1979年全国结核病流行病学调查888个点1,295,083人群的调查结果:0～29岁的人数,占调查总人数的64.8％,其中活动性肺结核占28.5％,痰中检出结核菌的占21.3％;45岁以上的人数,占调查总人数的19.4％,占活动性总人数的53.6％,占痰菌阳性的54.2％。说明老年人结核占人群的百分率比较高,传染性比较大,危害性也大。从全国流调的资料还可看出:65岁以上的肺结核患者是0～14岁患者的8～24倍。为什么老年人结核病多了?归纳起来有三个因素。(1)中青年时代患肺结核病后,病未治愈,进入老年。(2)老年人合并糖尿病、癌症等消耗性疾病的百分比高,降低了人体抵抗力,容易害结核病。(3)原有肺结核病,老年时抵抗力差了,旧病复发。
Survey of Epidemiological Survey of Tuberculosis in 1979 888 points 1,295,083 population surveyed: 0 ~ 29 years old population, accounting for 64.8% of the total survey population, of which active tuberculosis accounted for 28.5%, sputum sputum detection of TB accounted for 21.3% ; Those over 45 years of age accounted for 19.4% of the total number of people surveyed, accounting for 53.6% of the total number of active persons and 54.2% of those who were sputum positive. This shows that the percentage of elderly people living in tuberculosis is relatively high, infectious, and harmful. Data from the national epidemic can also be seen: more than 65 years of age tuberculosis patients are 0 to 14-year-old patients 8 to 24 times. Why is the elderly more tuberculosis? Summarized with three factors. (1) young and middle-aged patients suffering from tuberculosis, the disease is not cured, into the elderly. (2) Elderly people have high percentage of consumptive diseases such as diabetes mellitus and cancer, which reduces the body’s resistance and easily causes tuberculosis. (3) The original tuberculosis, poor resistance in old age, old disease recurrence.
