目的了解双峰县近3年钩体病的疫情动态变化,为进一步做好钩体病的预防与控制提供依据。方法2005-2007年按照《湖南钩端螺旋体病监测实施方案》进行钩体病的监测,收集钩体病疫情资料,开展钩体的宿主动物带菌率与带菌种群调查,以及开展对健康人群与病例的血清学监测。结果双峰县钩体病疫情在2007年突然升高,波及范围广,且鼠密度、宿主动物的带菌率也突然升高,病例血清学分型和宿主动物菌群均为黄疸出血群。健康人群血清抗体阳性率在60%左右。结论双峰县钩体疫情的升高与鼠密度、宿主动物带菌率可能存在关联,但需要进一步长时间的监测观察,同时应提前监测,加强监测数据分析,及时预警疫情。在疫情低发的情况下,仍应采取灭鼠和提高免疫力的预防措施。
Objective To understand the dynamic changes of leptospirosis in Shuangfeng County in recent 3 years and provide basis for further prevention and control of leptospirosis. Methods From 2005 to 2007, surveillance of leptospirosis was conducted in accordance with the “Implementation Plan of Hunan Leptospirosis Surveillance,” collection of leptospirosis epidemic situation data, carrying out host organism infection rate and carrying population investigation of leptospira, and carrying out investigation on healthy population and cases Serological surveillance. Results The incidence of leptospirosis in Shuangfeng County suddenly increased in 2007 and spread to a wide range. However, the rat density and the carrier rate of host animals also increased suddenly. Serological typing and host animal flora of both cases were all jaundice bleeding. Serum antibody positive rate of healthy people is about 60%. Conclusions The increase of leptospirosis in Shuangfeng County may be related to the density of mice and the carrier rate of host animals. However, further monitoring is needed in the long term. Monitoring should be done ahead of time to strengthen monitoring data analysis and alert the epidemic in time. In the case of low outbreaks, precautionary measures should be taken to eradicate and improve immunity.
