Tuberculosis: Old Disease, Continuing Threat
The "rest cure" - an extended stay in a sanatorium, or TB hospital, away from home and family - was the only hope for tuberculosis patients in the first half of the 20th century. Then came a cure for the dreaded lung disease: powerful antibiotics that made the sanatorium a thing of the past. But TB was far from eradicated, and new drug-resistant strains surfaced in the 1980s, threatening vulnerable groups such as the urban poor and northern aboriginals. Now, over half of new TB cases in Canada are found in newcomers, and Canadian scientists are at the forefront of new treatments for the disease.
