Abstract:
Objective To investigate the epidemiological characteristics of pulmonary tuberculosis among students in Fuzhou City in 2022 and the screening of their close contacts, so as to provide scientific basis for further prevention and control of tuberculosis in schools. Methods A descriptive method was used to investigate the campus tuberculosis epidemic situation in 87 colleges and universities in Fuzhou, and 96 cases of confirmed student patients were investigated individually, and 7 488 close contacts were screened according to the requirements of the Guidelines for tuberculosis Prevention and Control in Chinese Schools, and the results were analyzed. Results In 2022, a total of 96 students with pulmonary tuberculosis were found in Fuzhou City, with a male to female ratio of 1.04∶1 and an average age of 17.92 ± 4.16 years. The incidence rate of active pulmonary tuberculosis and the incidence rate of bacterial positive pulmonary tuberculosis among university and college students were higher than those among other types of schools, separately 10.56/100 000 and 5.18/100 000, with significant differences (χ2=75.22, P<0.05; χ2=38.69, P<0.05). The proportion of student patients was the highest in the first quarter (34.38%, 33/96). There were 44 cases of delayed visits, with a delay rate of 45.83% (44/96). The diagnosis was delayed in 15 cases, with a delay rate of 15.63% (15/96). Screening of 7 488 close contacts, of which 5 339 were screened with chest radiography and 5 active cases were found. A total of 7 124 patients were screened by the tuberculin skin test (TST test), the positive rates of TST test results for close contacts of pathogenic and no pathogenic patients were 25.97% (1 135/4 371) and 21.10% (581/2 753), respectively. The strong positive rates were 6.15% (269/4 371) and 3.01% (83/2 753), respectively, with statistically significant differences (χ2=21.84, P<0.05; χ2=35.44, P<0.05). Conclusion In 2022, the incidence of tuberculosis in schools in Fuzhou City was dominated by students from universities and colleges, with the highest incidence rate in the first quarter. The delay in seeing a doctor and diagnosis of student patients was serious. Timely and effective screening of close contacts (especially the close contacts of patients with bacterial positive pulmonary tuberculosis) can reduce the spread of tuberculosis in schools.
