The influence of immigration from six selected Asian countries--Japan, Korea, Philippines, India, China and Hong Kong--on the incidence of tuberculosis in British Columbia has been examined. During the period 1982-1985 the average annual incidence of bacillary tuberculosis in these immigrants was more than six times as great as the overall British Columbia rate and contributed a quarter of the cases of active bacillary tuberculosis in this province whereas the immigrants from these countries represented only 3.7% of the total population. The clinical patterns of active tuberculosis by birthplace were analysed. A high proportion of cases of lymphadenitis was seen among all immigrants from Asia, particularly those from the Philippines. Both primary and secondary drug resistance was substantially higher than in Canadian-born patients. The frequency of primary drug resistance was higher among patients aged less than 40 years than those aged 40 or more.
已对来自六个选定亚洲国家——日本、韩国、菲律宾、印度、中国和香港——的移民对不列颠哥伦比亚省结核病发病率的影响进行了研究。在1982年至1985年期间，这些移民中细菌性结核病的年均发病率比不列颠哥伦比亚省的总体发病率高出六倍多，且该省活动性细菌性结核病病例中有四分之一是由这些移民导致的，而来自这些国家的移民仅占该省总人口的3.7%。分析了按出生地划分的活动性结核病的临床模式。在所有来自亚洲的移民中，尤其是来自菲律宾的移民中，淋巴结炎病例比例很高。原发性和继发性耐药性均显著高于在加拿大出生的患者。年龄小于40岁的患者原发性耐药的频率高于40岁及以上的患者。
