The WHO constitution for a healthy world came into force on April 7, 1948. It defines health as complete physical and mental well-being. The writers of the constitution were aware of the tendency for people to view health as an absence of diseases. They wanted to define health as a resource for everyday life, not merely a condition that is present for a period of time. The term “health” is not solely limited to the physical senses, though; mental and emotional well-being play an important role, as well.
Public health is concerned with the general health of a community. It aims to prevent and treat disease by educating residents, promoting healthy diets and lifestyles, and encouraging vaccinations. It also helps to protect the environment by encouraging clean water and condoms. Infectious diseases may require individuals to wash their hands for 30 seconds before touching surfaces, wear surgical masks to avoid the spread of infection, and avoid mass gatherings. Moreover, public and occupational health is a societal concern that affects many aspects of everyday life.
Public health focuses on preventing disease. It involves preventive measures to keep people healthy, and it promotes regular checkups and vaccinations. It also encourages the use of condoms and hygienic practices. In some cases, a disease might require a person to wash their hands thoroughly, or they may be advised to avoid large crowds, or to wear a surgical mask. Ultimately, health is about the way a body adapts to physical changes and the ability to maintain good physical and mental well-being.
