Until 1977, the incidence of lung disease due to Mycobacterium kansasii in Japan was as low as 0.11 or fewer per 10(5) people per year. It began to increase from 1978, reaching 0.33 per 10(5) people per year in 1981. In contrast, the incidence of lung disease due to the M avium-M intracellulare complex was 1.22 to 1.69 per 10(5) people per year from 1977 to 1981. In 1977, the fraction of the disease due to M kansasii in all atypical mycobacterioses was 6.9 percent, while in 1981 it increased to 19.5 percent. Concurrent with this increase, the disease spread all over west Japan, although until 1977 the disease had been restricted almost entirely to Tokyo and its environs. This change of the epidemiologic state of atypical mycobacteriosis seems to be related to the decrease of the incidence of lung tuberculosis.
直到1977年，日本堪萨斯分枝杆菌所致肺部疾病的发病率低至每年每10万人0.11例或更少。从1978年开始上升，1981年达到每年每10万人0.33例。相比之下，1977年至1981年期间，鸟分枝杆菌-胞内分枝杆菌复合体所致肺部疾病的发病率为每年每10万人1.22至1.69例。1977年，堪萨斯分枝杆菌所致疾病在所有非典型分枝杆菌病中所占比例为6.9%，而在1981年增至19.5%。随着这一比例的上升，该病蔓延至日本西部全境，尽管在1977年之前该病几乎完全局限于东京及其周边地区。非典型分枝杆菌病流行病学状态的这一变化似乎与肺结核发病率的下降有关。
