河北省2001～2005年肾综合征出血热监测分析

ANALYSIS OF HFRS SURVEILLANCE IN HEBEI PROVINCE FROM 2001 TO 2005

[目的]分析河北省近5年肾综合征出血热(HFRS)的流行特征,为制定有效的防制措施提供科学依据。[方法]收集全省近年HFRS的人群发病情况、疫源地及人群隐性感染情况,并对其流行强度进行分析。[结果]近年来,河北省HFRS发病一直维持在较高水平,2002年以后呈下降趋势,高发地区由中南部向东部地区转移。发病呈现春峰型,发病率高,病死率低,符合家鼠型(Ⅱ型)流行特征。[结论]河北省目前HFRS预防控制的重点应在东部的秦皇岛市和唐山市,防控措施仍应坚持“监测和宣传并举,灭鼠与免疫并重”的原则。

[Objective] To study the epidemic characteristics of HFRS in Hebei province from 2001 to 2005, and provide scientific guidance for making effective prevention and control strategy. [ Methods] The data of incidence status, the infection status of epidemic focus and inapparent infection were collected, and the epidemic intensity of HFRS in recent years was analyzed. [ Results] In recent years, the incidence of HFRS in Hebei province was keeping on a high level. There was a descending tendency after 2002. The areas of high incidence transfered from the Middle South to the East. It presented a characteristic of spring peak, high incidence, low fatality rate, which accorded with the epidemic characteristics of Rattus type. [ Conclusions] The focal points of prevention and control are in Qinhuangdao and Tangshan in the eastern part of Hebei province at present. We should still hold on the principle of ＂Develop simultaneously on surveillance and propaganda, pay equal attention to deratization and immunization＂ .
