【摘要】：目的对一起在高校学生中发生的肺结核疫情进行调查分析。方法对患病学生的140名密切接触者进行了流行病学调查、结核菌素试验、胸片X-线检查和痰结核菌等病原学检查。结果在首发病例班级及同寝室学生中又筛查出3例肺结核患者,使得此次疫情发病人数达到了6人,致使该班罹患率达到17.1%(6/35);在140名密切接触者中进行结核菌素试验,单纯PPD强阳性者(硬结平均直径≥15 mm,或有水泡、溃破)为78人,强阳性率达到55.7%(78/140)。结论本次高校学生中发生的肺结核疫情是由于综合性医院对首发患病学生未能及时明确诊断和有效隔离,导致传染源长期暴露在聚集性人群中,以及学生寝室通风不良和课业繁重休息不好等综合因素所引起的。
