摘要
目的掌握湖南省肾综合征出血热(HFRS)疫情动态以及宿主动物种类、病毒感染等情况,为防制HFRS提供科学依据。方法按照2008年《湖南HFRS监测实施方案》,在全省4个监测点开展HFRS流行病学和病原学监测。采用直接免疫荧光法检测宿主动物肺组织汉坦病毒抗原。结果2008年共报告病例487例,发病率0.77/10万,较2007年下降30.63%。4个常规监测点共捕获397只宿主动物,总鼠密度为2.66%,鼠肺汉坦病毒感染率为4.68%。宁乡县、邵东县、双峰县、炎陵县鼠肺感染率分别为4.12%、2.74%、6.12%、5.13%。结论湖南省HFRS疫情较2007年有一定程度降低,宿主动物的汉坦病毒感染率较高,需要高度重视,综合防制HFRS。
Objective To study the epidemic source region range and type Of hemorrhagic fever with renal syndrome （HFRS）, the distribution in population and the rule of prevalence, the type of host animals and the situation of virus carrying, and to provide the scientific evidence for taking comprehensive measures to prevent and control HFRS in Hunan Province： Methods According to the Implementation Scheme of Hemorrhagic Fever with Renal Syndrome Surveillance in Hunan Prov- ince in 2008, we carried on the HFRS epidemiological and pathogenic surveillance in four surveillance spots. Direct immunofluorescence assay （DFA） was used to detect the antigen of rats＇ lungs and to investigate whether the host animals were naturally infected by Hantavirus. Results There were 487 cases reported in 2008, the annual incidence rate was 0.77/100, 000 which decreased by 30.63 % than that in 2007. Totally 397 rodents were captured in 4 surveillance spots, with the total rodent density of 2.66 %, and the Hantavirus infection rate in rodents was 4.68 %. The Hantavirus infection rates of rodents in Ningxiang County, Shaodong County, Shuangfeng County, and Yanlin County were 4.12 %, 2.74 %, 6.12 %, and 5.13 %, respectively. Conclusions The HFRS epidemic situation is decreased to a certain extent than that in 2007 in Hunan Province. The Hantavirus infection rate of the host animals is high, which suggests us to pay more attention to them and take comprehensive measures to prevent and control HFRS.
