What defines a state of complete physical, mental, and social well-being?

The concept of complete physical, mental, and social well-being is best encapsulated by the term health. According to the World Health Organization (WHO), health is not merely the absence of disease or infirmity but a holistic state that includes physical fitness, mental stability, and the ability to form and maintain social relationships. This comprehensive definition recognizes the interconnectedness of various dimensions of well-being, emphasizing that optimal health involves more than just a lack of illness.

Hygiene and sanitation pertain to practices and conditions that promote health by preventing disease, but they do not encompass the broader aspects of well-being. Infection control focuses specifically on preventing the spread of infectious diseases and is a critical component of health care; however, it does not represent the entirety of what it means to be healthy. Thus, health is the most accurate choice as it aligns with the holistic view of well-being.
