Abstract:

Objective: To understand the prevalence of latent tuberculosis infection (LTBI) and active pulmonary tuberculosis among newly admitted students in Sichuan Province in 2022, students’ tuberculosis screening results were summarized and analyzed to provide theoretical basis for implementation of newly admitted student tuberculosis screening in schools. Methods: Basic information on newly admitted students in all types of schools in Sichuan Province for the year 2022 was obtained from the provincial educational enrollment system, and a database was established using “2022 Autumn Student Enrollment Tuberculosis Screening Information Form”. Descriptive statistical analysis method was used to analyze the detection of tuberculosis and LTBI among newly admitted students, including their epidemiological characteristics and tracking result of LTBI cases taking and completing preventive treatment. Results: In 2022, a total of 2787900 newly admitted students in schools across Sichuan Province underwent standardized tuberculosis screening, accounting for 97.69% (2787900/2853817) of all newly admitted students. Active pulmonary tuberculosis was detected in 247 students, with a detection rate of 8.86/100000 (247/2787900). The prevalence among female was 10.11/100000 (145/1434131), higher than that among males which stood at 7.18/100000 (102/1419686),the difference was statistically significant(χ2=7.058,P<0.01). Among 1790830 new students tested for LTBI, the infection rate was 3.09% (55313/1790830). Among the 8104 students eligible for preventive treatment, 13.73% (1113/8104) took such treatment, and 925 completed the whole course, resulting in an 83.11% completion rate, two of the new students who did not complete the treatment became active tuberculosis patients during the treatment period. Conclusion: In Sichuan Province in 2022, the screening rate for LTBI was high among newly admitted students, however, the detection rate of LTBI was relatively low, and the proportion of LTBI students receiving preventive treatment was not high.
