Definition - What does Sickness mean?
A sickness is any illness or disease that causes a person to be in a state of ill health. In the context of insurance, illnesses are conditions often covered by health insurance policies. Therefore, if a person has health insurance, they would be financially covered for the treatment of a number of specified sicknesses.
Insuranceopedia explains Sickness
An example of a sickness is pneumonia. If a person contracts it, they could miss time from work or school and require a doctor's visit for a diagnosis and prescription medication. Without health insurance, visits to the doctor's and treatments can be costly. However, a basic policy often covers a portion of the fees for such services.
