the weight of each index was estimated by Saaty’s method. [Results] According to the principles of systematicness, scientificness, applicability and efficiency, the index structure of the project risk assessment system of infectious disease after entry of foreigners was determined, including the hierarchy and weight coefficient of the evaluation system. The assessment system includes three aspects of risk factors: source of infection, route of transmission and its influencing factors, prevention and control measures; 14 sub-risk factors including the global distribution of sources of infection. And the evaluation system has been put into practical application with good results. [Conclusion] It is feasible and scientific to establish the system of risk assessment of infectious diseases after foreigners entering the country using Delphi expert consultation and analytic hierarchy process, so as to clarify the key points of work and maintain the health and safety at the border crossings.
