According to the study, four communicable disease categories account for 54 percent of all child deaths globally. Pneumonia accounts for 19 percent of all child deaths, diarrhea 17 percent, malaria 8 percent and neonatal sepsis 10 percent. Undernutrition is an underlying cause in more than half of all deaths before age 5. More than 37 percent of all child deaths occur during the first 28 days of life, the neonatal period. The researchers noted that child mortality is greatest in Africa. The study shows that 42 percent of child deaths under age 5 occur in Africa, which is also where 94 percent of all child deaths attributed to malaria occur.
"Achievement of the WHO's goal of reducing child mortality by two-thirds from the 1990 rate will depend on renewed efforts to prevent and control pneumonia, diarrhea, and undernutrition in all regions, and malaria in the Africa region," said Robert Black, MD, MPH, professor and chair of the Department of International Health at the Bloomberg School of Public Health. Dr. Black chaired the WHO Child Health Epidemiology Reference Group, which developed the new estimates by analyzing data and developing statistical models from previous publications and ongoing studies. The estimates cover a period from 2000 to 2003.
"In all regions of the world, deaths in the neonatal period, primarily due to preterm delivery, sepsis or pneumonia and birth asphyxia, should
