新会区甲型H1N1流感流行的风险评估

目的:研究新会区当前出现的甲型H1N1流感流行的风险,为制定科学有效的预防控制措施和策略提供依据。方法:通过对新会区甲型H1N1流感流行进行调查评估,根据调查结果确定甲型H1N1流感传播的风险因素。结果:对本区农村和城镇两个地区进行三次抽样调查,人群甲型H1N1流感总的抗体阳性率为22.29%,其中农村地区人群阳性率为25.83%,城区居民的阳性率为18.75%,各职业人群阳性率从高至低依次为:教师(33.33%)、医护人员(28.75%)、学生(22.57%)、其他人群(11.32%)、儿童(11.11%),居民对甲型H1N1流感的知晓率为42.91%,其中城镇居民明显高于农村居民。结论:通过分析当前新会区甲型H1N1流感情况,甲流病毒易传播的特点,人群抗体水平较低和人群对甲型H1N1流感的知晓率不高,预测甲型H1N1流感可能会再爆发,所以应确定流感大流行的高风险地区和最重要的风险因素,减少防控工作的被动性与盲目性,有针对性地采取预防控制措施。

Risk assessment of pandemic influenza A(H1N1) virus in Xinhui district

Objective: To evaluate the risk of influenza A H1N1 influenza epidemic in Xinhui district in order to make scientific and effective prevention and control measures and strategy.Methods:H1N1 influenza epidemic risk in Xinhui district were investigated and evaluated based on which H1N1 influenza transmission risk factors were analyzed.Results: Three sample surveys conducted in both urban and rural area of this part showed that total positive rate of influenza A H1N1 influenza antibody for populations of this area was 22.29%,specifically,for rural population it was 25.83% for city residents the positive rate was 18.75%.Regarding to occupation,positive rate for teachers,health care workers,students,children and other population were 33.33%,28.75%,22.57%,11.11% and 11.23%.The awareness rate for city residents was 42.91%,significantly higher than that of rural residents.Conclusions:The positive rate of influenza A H1N1 influenza antibody for populations of this area is low,and awareness is poor,thus outbreak of pandemic influenza is possible,and prevention and control measures are necessary.
