Health Epidemiology

Health is an essential factor for all human beings. For all humans, health is a critical factor. An individual's ability to meet life's challenges and retain his or her capacity for optimal functioning is reflected in his or her condition of health. This needs the physical, mental, and biological parts of one's constitution to maintain a degree of functioning that has a favorable influence and support for one another.
