Abstract:

On December 7, 2020, the Wugang City Center for Disease Control and prevention (subordinate to Shaoyang City) received the early warning information of a high school student Deng diagnosed as active tuberculosis. On the same day, Wugang Center for Disease Control and prevention organized professionals to go to hospitals and schools to carry out investigation. A total of 14 cases of student pulmonary tuberculosis were detected, with 2 males and 12 females, and an average age of (16.07±0.48) years. A total of 1194 contacts were screened, of which 144 were strongly positive by tuberculin skin test (TST), with a strong positive rate of 12.06%. Among them, 13 patients were found, with an incidence rate of 1.09%; 130 patients with strong positive TST received TB preventive treatment, and there was no incident case; 14 strong positive patients did not receive preventive treatment, and 5 cases developed disease.When the outbreak happened, the contacts should be screened in time, and those with strong PPD should take preventive treatment, which is conducive to the control of school tuberculosis.
