Every year, an estimated 15 million babies are born preterm – before 37 weeks of pregnancy. That is more than 1 in 10 live births. Approximately 1 million children die each year worldwide due to complications from their early birth. Those that survive often face a lifetime of ill-health including disability, learning difficulties, and visual and hearing problems. Half of the babies born at or below 32 weeks (2 months early) die in low-income settings, due to a lack of feasible, cost-effective care, such as warmth, breastfeeding support, and basic care for infections and breathing difficulties. In high-income countries, almost all these babies survive.
