目的通过对2007年河北省肾综合征出血热(HFRS)流行特征及监测数据进行分析,为控制该病的流行提供科学依据。方法总结分析全省HFRS流行概况,对宿主动物进行监测。结果2007年河北省共报告HFRS病例372例,死亡2例,发病率0.54/10万,病死率为0.54%。病例分布于全省101个县(市、区),主要集中于秦皇岛和唐山市。季节特征呈春峰型,以青壮年为主,男女发病之比为2.84∶1;农民发病占69.09%。居民区鼠密度为2.21%,带病毒率为1.77%;野外鼠密度为1.17%,带病毒率为1.42%。居民区和野外的优势鼠种均为褐家鼠。结论河北省HFRS发病符合家鼠型流行特征,重点防病区域为东部的秦皇岛和唐山市。为此,采取针对家鼠型为主的加强重点区域的综合防治措施,以控制HFRS的流行。
Objective To analyze the epidemiological characteristics and monitoring data of hemorrhagic fever with renal syndrome (HFRS) in Hebei Province in 2007, and provide a scientific basis for controlling the epidemic of this disease. Methods The epidemic situation of HFRS in the whole province was analyzed and analyzed, and the host animals were monitored. Results A total of 372 HFRS cases were reported in Hebei Province in 2007, with 2 deaths, the incidence rate was 0.54 / 100000 and the case fatality rate was 0.54%. The cases were distributed in 101 counties (cities and districts) in the province, mainly in Qinhuangdao and Tangshan. The seasonal characteristics of spring peak type, mainly young and middle-aged, male and female incidence ratio of 2.84:1; 69.09% incidence of peasants. The residential area had a density of 2.21%, with a virus rate of 1.77%. The wild rat density was 1.17% with a virus rate of 1.42%. Dominant species in residential areas and in the wild are Rattus norvegicus. Conclusion The incidence of HFRS in Hebei Province is in line with the epidemic characteristics of domestic mice. The key disease prevention areas are Qinhuangdao and Tangshan in the east. To this end, we adopt a comprehensive prevention and control measures to strengthen the key areas of home-based mice to control the prevalence of HFRS.
