Infant mortality
Premature birth is the biggest contributor to infant deaths. Other leading causes of infant mortality are birth asphyxia, pneumonia, congenital malformations, term birth complications such as abnormal presentation of the foetus umbilical cord prolapse, or prolonged labor neonatal infection, diarrhea, malaria, measles and malnutrition. In 1900, 30 percent of all deaths in the United States occurred in children less than 5 years of age compared to just 1.4 percent in 1999.
