沧州市肾综合征出血热疫源地宿主动物监测分析

Monitoring and Analysis on the Host Animals of hemorrhagic fever with renal syndrome in Cangzhou City

目的掌握沧州市肾综合征出血热(HFRS)疫源地宿主动物的构成、分布及汉坦病毒携带状况,为HFRS的防制提供科学依据。方法采用夹夜法开展宿主动物调查,采用间接免疫荧光法检测汉坦病毒抗原。结果 1998-2009年居民区鼠密度波动在(0.52～5.19)%之间,鼠带病毒率在(0～27.91)%之间,宿主动物构成以褐家鼠为绝对优势鼠种,占83.03%,其次为小家鼠12.88%,大仓鼠和黑线姬鼠分别为3.61%和0.47%。结论褐家鼠是沧州市HFRS主要的宿主动物和传染源,采取以消灭住区褐家鼠为主的综合性防制措施,可以有效控制HFRS的流行。

Objective To know the Cangzhou City HFRS （HFRS） foci host animal composition,distribution and status of hantavirus carried for HFRS to provide the scientific basis for control. Method Carry out the investigation on folder host animals by night,Detect the Hantavirus antigen by indirect immunofluorescence of hantavirus antigens. Results Rodent density fluctuations in residential areas is from 0.52% to 5.19% in 1998-2009. The mouse with virus is between 0 to 27.91%,The host animal is constitute of Rattus norvegicus,absolute advantage is 83.03%,followed by Mus musculus 12.88 %,hamsters and Apodemus were 3.61% and 0.47%. Conclusions HFRS Cangzhou City Rattus norvegicus is the main source of infection of host animals and take to eliminate settlements,mainly Rattus norvegicus comprehensive control measures,can effectively control the prevalence of HFRS.
