| 摘 要： | 目的 了解甘肃省2006-2011年肾综合征出血热(hemorrhagic fever with renal syndrome,HFRS)的发病趋势及鼠类种群密度和带病毒情况。 方法 人间疫情资料来源于中国疾病监测信息系统,捕鼠采用夹夜法,鼠带病毒检测采用免疫荧光法,鼠血清抗体检测采用酶联免疫吸附试验(ELISA)法。 结果 2006-2011年全省HFRS报告发病数分别为35、10、25、13、6和5例,呈散在分布于9个市(州),主要集中在甘南州30例、平凉市25例、天水市15例;人群分布以男性青壮年农牧民为主。6年间捕获鼠类10种1090只,平均捕获率为8.95%,2006年最高为17.32%,此后逐年下降,2011年为4.45%;野外以黑线姬鼠为优势种,占47.64%,室内以褐家鼠为优势种,占65.12%。鼠平均带病毒率为1.01%(11/1090),带病毒鼠种黑线姬鼠10只,社鼠1只。 结论 甘肃省HFRS疫情维持在很低的水平,黑线姬鼠是主要的传染源及宿主,疫区仍为姬鼠型为主的混合型疫区。加强鼠间疫情的监测对出血热防控具有重要的指导意义。

Surveillance of hemorrhagic fever with renal syndrome in Gansu, 2006-2011 |

| Abstract: | Objective To understand the incidence trend of hemorrhagic fever with renal syndrome (HFRS) and the density and hantaan virus carriage of rats in Gansu province from 2006 to 2011. Methods The human HFRS incidence data were collected from national disease surveillance information system. Rats were captured by using traps. Rat’s Hantaan virus carriage was detected by using immunofluorescence assay and rat’s serum hantan virus antibodies were detected by using ELISA. Results From 2006 to 2011, the annual case number of HFRS was 35, 10, 25, 13, 6 and 5 respectively. The cases were distributed sporadically in 9 municipalities (prefecture), but mainly in Ganan (30), Pingliang (25) and Tianshui (15). The cases were mainly young male farmers or herdsmen. Totally 1090 rats (10 species) were captured. The captured rat number was highest in 2006. Apodemus agrarius was the predominated species in open country (47.64%), while Rattus norvegicus was the indoor predominated species (65.12%). The rat virus carriage rate was 1.01% (11/1090). Ten rats carrying virus were mainly Apodemus agrarius (10/11). Conclusion The incidence of HFRS was low in Gansu. Apodemus agrarius is the major infection source and host in the mixed type foci. It is important to strengthen the surveillance of the epidemic in rats to prevent and control HFRS. |
