Abstract

Objective To understand the prevalence and development of pulmonary tuberculosis (PTB) in students and teachers in Liangyungang over the last ten years, and provide reference for PTB surveillance and control at schools and colleges.

Methods The epidemic information of PTB among students and teachers in Lianyungang during 2008-2017 was collected from Chinese Infectious Disease Report Information Management System and Chinese Tuberculosis Information Management System, and analyzed with quantitative description method.

Results From 2008 to 2017, 1 112 students and teathers with PTB were found in Lianyungang City, the average reported incidence was 14.03/100 000, pathogenic positive incidence was 4.52/100 000. The above two rates both showed a trend of decline year by year ( Z = 4.55, 6.83, P<0.01). The incidence of registered PTB in schools in the second quarter was the highest, especially in April. Guanyun County has the highest incidence. The average age was (20.11±7.54) years old, and the obvious high-incidence age group was 16-21; the sex ratio between men and women was 1.87 : 1. Most of the 1 112 patients were Han, accounting for 99.64%, the rest were Hui, Tujia and Uygur. Teachers’ reported incidence was positively correlated with students’ reported morbidity ( r _s =0.93, P<0.01); there were differences between school population and general population in gender, patient origin, etiological results, treatment classification and positive patients’ treatment outcome ( χ ² = 49.54, 528.27, 63.55, 121.40, 9.80, P<0.05).

Conclusion Overall, the reported incidence of PTB in schools in Lianyungang City has been decreasing year by year, however, it should not be taken lightly. Prevention and control of PTB in schools should be further strengthened.
