目的对某校藏族班级结核病疫情开展调查处理,为控制疫情传播提供有效措施。方法对藏族班级师生进行胸部X线检查、PPD试验,开展流行病学调查工作,描述发病分布,查找传染源,利用SPSS16.0统计软件进行数据分析。结果 2010年12月1日至2011年5月11日,该校共发现9例肺结核病例(1例涂阳,8例涂阴),均为2010级西藏班学生,西藏班肺结核的罹患率为10.34%。其中,男性罹患率(11.94%)高于女性(5.00%)。不同PPD反应人群中肺结核发病情况有差异。结论本次疫情为一起学校结核病疫情,传染源很可能为首发病例。开展学校结核病防治健康教育是今后工作的重点,同时要注意民族差异,积极倡导健康行为,以便有效控制学校结核病疫情。
Objective To investigate and deal with the epidemic situation of Tibetan class TB in a certain school and provide effective measures for controlling the spread of the epidemic. Methods Thorax X-ray examination and PPD test were conducted on Tibetan teachers and students to carry out epidemiological investigation, to describe the distribution of the disease, to find out the source of infection, and to use SPSS16.0 statistical software to analyze the data. Results From December 1, 2010 to May 11, 2011, a total of 9 cases of tuberculosis (1 smear positive and 8 smear negative) were found in this school. All were grade 2010 Tibetans. The attack rate of tuberculosis in Tibet was 10.34%. Among them, the rate of males (11.94%) was higher than that of females (5.00%). There are differences in the incidence of tuberculosis among different PPD responders. Conclusion The epidemic situation is a school tuberculosis epidemic, the source of infection is likely to be the first case. Carrying out prevention and control of tuberculosis in schools is the focus of future work. At the same time, we should pay attention to ethnic differences and actively advocate healthy behaviors in order to effectively control the TB epidemic in schools.
