2000—2013年云南省罗平县鼠疫监测分析

Monitoring analysis of plague in Luoping county, Yunnan province, from 2000 to 2013

目的分析曲靖市罗平县2000—2013年鼠疫监测结果。方法采用资料分析法,整理罗平县近2000—2013年的鼠疫监测数据,计算鼠密度、蚤指数、染蚤率等监测指标。计数资料采用χ^2检验,P〈0.05为差异有统计学意义。结果 2000—2013年,罗平县检验鼠7 044只,分离鼠疫菌6株,鼠疫菌检出率为0.085%;检验媒介3 654只,未分离到鼠疫菌;监测鼠血清2 241份,阳性血清19份,阳性检出率为0.85%;反向血凝检验19份,阳性19份,阳性检出率为100%。鼠密度变化无规律性,不同年份的鼠密度比较差异有统计学意义（P〈0.05）。染蚤鼠1 113只,染蚤率为15.80%,梳检媒介3种3 654只,印鼠客蚤占42.42%;缓慢细蚤占38.62%;不等单蚤占18.97%,蚤指数为0.52,不同年份染蚤率和蚤指数比较差异均有统计学意义（均P〈0.05）。结论罗平县鼠疫处于低度活跃状态,要加强监测工作,预防鼠疫死灰复燃。

Objective To analyze the results of plague surveillance in Luoping county from 2000 to 2013. Methods The information analysis was used to analyze the data of epidemic surveillance of plague in Luoping county in 2000 to 2013. The monitoring indexes such as rat density, flea index and flea rate were calculated. Count data was processed by chi square test, P〈0.05 was considered statistically significant. Results From 2000 to 2013, a total of 7 044 rat were check, and 6 plague bacillus were separated, the detection rate was 0.085%. A total of 3 654 medium were check, no plague bacillus were separated. 2 241 copies of serum were monitored, 19 copies of positive serum, the positive rate was 0.85%. Reverse hemagglution test 19, 19 positive samples, positive rate was 100%. Rat density changes of the mice without regularity, the rat density have significant difference in different years （P〈O.05）. Dye rat flea of 1 113, the flea-carrying rate was 15.80%, and flea index was 0.52. The flea-carrying rate and flea index have significant differences in different years （all P〈0.05）. Conclusion The plague in the low active state in Luoping county, should strengthen the monitoring to prevention the plague resurgence.
