Selective primary health care: strategies for control of disease in the developing world. IX. Poliomyelitis.
Poliomyelitis is an acute viral disease primarily afflicting children. It can be very mild, permanently crippling, or fatal. In the developed nations, poliomyelitis is controlled by the use of trivalent vaccines: killed virus administered by injection and/or attenuated virus administered orally. The latter is cheaper. A combination of the two may be required in some tropical countries. In many developing nations poliomyelitis remains endemic and prevalent, especially in children; 37,747 cases were reported to the World Health Organization in 1979, but greater than 200,000 cases probably occurred. Socioeconomic improvement and public health measures (i.e., immunizations) remain the major strategies for control. While global eradication may be a more distant goal, poliomyelitis could be controlled better. Effective programs for control include safe, efficacious, and inexpensive vaccines; methods for successful management of vaccine delivery systems; commitment and training of health personnel; public education; commitment of funds; and research to improve vaccines and their delivery. The major obstacle to control of poliomyelitis is failure to immunize an adequate number of susceptible children. Development of strategies for immunization is crucial to elimination of poliomyelitis as a major world health problem.
