一、结核病流行的趋势近二十余年来,结核病在世界范围内,特别是发达国家内都已减少,但在老年人中间其发病率下降最慢。在英国,结核病的最高发病率就是在65岁以上的人群内。从我国结核病流行的趋势来看,经过近三十年积极采取防治措施,疫情发生很大变化,全人口中结核病的死亡率、患病率都有显著的下降。然而,从1979年全国结核病流行病学抽样调查(简称流调)所报告的患病情况可看出,不同年龄患病率和痰菌阳性患病率曲线随年龄增长而逐步升高,65岁达最高峰,70岁以后略有下降。这个结果提示我们,我国结核病流行的趋势,老年人肺结核已处于高发年龄组的
First, the trend of tuberculosis epidemics Over the past two decades, tuberculosis in the world, especially in developed countries have been reduced, but the incidence of the slowest decline among the elderly. In Britain, the highest incidence of tuberculosis is in people over the age of 65.

The mortality and prevalence of tuberculosis in the entire population have dropped significantly. However, according to the prevalence reported by the National Tuberculosis Epidemiology Sampling Survey in 1979, the prevalence of different ages and the prevalence of sputum positive rates gradually increase with age, and the age of 65 Reaching the peak, a slight decline after 70 years of age. This result prompts us that the epidemic trend of tuberculosis in our country, the elderly have been in high-risk tuberculosis age group
