The Serveillance 05 Disease of Natural Focus and Analysis of Its Epidemic Factors at Maoming Port Area

目的通过调查茂名口岸地区鼠形动物中鼠疫、斑疹伤寒、流行性出血热等自然疫源性疾病感染情况,评估该地区自然疫源性疾病流行风险及因素,为口岸传染病防治工作提供指导。方法采用一般的病媒生物调查方法和血清学检测方法。结果在220份血清样本中,发现斑疹伤寒阳性22份,感染率10.00%;恙虫病阳性16份,感染率7.27%;流行性出血热阳性7份,感染率3.18%;钩端螺旋体阳性1份,感染率0.45%。鼠形动物总染蚤、革螨、恙螨、硬蜱指数分别为0.2、3.5、36.3、0.1,染蚤、革螨、恙螨、硬蜱率分别为8.8%、39.2%、31.1%、4.0%。结论茂名口岸地区存在恙虫病和流行性出血热流行因素,有流行风险。

Objective To estimate the epidemic risk and affect factors of Disease of natural focus by investigation of the infection condition of plague、typhus and epidemic hemorrhagic fever(EHF)et al in mouse at Maoming port area,and provide scientific basis for the prevention and control of Disease of natural focus at port area. Methods The common method of vector biological survey and the serological exam method were used. Results Serological exams show that 22 cases of endemic typhus with 10.00% infection rate,16 cases of scrub typhus with 7.27% infection rate,7 cases of epidemic hemorrhagic fever with 3.18% infection rate and 1 case of leptospirosis disease with 0.45% infection rate have been found In 220 blood serum samples,The total infection index of mouse infected with flea,Gamasid mite,chigger and ixodid is separately 0.2,3.5, 36.3 and 0.1,the total infection rate of mouse with flea,Gamasid mite,chigger and ixodid is respectively 8.8%,39.2%,31.1% and 4.0%. Conclusion The epidemic factors and epidemic risk of typhus and epidemic hemorrhagic fever exists in Maoming port area.
