目的 调查大别山区肾综合征出血热微小疫源地演化及流行病学意义。方法 根据地理、地貌选择岳西县境内妙道山和菖蒲 2个调查点 (A点和B点 ) ,进行健康人群隐性感染调查 ,并用夹夜法调查小型兽类密度。采集捕获动物肺、血标本 ,检测汉坦病毒感染情况。结果 健康人群隐性感染率 2 .78% (2 /72 ) ;野外A点社鼠为优势鼠种 ,占夹捕小型兽类种类构成的 4 8.6 5 % (36 /74 ) ,捕获小型兽类总密度为 10 .6 2 % (74 /6 97) ,汉坦病毒 (HV)感染率为 12 .16 % (11/74 ) ,其中 10只为社鼠 ;野外B点社鼠构成比为 2 1.74 % (5 /2 3) ,小型兽类密度为 4 .31% (2 3/5 34) ,HV感染率为 8.70 % (2 /2 3) ,2只均为社鼠。结论 社鼠不仅是高山林区的主要宿主动物 ,而且是HFRS的主要传染源 ;肾综合征出血热微小疫源地已经强化。
Objective To investigate the evolution and epidemiological significance of micro-foci of hemorrhagic fever with renal syndrome in the Dabie Mountains. Methods According to the geography and geomorphology, we selected two investigation points (point A and point B) of Mt.Mounto and Acorus calamus in Yuexi county to investigate the latent infection in healthy population and investigated the density of small mammals by the method of clip-on night. Acquisition and capture animal lung, blood samples, detection of Hantavirus infection. Results The prevalence of latent infection in healthy population was 2.78% (2/72). In field, point A mice were the predominant species, occupying 48.6% (36/74) of the captured small mammals and capturing small mammals The total density was 10.62% (74/677), and the infection rate of hantavirus (HV) was 12.16% (11/74), of which 10 were social mice; 1.74% (5/2 3), the density of small mammals was 4.31% (2 3/5 34), and the HV infection rate was 8.70% (2/2 3). Conclusion The squirrel is not only the main host animal in the mountainous area, but also the main source of infection of HFRS. The micro-epidemic area of hemorrhagic fever with renal syndrome has been strengthened.
