Reducing child mortality is high on the list of the United Nations’ Millennium Development Goals
—the eight global health, economic and development benchmarks set by the U.N. in 2000 for 2015.
While mortality among children under age 5 has improved greatly, the gains have largely been among children at the older end of that grouping. When it comes to mortality in the first week of life, little has changed.
“Early neonatal mortality rates haven’t decreased in the last two decades,” says Grace Chan, MD, PhD, a pediatrician at Boston Children’s Hospital, who conducts global health research at Harvard School of Public Health. “In developing countries, they still hover near 30 deaths per 1,000 live births.”
Early-onset infections—ones that arise within a week of birth—account for a significant portion of those deaths. Such infections may arise when a newborn picks up bacteria present in the mother’s birth canal during delivery, or from maternal infections during pregnancy.
In developed countries, interventions like prophylactic antibiotics and quick diagnoses help to keep neonatal infection rates low. But these kinds of interventions are less available in developing nations, where they could have the most impact. And while risk factors for neonatal infections have been well studied in developed nations, they are less well known in resource-poor environments, where the infections most frequently occur.
To put it another way, when it comes neonatal sepsis in developing countries, there’s a lot we don’t know.
