Abstract

Abstract:

Objective To analyze the tuberculosis (TB) screening situation of undergraduate freshmen and follow-up during undergraduate study in Haidian District of Beijing from 2011 to 2015. Methods A total of 266770 undergraduate freshmen from 30 universities in Haidian District of Beijing from 2011 to 2015 were selected as the survey objects. All the TB screening work was carried out in Haidian District, Beijing. The basic information and TB screening information were collected and analyzed, including tuberculin pure protein derivative (PPD) test results, chest X-ray examination results and follow-up information. Results Of the 266770 respondents, 263021 completed TB screening. Among 262742 who completed PPD screening, the strong positive rate of PPD was 5.46% (14357/262742). A total of 189 cases with TB were detected in the freshmen who received TB screening, and the detection rate was 71.86/100000 (189/263021). During the 4 years of undergraduate education, 423 cases were diagnosed with TB cumulatively, with a cumulative incidence rate of 158.68/100000 (423/266581). Freshmen with a strong positive PPD test for admission screening had the highest cumulative incidence (576.00/100000 (82/14236)) during the undergraduate period. During the undergraduate period, there were 28 cases of tuberculosis clustering epidemic, 4751 close contacts were screened, 69 patients were detected, and the recurrence rate was 1.45% (69/4751). Conclusion Universities should strengthen the mobilization of TB screening for freshmen, improve the completion rate of TB screening for freshmen, strengthen the symptom monitoring of strong PPD positive students in school, strengthen the management of rest and resumption of school for patients with confirmed tuberculosis, and timely screen close contacts.
