目的了解安义县2007年肾综合征出血热(HFRS)的流行特点和流行趋势,为防治提供依据。方法对安义县2007年人间疫情及宿主动物监测资料进行分析。结果2007年安义县HFRS发病率为6.13/10万,5-6月和11-12月发病较多,占全年病例总数的81.25%。人群隐性感染率高,达21.00%,无死亡病例。捕获鼠类7种207只,其中居民区以褐家鼠为优势种,野外以黑线姬鼠为优势种;鼠带病毒率为1.49%,带病毒鼠均为居民区小家鼠。鼠血总抗体阳性率为12.08%。结论安义县HFRS符合家鼠型为主的混合型疫区流行特征。2007年发病率上升较快,应继续加强疫情监测,贯彻“灭鼠和免疫并重”的措施,控制HFRS的发病率。
Objective To understand the epidemiological characteristics and epidemic trend of hemorrhagic fever with renal syndrome (HFRS) in Anyi County in 2007, so as to provide basis for prevention and treatment. Methods Anixian 2007 human epidemic and host animal monitoring data analysis. Results The incidence of HFRS was 6.13 / 100,000 in Anyi County in 2007, with more incidence in May-June and November-December, accounting for 81.25% of the total number of cases in the year. The hidden infection rate of the crowd is high, up to 21.00%, no deaths. 207 species of 7 species of rodents were captured, of which Rattus norvegicus was the dominant species in residential area, and Apodemus agrarius was the dominant species in the wild. The virus rate was 1.49% in mice and the mice were all resident mice. The positive rate of rat blood total antibody was 12.08%. Conclusion The epidemic characteristics of HFRS in AnYi county are consistent with that of domestic mice. In 2007, the incidence rate rose rapidly. The epidemic situation should be continuously monitored and the “rodent control and immunization” should be implemented to control the incidence of HFRS.
