2016年9-12月,通过对重庆市某高校结核病聚集性疫情进行现场流行病学调查、个案调查、接触者筛查、现场环境和防治工作调查等方法收集资料.运用SPSS 16.0对收集数据进行整理分析.该校共发现33例患者,包括2起学生结核病聚集性疫情和28例散发患者.患者以涂阴肺结核为主,90.9％(30/33)患者通过筛查集中发现,肺结核检出率为0.30％,84.8％(28/33)患者无肺结核可疑症状,51.5％(17/33)患者有肺结核接触史,30.3％(10/33)患者经常去网吧.2014级、2015级和2016级学生肺结核检出率分别为0.48％(9/1868)、0.47％(16/3382)和0.19％(8/4213).2014级和2016级学生肺结核检出率相比差异有统计学意义(x2=4.78,P=0.029),但和2015级学生检出率比较差异无统计学意义(x2=0.00,P=0.965),2015级和2016级学生肺结核检出率相比差异有统计学意义(x2 =3.96,P=0.047).可见,该校结核病疫情较严重,应进一步加强高校结核病防控工作.“,”Data of tuberculosis (TB) which outbreak at a college of Chongqing during September and December of 2016,were collected through epidemiological study,case investigation,TB screening for contacts,environment and TB work survey,and were analyzed using SPSS 16.0.The total 33 pulmonary TB students including two aggregated cases and 28 sporadic cases.Most cases were smear negative,90.9％ (30/33) were found by screening and the pulmonary TB detection rate was 0.30％.Furthermore,84.8％ (28/33) cases had no suspected TB symptoms,51.5％ (17/33) cases had pulmonary TB contact history and 30.3％ (10/33) cases often went to Internet cafes.The pulmonary TB detection rates in grade 2014,2015 and 2016 were 0.48％ (9/1868),0.47％ (16/3382) and 0.19％ (8/4213),respectively.The pulmonary TB detection rates in grade 2014 and grade 2016 were significantly different (x2=4.78,P=0.029),and so did grade 2015 and grade 2016 2015 (x2=3.96,P=0.047).However,no significant difference was found between grade 2014 and 2015 (x2 =0.00,P=0.965).Overall,the TB burden is high in the college,TB prevention and control work should be further strengthened.
