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 investigate the epidemic situation of hemorrhagic fever with renal syndrome (HFRS) and host animal species and virus infection in Hunan Province and provide a scientific basis for the prevention of HFRS. Methods According to the “Hunan HFRS Monitoring Implementation Plan” in 2008, epidemiological and etiological monitoring of HFRS was carried out in 4 monitoring sites across the province. Direct immunofluorescence was used to detect Hantavirus antigen in the lungs of host animals. Results A total of 487 cases were reported in 2008, with a incidence of 0.77 / 100 000, a decrease of 30.63% from 2007. A total of 397 host animals were captured at 4 routine monitoring sites with a total rat density of 2.66% and a halotavirus infection rate of 4.68%. Ningxiang County, Shaodong County, Shuangfeng County, Yanling County rat lung infection rates were 4.12%, 2.74%, 6.12%, 5.13%. Conclusion The epidemic situation of HFRS in Hunan Province is somewhat lower than that in 2007, and the infection rate of Hantavirus in host animals is high, so HFRS should be comprehensively controlled.
