The World Health Organization (WHO) calls on countries to scale up newborn screening for birth defects, arguing that earlier detection improves outcomes and reduces lifelong disability. WHO says many conditions can be treated successfully if identified soon after birth, citing congenital hypothyroidism, sickle-cell disease, hearing impairment, and some metabolic disorders. However, it says millions of children are diagnosed too late or do not receive treatment.
WHO estimates that around 8 million babies are born with a birth defect each year, and that birth defects account for nearly 8% of deaths among children under five. WHO also notes that about 90% of children with serious birth defects live in low- and middle-income countries, where access to screening, diagnosis, and treatment remains limited. It highlights disparities in screening coverage, with some countries screening for more than 50 conditions and others unable to screen for any.
In a new WHO report, “Strengthening capacity for newborn screening, diagnosis and management of birth defects,” WHO encourages countries to begin with priority conditions and progressively expand. The report also points to examples of countries integrating screening into routine services, including programs in Argentina, Brazil, Egypt, India, the Philippines, Sri Lanka, and Uganda, aiming to connect screening to diagnosis, treatment, and follow-up care through national health systems.
