淄博市农村流行性出血热鼠间带毒状况调查

目的了解淄博市农村鼠密度、鼠间带毒率以及流行性出血热的流行情况，以制定有效综合防制措施提供科学依据。方法选择流行性出血热发病率较高的淄川区、沂源县和博山区为调查点。各调查点同时用标准鼠夹，晚放晨收，记录有效鼠夹数、捕获鼠数并分类。采集样本应用间接免疫荧光法（IFAT）检测抗原。结果2004-2007年三区县调查点平均鼠密度为2．81％，其中室内、外鼠密度分别为2，38％和3．27％，褐家鼠、小家鼠为优势种群；平均鼠间带毒率为8．05％。结论淄博市流行性出血热鼠间带毒率较高，应进一步加强有效综合防制措施，降低鼠密度．灭鼠重点放在经济发展相对落后的农村。

Survey of virus-carrying status of rats in rural areas prevalent with epidemic hemarrhagic fever in Zibo City.

Objective To survey the virus - carrying rate and population density of rats in rural areas prevalent with epidemic hemarrhagic fever and provide scientific reference for control the disease. Methods Three Districts of Ziehuan, Yiyuan and Booshan highly prevalent with hemarrhagic fever were selected as surveying sites and rats were captured and antigen was detected by using IFAT. Results In the year of 2004-2007 the average density of rats in the three districts was 2. 81%, of which the indoor and outdoor density were 2.38% and 3.27%, respectively. The average of virus - carrying rate of rats was 8.05%. The Rrattus norvegicus and Mus musculus were the dominant species. Conclusion The virus - carrying rate of rats in Zibo is higher higher than that of the average national level （2.75%）, Thus effective and integrated control measures be taken to reduce rat density and control the prevalent of epidemic hemarrhagic fever in this area.
