Dye and his colleagues reported that, with the exception of Africa and Eastern Europe, WHO can achieve its goals with increased application of the Directly Observed Treatment Scheme (DOTS), a public health strategy that includes gaining political commitment, detecting cases based on sputum smear microscopy, utilizing standard short-course therapy with supportive patient management, ensuring regular drug supplies, and standardizing systems for recording cases and reporting outcomes (JAMA 2005;293:2767-75).
