Abstract:

Objective To provide the basis for improving the prevention and control measures of tuberculosis in schools, epidemiological characteristics of tuberculosis in dongguan schools were analyzed.Methods The total number and incidence of TB patients in schools who completed anti-TB drug treatment courses were collected from 2015 to 2017, and reported the patient’s gender, age, school distribution, disease classification, onset and education stage from the sub-systems of “Infectious Disease Report Information Management System”and “Tuberculosis Information Management System”in the Chinese Information System for Disease Control and Prevention. The whole population statistics of 2017 and before were obtained from Dongguan statistical yearbook 2017 of Dongguan municipal bureau of statistics. The demographic data of students and teachers in Dongguan city were obtained from the general table of basic conditions of various schools in Dongguan city in the academic year 2015/2016-2017/2018 issued by Dongguan education bureau. SPSS 21.0 software was used to conduct statistical analysis of demographic characteristics and disease characteristics of the data of tuberculosis patients reported by the school. P<0.05 was considered statistically significant.Results rom 2015 to 2017, a total of 224 TB patients were reported in Dongguan, and the annual reported incidence was 4.54/100000 (224/4929416). The average annual incidence of student patients (3.97/100000, 186/4682822) was lower than that of teacher patients (15.41/100000, 38/246594) (χ ²=67.45, P=0.000). From 2015 to 2017, the student reported incidence of the disease (2.85/100000 (43/1506393), 4.38/100000 (68/1554199) and 4.62/100000 (75/1622230), respectively) had an increasing trend year by year (χ ²=6.05, P<0.01). However, the teacher reported incidence of the disease (12.78/100000 (10/78219), 17.21/100000 (14/81343), and 16.09/100000 (14/87032)) did not increase year by year (χ ²=0.28, P=0.600). The ratio of male and female were 1.55∶1 (113 cases and 73 cases, respectively) and 0.65∶1 (15 cases and 23 cases, respectively), the difference was not statistically significant (χ ²=1.62, P=0.445; χ ²=0.63, P=0.730). Students aged 15-19 years accounted for 67.74% (126/186) of the total number of reported students. The proportion of patients in general middle schools was higher than that in other education stages (53.76% (100/186) vs. 46.24% (86/186))(χ ²=144.78, P<0.05). The incidence of secondary vocational and technical school students (4.30/100000 (3/69734), 17.40/100000 (13/74700), 32.38/100000 (26/80294)) showed an increased trend (χ ²=15.82,P<0.01). The reported TB in students was mainly pathogen negative (72.04%,134/186), and the incidence peak was in April (17.74%,33/186).Conclusion From 2015 to 2017, the incidence of TB reported by students increased year by year in Dongguan city, with more males than females. School TB control is focused on the secondary level, especially in high schools and vocational and technical schools.
