Abstract:

Objective To analyze the epidemiological characteristics of tuberculosis among teachers in Jilin Province for evidence to improve the prevention and control strategy for pulmonary tuberculosis in school campus. Methods The tuberculosis cases of teachers registered in Jilin Province from 2012 to 2021 were retrieved from the tuberculosis management information system under the China Disease Prevention and Control Information System. Then the data on the teachers, including the temporal, regional and population distribution, ways to identify the infection and the intervals of treatment, were retrospectively analyzed. Results From 2012 to 2021, there were 529 teachers registered with active pulmonary tuberculosis in Jilin Province, with an average annual registered incidence of 13.63/100 000, which showed a decreasing trend (χ2 trend=33.695, P<0.05), with an annual decreasing rate of 11.32%. The year 2017 was a dividing line for the distribution of registration time. Between 2012 and 2016, the highest number of patients registered occurred in March (36 cases, 11.36%), the lowest number was in September (16 cases, 5.05%), yet between 2017 and 2021, the highest number of patients registered occurred in September (31 cases, 14.62%) and the lowest in February (9 cases, 4.25%). The patients were mainly distributed in the central region of Jilin (241 cases, 45.56%). There were 244 males and 285 females, with a sex reatio of 1∶1.17. Most of the patients were teachers ≥50 years old (188 cases, 35.54%). The most common way of finding tuberculosis patients in teachers was self-referral due to symptom (248 cases, 46.88%). The proportion of patients identified in follow-up showed an increasing trend over time (χ2trend =15.207, P<0.05). The positive rate of etiology was 31%, which showed an increasing trend (χ2trend =29.393, P<0.05). The rate of delayed treatment was 70.51% (373 cases) for the teachers, and showed a decreasing trend (χ2trend =7.478, P<0.05). The time from the first symptom to the first treatment was 30.00 (12.00, 45.00) days. Conclusion From 2012 to 2021, the prevalence of tuberculosis among teachers in Jilin Province showed a downward trend, yet weakness still remains in timely treatment and active detection of the patients. The findings suggest that health education and physical examination should be strengthened among the teachers so as to improve active detection, reduce delayed treatment, and prevent the spread of tuberculosis in school campus.
