摘要：

目的分析天津市某电子有限公司以流动人口为主的一起聚集性结核病疫情,探讨企事业单位流动人口结核病的防治措施。方法收集2017年1月至2018年4月天津市某电子有限公司确诊的19例结核病患者的个案调查表,密切接触者筛查报告及现场流行病学调查报告,对本次结核病疫情流行特点进行分析和总结。结果 19例临床确诊的结核病患者年龄为21~42岁,平均(29.68±7.29)岁;15例为外省来津务工人员,4例为天津户籍人员。8例分布在整机组装(LX)部门,7例分布在电子段组装(LVI)部门。疫情发生后,该公司与塘沽结核病防治所前后共组织了3次密切接触者筛查,共筛查LX和LVI部门和患者宿舍人员共计1796名,累计发现17例疑似患者,确诊10例(58.82%)。根据疫情的三间分布,认为此次疫情为典型的混合传播,即首次聚集没有及时处置,导致续发病例继续传播,引发二代病例。结论本次疫情以流动人口为主,呈现出一定的聚集性。强化各级各类医疗机构责任意识,加强结核病核心知识宣传教育,健全结核病防治机构与辖区内大型用工企业传染病疫情沟通制度,是控制企事业单位流动人口结核病疫情的关键。

Abstract:

Objective To analyze an aggregation outbreak of tuberculosis mainly in floating population in an electronics Co., Ltd. in Tianjin city, and to explore the prevention and control strategy of tuberculosis in floating population in enterprises and institutions.Methods The case investigation of 19 tuberculosis patients diagnosed in an electronics Co., Ltd in Tianjin from January 2017 to April 2018, screening report of close contacts and field epidemiological investigation report of the electronics co., LTD. were collected. The epidemic characteristics of this outbreak were summarized and analyzed.Results The age of the 19 clinically diagnosed tuberculosis cases were from 21 to 42 years old, with an average of 29.68±7.29 years. Fifteen patients were migrant workers from other provinces and 4 patients were Tianjin registration personnel. Eight cases were in complete machine assembly (LX) department and 7 cases were in electron segment assembly (LVI) department. After the outbreak, the company organized three close contacts screening with the Tanggu Tuberculosis Control Institute. A total of 1796 staff in LX and LVI departments and the dormitory were screened. Seventeen suspected patients were found and 10 cases (58.82%) were confirmed. According to the distribution of time, region and population, this outbreak of tuberculosis was considered to be caused by a typical mixed transmission, that was, the first aggregation was not treated in time, resulting in continued transmission and triggering secondary patients.Conclusion The outbreak of tuberculosis was mainly in floating population, showing a certain aggregation characteristic. Strengthening the responsibility consciousness of medical institutions at various levels, strengthening tuberculosis core knowledge education in the floating population, and improving the communication system of infectious diseases situation between Tuberculosis Prevention and Control Institutions and large-scale labor enterprises are the key to controlling the tuberculosis epidemic among floating population in enterprises and institutions.
