【摘要】 目的了解清远地区流行性出血热的流行特点和趋势,为制定防控措施提供依据。方法在市辖2县设立8个监测点,采用笼日法捕鼠计算鼠密度;采用夹夜法、笼日法、挖鼠洞等多种方法在居民区和野外环境捕鼠,调查鼠类种群构成;采集鼠血清及一般人群血清,用酶联免疫吸附试验(双抗原间接法)检测血清汉坦病毒(HV)抗体;收集清远地区疫情资料,描述其流行病学特征。结果2008年全市报告病例3例,无死亡病例,年发病率为0.08/10万;采集一般人群血清237份,HV感染率为2.53%;捕获鼠形动物236只,经鉴定隶属于1目1科2属5种,优势鼠种为褐家鼠;鼠密度为10.32%;除黄毛鼠和板齿鼠外,共余3种均发现感染,总感染率为11.86%。结论清远市存在家鼠型流行性出血热疫源地,主要宿主动物为褐家鼠、黄胸鼠、黑家鼠。更多还原

【Abstract】 Objective To understand the epidemic characteristics and trends of hemorrhagic fever with ren syndrome (HFRS)in Qingyuan in 2005 . Methods Host animals were caught from 8 surveillance sites in 2 districts of Qingyuan. The host animals were classified. The epidemic data of HFRS in Qingyuan were collected and analyzed. Rat density was also surveyed and HFRS antibodies were detected with ELISA. Results There 3 patients with HFRS were reported in 2008 with an annual incidence rate of 0.08/ 100 000. Hantavirus infection rate were 2.53%. There 236 rat-like animals captured, belonged to 1 orders,1 families,2 genera and 5 species,R.norvegicus predominated,the average rat density was 10.32% . three rats were infected hantavirus with total infection rate of 11.86%. Conclusion There is natural focus for HFRS in Qingyuan and the,3 major host animals were R.norvegicus,R.flavipectus and Black norvegicus.更多还原
