Abstract

Abstract

Objective To understand the management of tuberculosis outbreaks in middle schools in Bijie City, and to put forward suggestions to improve the quality of tuberculosis epidemic situation in schools. Methods A unified questionnaire was used to investigate the management of tuberculosis outbreaks in middle schools reported by tuberculosis information management system from August 27, 2018 to January 6, 2019 in Bijie City. Results The screening rate of close contacts was 69.72%(99/142), which significantly varied by counties(P < 0.01). The time from the date of diagnosis of patients to screening of close contacts by local CDC was 3(1-10.5) days. Rate of standardized management process for close contacts aged 15 years or older (0) was lower than that for close contacts aged younger than 15 years old (23.08%)(P < 0.01). 3 462 close contacts were screened for TB symptom, and chest X-ray among those suspected individuals(process 1), and 2 439 close contacts were screened with TB symptom, PPD test, and chest X-ray among those suspected individuals or those with strong positive in PPD test(process 2). The detection rate of pulmonary tuberculosis in close contacts of Grade I was lower in Process 1 (28.89/100 000) than in Process 2 (328.00/100 000)(χ²=6.56, P=0.01). The latent infection rate of the first-class close contacts (6.39%) was higher than that of the second-class close contacts(1.93%)(χ²=54.86, P < 0.01). Conclusion Management of tuberculosis outbreaks in middle schools in Bijie City in 2018 is effective and timely, but the standardization needs to be improved.
