What is Healthcare?

Healthcare is the organized system of services, professionals, institutions, and resources dedicated to maintaining, restoring, and improving physical and mental health. It includes prevention, diagnosis, treatment, and long-term care across all stages of life.

Why does Healthcare matter?
