"The wellness-illness continuum is used to categorize individuals into distinct health categories, such as healthy or sick."

"The wellness-illness continuum is a model that shows a person's health moving between complete wellness and complete illness in a linear fashion."

"The continuum recognizes that health is multidimensional and includes physical, mental, and social well-being."

"The wellness-illness continuum focuses on a person's ability to stay completely well without any variations in health status."
