Public Health and Disease Management

Health, as defined by the World Health Organization, is a condition that “precedes death”. It is also said that health is wealth and the ability to carry on with day to day activities, including those related to longevity. Various definitions have been employed over the years for various purposes. For instance, one definition of health is “the ability to live a normal and healthy life despite limitations”. Another says that “life expectancy” is the maximum number of years at risk for death.


The objective of the World Health Organization is to promote healthy living through a set of standards and guidelines. These include basic information on nutrition, physical activity, and screening and preventive measures. In order to achieve health, an individual should be aware of his or her surroundings and of the occupational hazards that he or she may be exposed to. A person who is healthy and does all the necessary things in his or her capacity to avoid risks or to protect against disease, may live longer than one who is unhealthy but is prone to disease or injury. In some ways, occupational health problems are solved when people are aware of the risks they face and take steps to protect themselves from them.

Health problems can either be preventable or controllable. Control, however, cannot be done without taking care of the body. An individual who is healthy will always try to avoid disease and injury if possible, while he or she will become more prone to diseases if his or her health problems are not taken care of. It is not easy to maintain a good health status or a healthy lifestyle. But people are advised to take good health care, and this involves taking care of their bodies from exposure to diseases and injury, while they also seek preventive measures.

Mental health problems affect the ability to function normally in society. When persons are unable to perform basic functions in their lives, such as earning a living, looking after their children, working and keeping an eye on the household, they become mentally ill. Mental illness includes disorders like depression and schizophrenia. Some mental illnesses are long term; others may manifest themselves suddenly. It is important for persons to seek help when they realize they have a mental illness and consult psychologists to deal with the problem.

The main article continues; “In conclusion, physical well-being and mental health are interdependent. Poor health leads to poor well-being.” Therefore, when persons have physical problems, they are at risk of getting ill or even dying. They need to take time to look after their health, especially when these problems are caused by other factors. For instance, persons who work in industries that expose them to a variety of chemicals should take time to have regular check – ups.

This article aims to give a brief introduction about the concepts used in the study of public health and disease management. These concepts are also relevant to persons of all ages, since they have to make informed decisions on their lifestyle and their participation in public life. In fact, these concepts have become more relevant with the passage of time, particularly in today’s world where people face more challenges on a daily basis. In this world, people have become more physically active and have taken up different forms of recreation. Therefore, it is imperative for everyone to have a healthy life course.
