Medical Sociology is the branch of Sociology that uses sociological concepts and analytical tools to examine the context of health and illness at the micro, meso and macro levels. It researches medicine as a social institution, its relationship to other institutions, the relationships between patients and health professionals, and sociological perspectives of contemporary health care. According to World Health Organization, health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity(1946). In this course, our focus will be on a sociological perspective that emphasizes: social concepts of health and well-being, social determinants of health, inequalities in health, and so on.
