Tuberculosis is one of the infectious diseases that seriously threaten human health. The number of patients with tuberculosis in China ranks third in the world. After human infection with Mycobacterium tuberculosis

some patients have no clinical manifestations and failed to take the initiative to see a doctor in time

which often leads to missed diagnosis and misdiagnosis of tuberculosis and delays the best treatment time. Some patients will have aggravated conditions or turn into bacteria-positive patients

become the source of infection

and increase the risk of disease transmission. Active screening for tuberculosis can compensate for the shortcomings of traditional passive detection methods and improve the detection rate of pulmonary tuberculosis

but it is necessary to explore cost-effective active detection models. General practitioners are the ″gatekeepers″of residents’ health

who play a vital role in tuberculosis prevention and control.
