Final answer:
Disability refers to an impairment that limits major activities and may result in stigmatization or discrimination. It encompasses both physical limitations (impairment) and social limitations (disability). People with disabilities can face discrimination and limited opportunities, but increasing visibility and education can bring about positive change.
Step-by-step explanation:
Disability refers to an impairment that substantially limits one or more major activities that a person would normally do at a given stage of life and that may result in stigmatization or discrimination. The World Health Organization distinguishes between impairment and disability, where impairment refers to physical limitations and disability refers to the resulting social limitations. People with disabilities can face stigma, discrimination, and limited opportunities for healthcare, education, and employment. Increasing visibility and education about disabilities can help bring about positive social change.
