某部驻地市郊某乡是肾综合征出血热(HFRS)老疫区,属野鼠型自然疫源地。该乡自1961条确诊首例病例以来,常有病例发生,1979后明显增多。1980～1986年期间,年均发病率为0.77‰。某部1969年进驻该地后,时有病例发现,1980～1986年年均发病率为1.89‰。为了掌握本病在该部及驻地不同人群的隐性感染强度,为进行防治提供依据,于1986年12月～1987年1月(流行高峰后期)开展了本病血清流行病学初步调查。
A certain resident in the suburbs of a resident is an old epidemic area of hemorrhagic fever with renal syndrome (HFRS), which belongs to a wild-type natural foci. The township since 1961 confirmed the first case since, often cases, increased significantly after 1979. From 1980 to 1986, the average annual incidence was 0.77 ‰. A certain department stationed in the area in 1969, sometimes found cases, the average annual incidence from 1980 to 1986 was 1.89 ‰. In order to grasp the hidden infection intensity of this disease in different population in this department and resident, provide the basis for prevention and treatment, from December 1986 to January 1987 (late peak period) to carry out a preliminary serological epidemiological survey of this disease.
