Illness insurance, also known as critical illness cover or health insurance, is a type of insurance policy that provides financial protection against the costs associated with serious illnesses. This coverage can help pay for medical treatments, hospital bills, and other expenses not covered by traditional health insurance policies. Illness insurance typically covers specific diseases such as cancer, heart attack or stroke, and may also provide a lump sum payment in case of diagnosis with one of the covered illnesses. The policy can help alleviate financial stress during an already difficult time, allowing individuals to focus on their recovery without worrying about how they will pay for medical treatments or other expenses.
