目的 分析实验室检测在学校结核病疫情处置中的作用,为丰富学校结核病疫情防控手段提供依据。方法 按《学校结核病防控工作规范》,对某学校结核病患者的密切接触者和一般接触人群进行结核病筛查,采集相关标本进行实验室检测。结果 该学校共发现5例结核病患者。密切接触者和一般接触者共160人进行了筛查和实验室检测,PPD试验强阳性15人,强阳率9.38%。5例确诊的患者中,有4例为病原学阳性,1例涂阳,3例培养阳性,4例患者阳性标本分子生物学阳性。结论 学校是结核病疫情高发场所,实验室病原学检测在发现传染源中发挥着重要作用,应重视新诊断技术在检测过程中的应用。

Objective To analyze the role of laboratory test in the investigation and analysis of tuberculosis(TB) epidemics in schools,and to provide evidence for enriching the prevention and control measures of tuberculosis in schools. Methods According to the "Code of Practice for Prevention and Control of School Tuberculosis",TB screening was conducted for close contacts and general contacts of TB patients in a school,and relevant specimens were collected for laboratory testing. Results In this school,5 cases of tuberculosis were found.A total of 160 close contacts and general contacts were screened and tested in the laboratory.PPD test was highly positive in 15 people,with a strong positive rate of 9.38%.Of the 5 confirmed patients,4 were positive for etiology,1 was smear-positive,3 were positive for culture,and 4 were positive for molecular biology. Conclusion School is a high-risk place for tuberculosis epidemic.Laboratory pathogen detection plays an important role in the discovery of infectious sources.It is necessary to pay attention to the application of new diagnostic techniques in the detection process.
