目的对中小学生卡介菌纯蛋白衍生物(purified protein derivative of bacillus calmette guerin,BCG-PPD)的试验结果进行分析,为制订有效的防控措施提供依据。方法 2007年1月选择溧水县柘塘镇2所小学、1所中学的在校学生380名,进行BCG-PPD试验,观察试验结果。结果 380名中小学生BCG-PPD试验总阳性率为41.84%,男生45.60%,女生37.97%,比较差异无统计学意义(χ2=2.02,P>0.05);小学生57.04%,初中生33.46%,比较差异有统计学意义(χ2=19.87,P<0.05)。结论对中小学生进行BCG-PPD试验,了解结核杆菌在学生中的感染情况,筛查疑似感染者,做到早发现、早诊断、早隔离、早治疗,可以有效降低校园中结核病的发病率。
Objective To analyze the test results of purified protein derivative of bacillus calmette guerin (BCG-PPD) in primary and secondary school so as to provide evidence for effective prevention and control measures. Methods In January 2007, 380 elementary school students from two primary schools in Qiantang Town, Lishui County were selected for BCG-PPD test and the test results were observed. Results The positive rates of BCG-PPD in primary and secondary school students were 41.84%, 45.60% for boys and 37.97% for girls, with no significant difference (χ2 = 2.02, P> 0.05); Primary school students 57.04% and junior high school students 33.46% The difference was statistically significant (χ2 = 19.87, P <0.05). Conclusions BCG-PPD test for primary and secondary students to understand the infection of Mycobacterium tuberculosis in students screening of suspected infection, so early detection, early diagnosis, early isolation, early treatment, can effectively reduce the incidence of tuberculosis in the campus.
