Abstract

The number of tuberculosis (TB) cases in schools is decreasing annually. TB cases in schools decreased by 7.9% (77 cases) compared to 2018; however, in 2020 during the the coronavirus disease 2019 (COVID-19) pandemic, it decreased by 29.6% (267 cases) compared to 2019, the largest decrease. Compared to 2018, the number of tuberculosis patients in high schools in 2021 decreased by 54.1% (132 cases) and universities by 46% (203 cases). The number of TB cases aged 13?15 and 16?18 years old, middle and high school students, decreased by 52.3% (34 cases) and 60.7% (133 cases), respectively, but only 6.6% (4 cases) for those aged 60 and older. The incidence of TB in children under elementary school age was less than 1 per 100,000 students which was low regardless of the COVID-19. The incidence rate of high school and college students dropped to less than 10 per 100,000 students after 2020 and were 6.2 and 6.4 in 2021, respectively. Although the incidence of TB among faculty and staff continues to decrease, there remains a large gap in the TB incidence between faculty and students. The rate of TB screening among TB patients attending schools declined from 44.1% in 2019 to 39.2% in 2020, when the COVID-19 pandemic peaked. In particular, the proportion of TB cases detected through health screening among college students continues to decrease. It is necessary to closely monitor the epidemiological characteristics of TB patients in schools, and the early detection of TB by regular health screening is important to minimize TB transmission in schools.
