1982年9至11月选择江苏省不同流行强度的HFRS疫区及非疫区计11个点进行了包括疫源地地貌、鼠类种群及密度、革螨种群及指数、鼠类带毒率、健康人群隐性感染率等项内容的综合调查。结果表明：
1.黑线姬鼠是各疫区的野外优势鼠种。其密度在高发区为3.90%，在中发区为2.54%。在低发区为0.80%，而在非疫区为0.56%；其HFRS抗原检出率在高发区为4.61%，中发区为3.96%，低发区为2.01%，非疫区为0。
2.流行前期黑线姬鼠密度与带毒率的乘积，同各调查点的发病率呈明显正相关；与调查点所在县1981、1982两年总发病率的相关系数为rs=0.8334，P<0.01；与调查点所在公社1981、1982两年总发病率的相关系数为rs=0.9524，P<0.0025。认为可将此指标纳入HFRS监测内容。
3.各疫区黑线姬鼠窝巢的优势螨种均为格式血厉螨，但其指数差异不显著。
4.疫区健康人群HFRS隐形感染率很低，高发区为1.02%，中发区为1.10%，低发区为0.60%，不足以构成影响本病流行的自然免疫屏障。 |

We chose 11 localities with various degree endemicity of hemorrhagic fever with renal syndrome (HFRS) and with non-endemicity in Jiangsu Province, from September to November 1982. Many factors were studied in a comprehensive survey.
The results in brief are listed below:
1. The predominating species of rats in the endemic area was Apodemus agrarius. Its density was:3.9% in highly endemic area, 2.54% in intermediate, 0.80% in low and 0.56% in non-endemic area. The HFRS antigen carrier rates detected were 4.61%, 3.96%, 2.01% and 0 in the above-mentioned areas respectivily.
2. The relation between the product of the density of Apodemus agrarius and its virus carrier rates before the season of rise of HFRS incidence and the incidence of HFRS was positively correlated in various localities:in the prevalent counties in 1981, 1982, rs=0.8334, P<0.01, and in the communes in 1981, 1982, rs=0.9524, P<0.0025.
3. The predominating species of mites in the holes of Apodemus agrarius was Haemolaelaps glasgowi.
4. The latent infection rates of HFRS among healthy persons were low:1.02% in the highly endemic locality, 1.10% in the intermediate endemic areas and 0.60% in low endemic areas, so were not high enough to form a barrier of natural immunity to decrease the prevalence of this disease. |
