[An approach to the mode of case findings of pulmonary tuberculosis in countryside].

Through basic health care network, the mode of symptomatic case finding was adopted to discover, treat and supervise pulmonary tuberculosis patients in countryside. The results showed that its outstanding advantages were high detection rate (13.2%), high proportion of initial treated cases (98.2%), high curative effect and low expenses. The detection rate of smear-positive patients (48.5%) was much higher than that of other case finding modes (P less than 0.05). Sputum conversion was seen in all smear positive cases. They were cured after regular treatment.
