Social medicine is concerned with how social and economic factors impact health and disease. It aims to understand these relationships and create conditions for a healthier society. Socialized medicine describes universal healthcare systems funded through taxation where medical care is available to all at low cost. Pros include affordability, uniform access to care regardless of income, and healthcare for all citizens. Cons can include potentially lower quality care, decreased medical innovation, and increased tax burden. Some countries with socialized medicine systems are described. In India, various state-run health insurance schemes have been launched to provide socialized care.
