The first forty years: a personal view.

Discussed below are some of the great public health issues and trends of the period that has elapsed since the foundation of the World Health Organization. They were dominated by the new Malthusian nightmare, the tussle with malaria, the eradication of smallpox, the improved control of some other serious infections, the struggles for family planning, breast-feeding, immunization, and clean water, among other things, and above all, perhaps, by the decline of the doctor and the rise of the planner and manager. More recently there have been the policy changes affecting international health which came from the Declaration of Alma-Ata, and the emergence of primary health care.
