本文通过对20209名肺部无活动性病灶的成年健康者的连续四年发病观察结果,证明占成年人群6.5％的未治疗和治疗不充分纤维病灶者的肺结核发病率比治疗充分纤维病灶者和无纤维病灶者高10倍以上,他们是成年人群中的主要高发对象,应予重视。占成年人群2.0％左右的已完成正规化疗纤维病灶者的发病率接近无纤维病灶人群,因此对他们不必再进行随访观察。 In this paper, the results of 20209 consecutive 4-year incidence of adult patients with no active lung lesions showed that the incidence of pulmonary tuberculosis in 6.5% of the untreated and under-treated fibrous lesion in the adult population was higher than those in the treatment of adequate fibrosis No fiber lesions were more than 10 times higher, they are the major high incidence of adult population, should be valued. Adults who account for about 2.0% of those who have completed the formal chemotherapy fibrosis incidence rate close to those without fibrosis, so they no longer have to follow-up observation.
