WHO urges scale up of newborn screening to improve early detection and care of birth defects

In low- and middle-income countries, nine out of ten children with serious birth defects face a future where a preventable disability or death becomes their reality—a gap the World Health Organization is now urging a global mission to close through systematic newborn screening.

A Data-Driven Call to Action

The WHO’s new report quantifies a critical disparity in global child health. An estimated eight million babies are born with a birth defect annually, with these conditions now accounting for nearly 8% of all deaths in children under five. The organization’s analysis pinpoints a clear lever for change: early screening. The report argues that for conditions like congenital hypothyroidism, sickle-cell disease, and hearing impairment, timely identification post-birth catalyzes treatments that can save lives and drastically reduce lifelong disability. The call is for governments to prioritize integration of screening into routine health services, starting with conditions feasible for their national context.

The Scale of the Screening Gap

The disparity between nations is stark. While some screen newborns for over 50 conditions, others lack the capacity to screen for any. This gap has measurable consequences. Between 2000 and 2023, birth defects accounted for a growing proportion of under-five deaths in sub-Saharan Africa and South Asia—a shift partly reflecting progress against infectious diseases, but also highlighting the rising relative burden of congenital conditions. The WHO report underscores that 90% of affected children are born in regions where diagnostic and treatment infrastructure is most limited, making scalable, low-cost screening protocols an urgent optimization challenge for health systems.

Proof-of-Concept at Scale

The report moves beyond theory, showcasing operational models that have successfully integrated newborn screening. India’s national program, for example, has screened over 28 million children in three years, identifying approximately 900,000 with birth defects and connecting them to a care pathway. In the Philippines, a pilot in 24 hospitals has scaled to over 7,000 facilities nationwide, screening for 29 conditions under a mandate backed by national health insurance. These examples provide a blueprint: begin with one priority condition, build the diagnostic and management pathway, and then expand. The WHO’s framework suggests this phased, evidence-based approach is the most viable route to universal coverage, turning early detection from a privilege into a standardized component of neonatal care. The future impact is projected in averted disabilities and saved lives, measurable at the population level.
