ABSTRACT
Objective@#To understand the current situation of school tuberculosis prevention and control system and the implementation of daily prevention and control measures, and to provide a reference for strengthening the prevention and control of tuberculosis in schools.@*Methods@#A random sampling method was used to select schools where on site questionnaire survey was carried out, including 156 junior high schools, 78 senior high schools and 6 universities. SPSS 25.0 was used for descriptive analysis and chi square test.@*Results@#The average annual screening rates of junior high school, senior high school and university from 2015 to 2020 were 58.84%, 71.71% and 84.41% respectively, and the difference was statistically significant ( χ 2=61 247.39， P <0.01). The average annual TB detection rates were 8.69/10 5, 50.89/10 5 and 36.51/10 5 respectively, and the difference was statistically significant ( χ 2=101.20， P <0.01). The screening rate of TB screening in 2015-2020 years increased by year( χ 2 trend =70 052.10, 86 182.82 , 22 213.56， P <0.01). The detection rate of TB among junior high schools and high schools has been increasing year by year( χ 2 trend =9.27, 12.23, P <0.01). From 2015 to 2020, the proportion of tuberculosis screening, contact history, PPD and chest screening increased by year in junior high school and senior high school freshmen, and the difference was statistically significant ( χ 2=129.10, 118.10, 206.92, 37.67; 108.79, 84.90, 139.84, 51.82, P <0.01). The proportion of chest X ray screening in universities increased by year( χ 2 trend =18.33， P <0.01). In 2019, poor performance on TB control in universities mainly included, including the school responsibility system for tuberculosis prevention and control, the school s annual TB work plan and absenteeism registration and etiology tracing, the proportion was 50.00 %, 0 and 16.67% respectively, compared with junior high school and senior high school, the difference was statistically significant( P <0.05). The prevalence rates of junior high school, senior high school and university students were 33.75/10 5, 90.10/10 5 and 54.20/10 5 respectively in 2019, and the difference was statistically significant ( χ 2=104.36， P <0.01).@*Conclusion@#The proportion of TB screening for freshmen in Chongqing increased significantly during 2015- 2020. High school students are still the focus of school based tuberculosis prevention and control. Improving the proportion of tuberculosis screening，strengthening and standardizing physical examination and screening，and establishing a clear responsibility system for prevention and control are effective means to prevent and control the spread of tuberculosis on campus.
