黑河市肾综合征出血热自然疫源地性质调查研究

Investigation and Study on Natural Epidemic areas of HFRS(Hemorrhage Fever with Renal Syndrome)in Heihe

１９９８年８月在我国肾综合征出血热老疫区黑龙江省的黑河市所辖的爱辉区（罕达气、锦河农场）、逊克县（干岔子乡）、嫩江县（山河农场）和孙吴县（北孙吴村）的林区和田野进行疫源地性质调查。通过现场调查和血清学检测，查明了汉坦病毒宿主动物结果的优势种为黑线姬鼠，占夹捕动物种类构成的５１０２％（４２６／８３５）；捕获动物总密度高达１８５７％（８３５／４４９６），其中黑线姬鼠密度９４８％（４２６／４４９６）；捕获动物的汉坦病毒总感染率为５３８％（５１／９４８），其中小兽感染率为５０２％（４５／８９７），鸟类感染率为１１７６％（６／５１），抗汉坦病毒抗体阳性鸟类有５种：即东北云雀、北日雀、眉白长爪脊鸟令鸟、柳莺和野驹；黑线姬鼠感染率为８５４％（４１／４８０），占感染动物总数的８０３９％（４１／５１）。结论：黑河市境域，半个多世纪以来，流行性出血热自然疫源地的性质，基本上没有改变，依然是姬鼠肾综合征出血热自然疫源地。

Investigation of the natural epidemic area of HFRS and been done in Aug(6/51) were birds;the birds that HFRS antibody were positive included Galerida cristata leautungensis,Parus ater amurensis,Motaccilla flava simillima,Acanthopneuste nitidus plumbeitarsus and ust 1998 in the field and forest region of Aihui District(Hand Daqi and Jingf Apodemus ahe Farm),Xunke County(Gan Chazi Country),Nenjang County(Shanhe Farm)and Sunwu County (the Northern Sunwu Village),which were the old epidemic areas of HFRS and belonged to Heihe district of Hei Longjiang Province.Through the investigation and serum examination,it was clear that the dominant host animals of Hantavirus were Apodemus agrarius that occupied 51 02%(426/835) of the captured animals;the total density of the captured animals was 18 57%(835/4496),among them 9 48%(426/4496) were Apodemus agrarius.The infective rate of HFRS in the catured animals was 5 38%(51/948),in which 5 02%(45/897) were small animals and 11 76%(6/51) were birds;the birds that HFRS antibody were positive included Galerida cristata leautungensis,Parus ater amurensis,Motaccilla flava simillima,Acanthopneuste nitidus Plumbeitarsus and Luscinia calliope callipe;the infective rato of Apodemus agrarius was 8 54%(41/480) that occupied 80 39%(41/51) of all infected animals.This investigation shows that there is almost no change about the natural epidemic areas of HFRS in Heihe district over the past half century and the predominant host animals are Apodemus agrarius.
