Healthcare refers to the maintenance or improvement of health through the prevention, diagnosis, treatment, and recovery of illness, disease, injury, and other physical and mental impairments in individuals. It encompasses various services provided by medical professionals, healthcare facilities, and organizations to ensure the well-being of individuals and communities.
The key components of a healthcare system include:
Healthcare systems can differ in terms of financing, delivery, and access to services. Some countries have universal healthcare, while others rely on private insurance and out-of-pocket payments.
Public health focuses on promoting and protecting the health of entire populations through initiatives such as disease prevention, health education, and policy development.
Challenges include access to care, healthcare disparities, rising costs, and the aging population.
