Richard Skolnik, lecturer for Yale's Essentials of Global Health course, covers the state of child health worldwide in this session from the course's module on cross-cutting global health themes. He reviews leading causes of child mortality and illness, tracks progress on reducing under-five deaths, and explains why childhood immunization gets treated as its own priority area within global health work. The lecture ties child health outcomes to broader determinants covered elsewhere in the module, including nutrition, environment, and humanitarian emergencies, showing how these factors compound risk for children in low-resource settings. Skolnik presents data on regional disparities and outlines the major interventions, from vaccination campaigns to nutrition programs, that have driven improvements in child survival over recent decades. Running twenty five minutes, it functions as a compact overview aimed at students building a working knowledge of the field's core statistics and intervention strategies rather than a deep dive into any single disease or country case.
