摘要
目的 了解四川省肾综合征出血热 (HFRS)流行规律和特征、影响因素 ,为防制提供依据。方法 疫情资料来源于疫情报告系统 ,现场调查方法参照有关部门标准 ,血清学检测采用常规免疫荧光法[1] 。结果 1984-2 0 0 0年 ,四川省共报病 2 64 42例 ,死亡 910例。发病率逐年下降 ,除新疫区盐源县外 ,近几年全省控制在 1/10万左右 ,季节高峰消失 ,呈高度散发状态。健康人群隐性感染率在 1 5 %左右 ,且与年度和地区发病高低无明显联系 ,患者血清学诊断符合率为78 42 %。总鼠密度在 12 %左右 ,室外略高于室内 ,室内外主要宿主动物分别为褐家鼠、黑线姬鼠。总鼠带病率为3 0 % ,其中黑线姬鼠最高 (6 43 % )。结论 四川省是HFRS的混合型疫区 ,其人群分布和流行特征与全国情况基本一致 ,监测为防制提供了科学依据。
Objective To study the epidemic regular Patten,characteristics and influence factors of HFRS and to provide a basis for prevention and control.Menthods Study materials came from network of epidemic reporting system.Field investigation methods were referred to relevant standards.IFA was used for serologic detection.Results A total of 26442 cases were reported and 910 cases died from 1984 to 2000.The incidence rate decreased year by year and was controlled below 1/100000 except for the newly epidemic area,i.e.Yanyuan county,in recent years.The season peak disappeared and cases were highly sporadic.The inapparent infection rate in health population was 1.50% or so,which showed no dramatic relationship with year and area.The accordance rate between serologic diagnosis of patients and clinical diagnosis was 78.42%.The total density of rats was about 12.00% and it was slightly higher outside than that of inside.The main host animal were Rattus norvegicus and Apodemus agrarius.The total carrier rats of Hantan virus in the small animals accounted for 3.0%,in which the Apodemus agrarius was the highest (6.43%).Conclusion The type of epidemic areas was the mixed one in our province.The distribution of population and epidemic characteristics were accordance with the condition of the whole China.And the surveillance provided a scientific basis for prevention of HFRS.
