Public health is a field that connects science, social awareness, and civic responsibility. It emphasizes the well-being of communities through education, environmental management, disease prevention, and effective health administration. In this book, these principles are explained in an orderly and progressive manner—starting with fundamental definitions and concepts, and gradually moving toward more advanced applications in real-life health systems, policies, and hygiene practices.
