三峡库区重庆段2004年传染病流行病学分析

目的：分析三峡工程二期蓄水后的第1年，三峡库区重庆段三峡人群健康监测点传染病流行情况。方法：根据中国疾病预防控制中心《三峡人群健康监测方案》收集资料，采用“三峡库区人群健康监测信息管理系统”专用软件对数据进行分析处理。结果：2004年各监测点报告甲乙类法定传染病12种共2260例，报告发病率为579，09／10万；无死亡病例；报告丙类法定传染病5种877例，报告发病率为224．72／10万。发病居前5位的甲乙类传染病依次为病毒性肝炎、肺结核、痢疾、淋病和梅毒。以病媒生物传播为主要传播途径的虫媒和自然疫源性疾病仅有乙型脑炎发生，发病率为0．77／10万。结论：三峡库区2004年传染病发病为5年来最高水平，与国家实行网络直报有关。由于蓄水前的库底卫生清理工作进行了大面积的消毒、灭鼠工作，随着工程施工、移民新址建设和移民搬迁，与环境变化关系较为密切的虫媒和自然疫源性疾病未发生明显变化。

AN EPIDEMIOLOGY ANALYSIS OF THE MORBIDITY OF INFECTIOUS DISEASES SURVEYED BY THE PROJECT OF THREE GORGES POPULATION HEALTH SURVEY IN CHONGQING IN 2004

Objective:To analyze the morbidity of infectious diseases surveyed by the Project of Three gorges Population Health Survey in Chongqing in 2004.Methods:Data were collected according to the Project of Three Gorges Population Health Survey and were analyzed by the application of Three gorges Population Health Survey System.Results:There were 2260 of 12 infectious diseases of A and B reported,the morbidity was 579.09 per 100 000,no dead case.There were 877 cases of 5 infectious diseases of C reported,the morbidity was 224.72 per 100 000.The top five infectious diseases were virosis hepatitis,tuberculosis,diarrhea,gonorrhea and syphilis.There was only encephalitis B which was reported as the zoonosis-borne diseases and its morbidity was 0.77 per 100 000.Conclusion:Due to the direct-report by the network,the infectious disease morbidity in 2004 was the highest one during the last five years in the Three Gorges Reserviors areas.A sanitary clean had been made in the large reservoir areas including sterilization and killing rats before sluicing,and obvious Changes of morbidity on zoonosis-borne diseases had not been found during the construction of the three Gorges Project and immigrant's habitation.
