National health insurance, also known as universal healthcare, is an essential aspect of any progressive society. It ensures that all citizens have access to medical services without financial constraints. Synonymous terms for national health insurance include public health care, government-funded healthcare, and state-sponsored medical coverage. These names denote a system in which the government takes responsibility for financing and managing healthcare services. Such a system promotes equity, as it removes the burden of healthcare costs from individuals and redistributes it across the population. National health insurance systems exist in various forms worldwide, providing quality medical care for citizens, irrespective of their socioeconomic status.
