2007年河北省肾综合征出血热流行特征分析

Epidemic characteristics of hemorrhagic fever with renal syndrome in Hebei province in 2007

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 provide scientific evidence for the prevention and control of hemon＇hagic fever with renal syndrome （HFRS） by investigating and analyzing its epidemic characteristics in 2007. Methods The prevalent situation of HFRS was summarized and analyzed, and host animals were monitored. Results A total of 372 HFRS cases were reported, 2 in deaths. The incidence rate was 0.54/100 000 and the mortality rate was 0.54%. All the cases were distributed in 101 counties （cities, distriets）, whieh mainly focused in Qinhuangdao and Tangshan. The peak was in spring and summer. The susceptible population was mainly the young and middle-aged, and the ratio of male to female was 2.84： 1. The incidence rate of peasants amounted for 69.09%. The rat density in the residential area was 2.21%, and the rate of carrying hanta virus was 1.77%. And the density in the field was 1.17%, and the rate of earuing hanta virus was 1.42%. Raltus norvegicus was the dominant species. Conclusion The incidence of HFRS aeeorded with the epidemic eharacteristics of Rattus type, and the control emphasis was put in the Qinhuangdao and Tangshan. Accordingly, it shouht take the integrated management measure in key areas to control the prevalence of HFRS.
