Health insurance is an insurance that covers the whole or a part of the risk of a person incurring medical expenses. International health insurance works like health insurance at home as you are not just covered for emergency treatment, but also for your diagnosis and post-treatment care. Health insurance generally covers the cost of doctors or emergency room visits, medicines, routine vaccinations and tests, surgeries, and psychological care. Depending on the type of insurance coverage you have, you may need to pay a portion of the expenses in addition to the premium you pay for general coverage.
