Tuberculosis killed 1 of every 150 persons in the general population in cities such as London, Stockholm, New York, Hamburg, Taipei, and Tokyo in the late 18th, early 19th, and late 19th century. Presently, the level is more than 100 times lower. The rate of decline has recently slowed or stopped. As tuberculosis declines in the community, it becomes a disease of subgroups who either have been previously infected (immigrants), whose immunity is reduced (AIDS, silicosis, or diabetes patients) or among whom transmission continues at a high rate (in urban slums). In Canada, 80% of all cases arise among high-risk groups in whom the notification rate is over 10 times higher than in the general community. The most important of these groups are immigrants. From 1970 to 1990, the proportion of cases among immigrants to Canada rose from 20% to 50% of all cases. The explanation for the rise in the proportion was the change in source of immigrants to Canada from mostly Europeans in 1965 to mostly Asians in 1975. The record of tuberculosis in developing countries has not been as positive as in industrialized countries due to the inability to achieve satisfactory treatment in patients with active tuberculosis. Recently, within cost-effective tuberculosis programs developed by the International Union Against Tuberculosis and Lung Disease in collaboration with Tanzania, Malawi, Mozambique, Benin and Nicaragua, and with Norway, Switzerland, and the Netherlands as donor partners, more than 70,000 cases of tuberculosis are diagnosed and treated per year, and more than 75% are cured. The strategy of fighting tuberculosis includes the proper education of health care workers in developing countries; in industrialized countries focusing attention on the high risk groups and the care and prevention of tuberculosis; and preventive chemotherapy.
