Development is a multidimensional process that involves improvements in the well-being of individuals, societies, and nations. It is a broad concept that encompasses economic, social, political, cultural, and environmental progress.

In terms of economic development, good health reduces the burden of disease and improves labor productivity. People who are in good health are able to work more effectively, generating more wealth for themselves and for the economy as a whole. The absence of diseases such as malnutrition, HIV/AIDS, or malaria can prevent absenteeism and early deaths, which otherwise would drain resources and hinder economic progress. For instance, countries that have invested in improving maternal and child health have seen improvements in their economic output, as healthier populations can contribute more effectively to the workforce. Health also plays a central role in achieving human development. According to the Human Development Index (HDI), health indicators, especially life expectancy, are an essential measure of development. Access to basic healthcare services, nutrition, and sanitation are necessary for ensuring that individuals can lead healthy and productive lives. Malnutrition, particularly in developing countries, impairs
