近年来初老和老年人肺结核逐年增加已受到关注。据全国各地肺结核流行学调查,老年人是肺结核病患病率的高峰,并认为者年肺结核病患病率并不因使用化疗而相应的减少,相反,老年肺结核病患者相对数随着增龄而递增。50～65岁患病率居首位,其原因是多方面的:老年人免疫力低下,易受结核菌感染或内源性旧灶复燃等。须着重指出,老年慢性纤维空洞型肺结核(IV型)已成为人群中重要的传染源。
In recent years, primary and elderly tuberculosis increased year by year has drawn attention.

On the contrary, the relative number of elderly patients with tuberculosis increases with age Increment. The prevalence of 50 to 65-year-old ranks first, for many reasons: the elderly immunocompromised, susceptible to TB infection or endogenous recurrence of old stoves and so on. It is important to note that elderly chronic fibrous hollow tuberculosis (IV) has become an important source of infection among the population.
