摘要
目的了解2006～2013年丹东市肾综合征出血热（HFRS）的流行病学特征和鼠间监测情况，为制定针对性措施提供科学依据。方法用描述流行病学方法分析丹东市HFRS的疫情资料，鼠间监测采用夹夜法，对捕到的鼠鉴别鼠种后取肺组织，进行HFRS病毒抗原检测，计算鼠密度和鼠带毒率。结果2006—2013年丹东市累计报告HFRS721例，发病率在2．24／10万～5．93／10万之间，年平均发病率为3．86／10万；凤城和宽甸两地发病最高，占发病总数的77．12％（556／721），各地间发病率差异有统计学意义（X2=38．94，P〈0．01）；HFRS发病高峰月基本集中在1月、10月、11月、12月；HFRS发病人群主要为农民；男女性别比例为2．79：1，性别间差异有统计学意义（x。=18．27，P〈0．01）；鼠间监测居民区春季平均鼠密度为6．00％，平均鼠带毒率为22．87％，秋季平均鼠密度为5．86％，平均鼠带毒率为20．58％；野外春季平均鼠密度为6．86％，平均鼠带毒率为16．66％，秋季平均鼠密度为5．90％，平均鼠带毒率为19．20％。结论丹东市HFRS疫情主要受风城和宽甸两个县级城市影响，符合野鼠型的流行病学特点，发病人群以青壮年农民为主，丹东市的鼠密度和鼠带毒率处于较高水平，存在小范围野鼠型人间HFRS疫情暴发的可能性。丹东市应采取加强鼠监测和秋季灭鼠，同时加强对重点人群健康教育等措施为主的综合性防控措施。
Objective To analyze the results of surveillance of hemorrhagic fever with renal syndrome （HFRS） in Dandong city and to provide scientific bases for formulating specific measures. Methods The results of surveillance of HFRS in Dandong city were analyzed by descriptive epidemiology method . The vector rats were caught and the HFRS virus antigen in the lung tissue of rats were detected and the rat density and infection rate calculated. Results Totally 721 HFRS cases were reported in Dandong city with the incidence rates of between 2.24/10-5.93/10 per million. The average annual incidence rate was 3.86/10 per million; The incidence rates was the highest （77.12%,556/721）,showing significant difference in incidence in different areas（χ2=38.94,P〈0.01）;The incidence peak of HFRS was mainly in January, October, November, December and most the cases were farmers and the male to female ratio of 2.79：1,revealed significant differences（χ2=18.27,P〈0.01）; The average rat density in residential areas in Spring and Autumn were 6% and 5.86% with virus carrying rate of 22.87% and 20.58%.While the average rat density in the Spring and Autumn in the field were 6.86% and 5.90% with the virus carrying rates of 16.66% and 19.20% rats with poison in the autumn. Conclusion HFRS epidemic situation in Dandong is mainly affected by Fengcheng and Kuandian in accordance with the epidemiological characteristics of wild type HFRS, young farmers were the main group infected. The rat density and virus carrying rate were higher in Dandong city and there is the potential of occurrence of small scale infection of HFRS epidemic among humans. Therefore integrated measures including active monitoring and health education be carried out.
