          Objective To understand epidemiology and associated factors of delay for tuberculosis in schools of Jiaxing, and to provide basis for the strategy of pulmonary tuberculosis prevention and control in schools.

          Methods Based on the Tuberculosis Management Information System, the information of school tuberculosis cases in Jiaxing from 2011 to 2020 was collected, and the epidemiological characteristics were analyzed by descriptive epidemiology.

          Results A total of 436 student pulmonary tuberculosis patients and 46 teacher pulmonary tuberculosis patients were reported in Jiaxing from 2011 to 2020. The average annual incidence rate in teachers(10.70/100 000) was higher than that in students (6.16/100 000) (χ 2 = 13.06, P<0.05). The incidence rate of school pulmonary tuberculosis (6.59/100 000) was lower than that in the whole population (37.91/100 000) (χ 2 = 184.63, P<0.05). The school pulmonary tuberculosis patients mainly occurred from March to May, accounted for 11.62%, 11.00%, 9.96% respectively. The incidence rate of school pulmonary tuberculosis patients in county level was lower than in urban district in 2012, and higher than in urban district in 2017 and 2020 (χ 2 = 4.61, 5.72, 4.02, P<0.05). Most student pulmonary tuberculosis patients aged from 15 to 19 years old, the percentage was higher in males (90) than in females (75) in students. The reported incidence rate of pulmonary tuberculosis in primary school and junior high school teachers was higher than that in the same students (χ 2 = 24.34, 14.87, P<0.05). Passive case-finding including clinical symptomatic inspection and referrals was the main way to find cases. The detection delay rate was 34.23%.

          Conclusion Early detection, prompt and scientific treatment, shortening the delay time were key to prevent the spread of the school tuberculosis. It is of great significance to reduce the occurrence of clustering in outbreak and public health emergency.


          【摘要】 目的 分析嘉兴市学校肺结核流行趋势及特征, 为推动学校结核病防控工作提供依据。 方法 从“结核病信息 管理系统”中导出 2011—2020 年嘉兴市学校肺结核病案信息, 利用描述流行病学方法对监测数据进行分析。 结果 2011—2020 年嘉兴市累计报告学生和教师肺结核病例分别为 436 和 46 例, 教师肺结核年均报告发病率(10.70/10万)高 于学生 (6.16/10万) (χ 2 = 13.06, P<0.05); 学校肺结核年均报告发病率(6.59/10 万)低于全人群报告发病率(37.91/10 万) (χ 2 = 184.63, P<0.05); 学校肺结核以3—5月发病居多, 分别占比 11.62%, 11.00%, 9.96%; 2012 年县级学校肺结核发病率 较市级低, 2017 和 2020 年较市本级高 (χ 2值分别为 4.61, 5.72, 4.02, P 值均<0.05); 15~19 岁学生肺结核病例最多, 男生肺 结核病例数(90 名)占比高于女生(75 名); 小学教师和初中教师比同学段院校学生肺结核报告发病率高 (χ 2 值分别为 24.34, 14.87, P 值均<0.05); 发现方式以因症就诊、转诊等被动发现为主, 就诊延迟率为 34.23%。 结论 早期发现传染源、及时的科学处置、缩短就诊延迟时间是防止疫情传播扩散的关键, 对减少聚集性疫情和突发公共卫生事件的发生意义 重大。
