2001—2010年广西隆林县鼠疫疫区综合处理措施效果分析

Effectiveness analysis of comprehensive measures to control the plague in the epidemic areas in Longlin county Guangxi from 2001 to 2010

目的评价2001—2010年广西隆林县鼠疫疫区综合处理措施效果。方法对原疫点进行灭鼠、指示动物调查和疫情线索搜查，采用笼捕法捕获鼠并采集鼠体蚤，计算鼠体染蚤率和蚤指数，应用病原学和血清学检测鼠体等动物的鼠疫感染状况。结果共捕鼠1008只，其中黄胸鼠占81．65％（823／1008）；获鼠体蚤571匹，印鼠客蚤占64．10％（366／571），年平均染蚤率为23．02％（177／769）、蚤指数为0．74；鼠密度由3．99％（859／21508。灭鼠前）下降到0．96％（149／15600，灭鼠后），灭鼠率为75．94％。结论持续采取综合的鼠疫疫区处理措施．可有效降低隆林县鼠疫流行的风险。

Objective To evaluating the effectiveness of comprehensive measures to control the plague in epidemic areas in Longlin county Guangxi from 2001 to 2010. Methods Original epidemic places was deratised, indicative animals were investigated, and epidemic clues were searched. Cage trapping method was used to capture rat and rat body fleas were collected in the plague epidemic areas. The flea-carrying rates and flea index of rodents were calculated based on the number of fleas collected from caged rodents. The animals were then subjected to etiological and serological tests to determine the plague infection rate. Results A total of 1008 rats were captured and 571 fleas were collected from 2001 to 2010, of which Rattus Flavipestus accounted for 81.65%（823/1008） and Xenopsylla Cheopis for 64.10%（366/571 ）. The annual average rodents infected with flea and the index of flea were 23.02%（177/769） and 0.74, respectively. The annual average density of rodents decreased from 3.99% （859/ 21 508, before deratised） to 0.96% （149/15 600, after deratised）. The deratization rate was 75.94%. Conclusion The risk of a plague epidemic in Longlin county is reduced after continued comprehensive measures be taken to deal with the disease.
