了解淮安市高校学生肺结核密切接触者筛查情况,为高校结核病防控工作提供依据.方法 对2013-2015年淮安市高校学生肺结核密切接触者进行肺结核可疑症状调查、结核菌素(PPD)试验、X线胸片和结核分枝杆菌检查.结果 2013-2015年淮安市登记高校学生肺结核密切接触者682例,密切接触者肺结核可疑症状筛查率为100%,PPD筛查率为97.21% (663/682),X线胸片筛查率为70.23% (479/682);涂阳肺结核密切接触者PPD强阳性率及X线胸片异常率(30.1%,3.5%)均高于涂阴肺结核密切接触者(16.6%,0.6%)(x2值分别为14.570,4.087,P值均<0.05);筛查发现的6例涂阴肺结核患者均由定点医院收治,但其他符合预防性服药条件的密切接触者无人接受预防性治疗.结论 学校出现结核病疫情时,应及时规范开展密切接触者筛查工作,减少疫情的播散,同时应有效落实预防性服药,减少感染者发病风险.
Abstract:
Objective To analyze the screening results of close contacts of pulmonary tuberculosis (TB) among college students in Huai'an,so as to provide evidence for TB control and prevention in schools.Methods Close contacts of TB among college students in Huai'an from 2013 to 2015 were screened by investigation of TB suspicious symptoms,PPD-test,chest X-ray,and Mycobacterium tuberculosis examination.Results Totally 682 cases of close contact of TB were registered among college students in Huaian from 2013 to 2015,100% close contacts received suspicious symptom of TB investigation,97.21% received PPD-test,and 70.23% received chest X-ray examination.The results of statistics showed that the rates of intensively positive of PPD(30.1%) and abnormal chest X-ray (3.5%)were both higher than that of closely-contacted sputum smear positive TB patients (16.6%,0.6%) (x2=14.570,4.087,P<0.05).The six sputum smear negative TB patients were screened to be treated by designed hospital,but among the other contacts that should be preventively cured,no one received preventive medication.Conclusion In order to control the epidemic of TB in school,standard screening should be carried out timely on the TB close contacts to reduce the spread of the epidemic,and simultaneously,preventive medication should be carried out on the contacts to reduce the risk of morbidity.
