Public health risk assessment of imported infectious diseases in Jinhua / 预防医学

ABSTRACT

Objective@#To carry out an assessment on the public health risk of imported infectious diseases in Jinhua, so as to provide evidence for prevention and control strategies.@*Methods @#Twenty-nine imported infectious diseases were recruited. A risk assessment index system was established by Delphi method and analytic hierarchy process. The actual values of each index of twenty-nine imported infectious diseases were obtained through special investigation,literature review and consultation. The risk scores were calculated by the improved technique for sequencing by approximate ideal solution (TOPSIS) and classified according to median.@*Results @#Among 41 experts recruited, 38 experts were engaged in infectious disease prevention and control, 31 had senior professional titles, and all had worked for more than 10 years. Through three rounds of consultation by Delphi method and analytic hierarchy process, the risk assessment index system (target level) included four items in criteria levels, which were response capacity, public health impact, the possibility of import and local transmission and population vulnerability in a descending order of weight; twenty-seven indicators, with international attention level, levels of medical institutions with confirmed cases, the emergency response capacity of Centers for Disease Control and Prevention (CDCs) , and effective vaccines with wide coverage weighed higher. There were eleven high-risk diseases, high response capacities lay in dengue, malaria, Zika virus disease and Chikungunya fever. The response capacities for sixteen of the eighteen low-risk diseases were insufficient, especially in emergency response capacity of CDCs, laboratory testing capacity and hospital infection control ability.@*Conclusion@#Jinhua has strong capacities to deal with the incidence of dengue fever, malaria, Zika virus disease and Chikungunya fever, compared with other imported infectious diseases.
