Sustainable programs are critical for several reasons. First, they ensure the long-term viability of health interventions by making optimal use of resources. Second, they help in maintaining and improving public health, thereby reducing the burden of diseases. Third, sustainable programs are usually more cost-effective in the long run, as they minimize the need for repeated investments. Lastly, they contribute to health equity by ensuring that interventions are accessible to all segments of the population, including the most vulnerable.
