This special issue on Newborn Health in Global Health Action is being launched to share the experience of how to scale up a cost-effective package of newborn care that involves families, community health workers and health facilities. The results of this community randomized trial, the Uganda Newborn Study (UNEST), show that home visits in pregnancy and soon after delivery resulted in improved breastfeeding practices, skin-to-skin care immediately after birth, delaying a baby’s first bath, and hygienic care of the baby’s umbilical cord among the poorest households with lowest access to care.
