Abstract: Objective: To analyze the tuberculosis infection and prevalence among all teachers and students of primary and secondary schools in the third divisions of Xinjiang Production and Construction Corps.Methods: According to the requirements of notice on carrying out tuberculosis screening on school students, the Center for Disease Control and Prevention of the third division carried out tuberculosis infection screening in its jurisdiction, for 34066 teachers and students of primary and secondary school from March to May 2020, including suspected symptoms of pulmonary tuberculosis, tuberculin skin test (TST), sputum smear and chest X-ray examination.Results: Of all the subjects, 2068 were positive, the positive rate was 6.07%, and 302 were strong positive,the rate was 0.89%. With the increase of students’ grade,the positive rate and strong positive rate increased from 5.23% (1174/22463) and 0.38% (85/22463) in primary school group to 10.34% (206/1993) and 3.36% (67/1993) in high school group, respectively, the differences were significant (χ²=91.92 and 245.01, respectively, both P<0.001). The positive rate and strong positive rate of faculty were significantly higher than those of students (13.70% (158/1153) vs. 5.80% (1910/32913),χ²=121.93, P<0.001; and 3.04% (35/1153) vs. 0.81% (267/32913),χ²=62.73, P<0.001, respectively). The strong positive rate of Uighur teachers and students was significantly lower than that of Han teachers and students (0.74% (162/21878) vs. 1.15% (140/12188),χ²=14.84,P=0.001). Sputum smear and chest X-ray examination were performed on 302 teachers and students who were strong positive. Five students with abnormal chest X-ray were diagnosed as active pulmonary tuberculosis patients, 18 teachers and students with strong positive in close contact took preventive medicine.Conclusion: The strong positive rate of TST increased with the increase of students’ grade. TST screening should be carried out regularly for senior students, which played an important role in mastering the recent infection of tuberculosis and preventing the occurrence of school aggregated tuberculosis.
