某高校学生活动性肺结核患者密接者感染筛查分析及预防措施

Screening Analysis of the Undergraduates Who Closely Contacted with An Undergraduate Suffering from Tuberculosis and the Preventive Measures

目的某高校2007级某女生于2009年10月患肺结核后,对与该学生密接者130例的筛查结果进行分析,讨论控制大学生结核病流行的预防措施。方法 130例肺结核患者密接者(其中6例为最密接者)作为筛查对象,密接者行结核菌素试验(purified protein derivative,PPD)和拍胸片(chest X-ray,CR),最密接者还行CT和痰涂检验。结果 130名密接者的PPD试验结果显示强阳性33例,强阳性率为25.38%;CR检查结果显示密接者无阳性体征,最密接者的CT结果显示无异常。痰涂检验结果显示没有发现结核杆菌。结论从结核患者密接者各项筛查结果来看,该校结核病目前未构成群体环境肺结核疫情,没有造成传播。大学生是肺结核病传播的高危人群,应加强健康教育,提高身体素质,增强对结核病的抵抗力。应定期对在校学生进行体格检查,以便早期发现肺结核患者,并采取积极措施予以防控。

Objective To analyze the results of examination of the undergraduate who contacted closely with a female student suffering from tuberculosis（TB） and to discuss the preventive measures for checking the spread of TB in the university.Methods Totally 130 undergraduates contacted closely with the undergraduate suffering from TB and 6 of the 130 undergraduates contacted most closely with the undergraduate suffering from TB.The 130 undergraduates were subjected to examination by purified protein derivative（PPD） test and chest X-ray（CR）,the 6 undergraduates underwent computed tomography（CT） and sputum smear test besides PPD test and CR.Results Thirty-three（25.38%） of the 130 undergraduates who contacted closely with the student suffering from TB were positive for PPD test.No one showed any positive signs on CR.The CT results were normal,and the sputum smear test did not show any acid-fast bacillus in any of the undergraduates who contacted most closely with the undergraduate suffering TB.Conclusion No spread of TB has occurred due to the presence of a female undergraduate suffering from TB in the university.However,undergraduates may be at risk of suffering from TB,therefore it is important to take active actions to prevent TB in universities and colleges.
