Objective To analyze the characteristics of pulmonary tuberculosis among students and teachers in Sichuan Province during 2012 to 2021,in order to provide a reference for the effective epidemic control of pulmonary tuberculosis in schools.Methods The epidemic data and population data of students and teachers with pulmonary tuberculosis from 2012 to 2021 were collected from the Tuberculosis Management Information System of Infection Diseases Reporting System and Statistical Yearbook of Sichuan Province.WPS 2019 software was used to organize data and make charts.SPSS 25.0 software was used for statistical analysis of the data.Statistical data were described by proportion or percentage(％),trend analysis was performed by Chi-square trend test,and differences between groups were compared by Chi-square test.The test level α was 0.05.Results From 2012 to 2021,a total of 31771 students pulmonary tuberculosis cases and 2 452 cases of teachers were registered in Sichuan Province.In 2021,the registration rate of tuberculosis among students in Sichuan Province was 30.80/105,it increased by 9.63/105 compared with 2012 of 21.17/105,and the difference was statistically significant(x2trend=3 893.517,P＜0.001).The registration rate of tuberculosis among teachers in Sichuan Province was 28.13/105,it decreased by 13.50/105 compared with 2012 of 41.63/105,and the difference was statistically significant(x2trend=57.087,P＜0.001).There were significant differences in the composition of pulmonary tuberculosis patients among students and teachers with different genders,nationalities,patient sources,etiological results and treatment classifications(all P＜0.001).Conclusions From 2012 to 2021,the epidemic pulmonary tuberculosis incidence in students had a rising trend,a falling-rising trend in teachers.The epidemic situation was more serious.The physical examination of tuberculosis should be further standardized.
