The ADA protects individuals with disabilities. An individual with a disability is defined as a person who has a physical or mental impairment that substantially limits major life activities; has a record of such an impairment; or is regarded as having such an impairment. “Major life activities” means functions such as caring for one's self, performing manual tasks, walking, seeing, hearing, speaking, breathing, learning and working.
Physical or mental impairments include, but are not limited to: visual, speech, and hearing impairments; mental retardation, emotional illness, and specific learning disabilities; cerebral palsy; epilepsy; pulmonary disorders; muscular dystrophy; multiple sclerosis; orthopedic conditions; cancer; heart disease; diabetes; and contagious and noncontagious diseases such as tuberculosis and HIV (whether symptomatic or asymptomatic).
