Preventive and Social Medicine (PSM), also known as Community Medicine or Public Health, is a course that focuses on the health of populations rather than individuals. It emphasizes the prevention of diseases, the promotion of health, and the prolongation of life through organized efforts and informed choices of society, organizations, communities, and individuals. The course integrates knowledge from various disciplines, including epidemiology, biostatistics, environmental health, occupational health, nutrition, and health education, to understand and address health issues at the community level. Students learn to assess health needs, design and implement health programs, and evaluate their outcomes. The course also covers national health programs, public health laws, health policies, and health systems management. By focusing on prevention and early detection of diseases, PSM plays a vital role in reducing the burden on curative services and improving the overall quality of life. It aims to equip future healthcare professionals with the skills necessary to plan, execute, and monitor public health strategies and interventions for the betterment of society.
