Epidemiological survey of incidence of Salmonella infection in workers in Guigang City

目的掌握广西贵港市从业人员沙门菌携带状况,为制订本市肠道传染病防治规划提供依据。方法对2006～2008年在本中心进行健康体检人员的肛拭标本,按照GB/T4789-2003标准检测沙门菌,针对带菌者的流行病学特点进行分析。结果检测标本37597份,检出沙门菌阳性标本83份,检出率为0.22%;各年检出率分别为0.16%、0.35%、0.15%;36个月中有25个月检出沙门菌,占69.44%;每年2、3季度带菌率最高;带菌率随年龄增长升高;男女带菌率差别有统计学意义,χ2=7.38,P<0.005;3年检出的服务点有71个,其中仅有1人带菌的服务点有62个,占87.32%。结论贵港市从业人员沙门菌携带者的流行病学特点,在时间、年龄、性别、服务点的分布上都非常分散、隐蔽,并能正常工作,当食品、饮用水受其粪便污染时,可发生群体性食物中毒;提示沙门菌监测工作是一项极为严峻、艰巨而又十分重要的工作。
