Health For All is a goal of the World Health Organization (WHO), that has been popularized since the 1970s and which envisions securing the health and well being of people around the world. It is the basis for the World Health Organization's primary health care strategy to promote health, human dignity, and enhanced quality of life. Halfdan Mahler, Director General (1973-1983) of the WHO, defined Health For All in 1981, as follows: Health For All means that health is to be brought within reach of everyone in a given country. And by "health" is meant a personal state of well being, not just the availability of health services – a state of health that enables a person to lead a socially and economically productive life. Health For All implies the removal of the obstacles to health – that is to say, the elimination of malnutrition, ignorance, contaminated drinking water and unhygienic housing – quite as much as it does the solution of purely medical problems such as a lack of doctors, hospital beds, drugs and vaccines. Health For All means that health should be regarded as an objective of economic development and not merely as one of the means of attaining it. Health For All demands, ultimately, literacy for all. Until this becomes reality it demands at least the beginning of an understanding of what health means for every individual. Health For All depends on continued progress in medical care and public health. The health services must be accessible to all through primary health care, in which basic medical help is available in every village, backed up by referral services to more specialised care. Immunisation must similarly achieve universal coverage. Health For All is thus a holistic concept calling for efforts in agriculture, industry, education, housing, and communications, just as much as in medicine and public health. Medical care alone cannot bring health to in hovels. Health for such people requires a whole new way of life and fresh opportunities to provide themselves with a higher standard of living.
