Furthermore, due to factors such as the presence of other chronic illnesses and weakened overall resistance to disease, the elderly are the group with the highest incidence of TB. Currently, of the 19,000 reported suspected cases of tuberculosis in Taiwan, 46 % are among persons aged 65 or older.
此外，由於伴隨許多其他慢性疾病、抵抗力較弱等因素，老年人是結核病罹病率最高的族群，目前台灣一萬九千個疑似結核病的通報病例中，百分之四十六是六十五歲以上的老人。
