【摘要】：目的了解温岭市某职业高中学生肺结核发病情况,为预防结核病在学生群体中的传播蔓延提供参考依据。方法通过对发病学生的流行病学调查,接触者进行PPD试验、胸部X线检查及跟踪随访。结果疫情班级活动性肺结核13例,罹患率为28.89%(13/45);PPD试验,疫情班级强阳性12例,阳性16例,阳性、强阳性率为65.12%(28/43),对照班级阳性2例,无强阳性,阳性、强阳性率为7.14%(2/28),疫情班级高于对照班级,差异有统计学意义(χ2=24.11,P0.01);疫情班级PPD试验结果,11例活动性肺结核中阴性2例,PPD阴性率为18.18%(2/11),疫情班级PPD试验结果与活动性肺结核差异无统计学意义(χ2=3.38,P0.05);首发病例为涂阴肺结核患者;首发病例隐瞒病情、中断治疗,导致疫情在聚集性场所扩散蔓延。结论早期及时发现病人、积极规范抗结核治疗是预防肺结核传播的关键;PPD试验作为活动性肺结核筛查存在局限性,需结合胸部X线检查。
