Description: Critical Illness (CI) insurance in Asia has evolved through data-driven insights, adapting to changing medical, demographic, and lifestyle trends. Gen Re’s CI Data Insights Study, covering Mainland China, Hong Kong, Singapore, Malaysia, and Thailand, highlights how advances in screening, especially for cancers, have influenced incidence rates and claims. Regular updates to CI definitions and product structures are essential for sustainability, as seen in the handling of thyroid and prostate cancers. Lifestyle factors like BMI also impact cardiovascular risk. A multi-dimensional approach combining robust data monitoring, proactive product updates, and wellness promotion ensures CI insurance remains relevant and sustainable.
