Health insurance, also known as "sickness insurance". Refers to the life insurance in which the insurer pays insurance money to the insured when he is ill. The payment scope of health insurance usually includes medical expenses, income loss, funeral expenses and living expenses of survivors. This kind of insurance is mostly co-organized with injury insurance and life insurance. In order to prevent moral hazard, the insurer usually stipulates a trial insurance period when handling health insurance. After this period, the insurer will be liable for the losses caused by the insured's illness.
