Developing countries, particularly the fast-growing BRIC countries, are increasingly switching their focus from economic development to social welfare, of which public health insurance is an important component.
Currently, three major health care systems exist in OECD countries: National Health Service (NHS) in Nordic countries like Sweden and Norway and commonwealth countries including the United Kingdom, Canada, and Australia; Social Security system in continental Europe including France, Germany, Netherlands, and Austria; and Private Health Insurance in the United States.
