Emergencies in international child health.
Emergencies in the pediatric populations of third world and developing countries are of a much different sort than those to which pediatricians in developing countries are familiar. Many of these emergencies derive from conditions, situations, and etiologies that no longer represent a threat to children in developed countries: malnutrition, immunizable illnesses, infectious diseases from pathogenes easily treated or prevented, urbanization, and armed conflict. Programs directed at improving basic public health, health education, access to basic health care, and immunization have been shown to have a major and positive impact on children's health status in these countries. Because of the vastness of these health problems, a growing number of volunteer organizations offer opportunities for pediatricians to contribute to improvement and they have an impact on the health of children considerably less fortunate than those in developed countries.
