博兴县灭鼠防病效果分析

Analysis of Rat-killing with EHF Morbidity Rate

进一步考查论证长期巩固灭鼠成果可有效地控制流行性出血热(EHF Epidemic hemorrhage fever)发病率。1998年再次采用了不同类型的投饵方法进行了灭鼠防病效果对照。平均鼠密度室内粉迹法1.8％,野外夹夜法0.4％,一年中出现外源性EHF病人1例,仍然保持了原有的成果。充分证明了鼠密度降低EHF发病亦明显下降的规律。

It is conformed that the achievement of long-term consolidating rat-killing can effectively control the EHF Epidemic hemorrhage qeuer morbidity rate. In 1998 we had again adapted different kinds of luring means to compare the EHF preventive effect with rat-killing. The average rat density:indoor powder-trace method 1.8% .field night rat splint method 0.4% .There is no EHF patient in the year. We have kept the achievement. It is demonstrated that the low rat density is coincident with the obvious drop of EHF morbidity rate.
