The world is failing its youngest, with a staggering 4.9 million children dying before their fifth birthday in 2024 from causes largely considered preventable. This stark reality comes from a landmark report released by the World Health Organization (WHO), underscoring a worrying slowdown in global child survival efforts despite decades of progress.
The comprehensive "Levels and Trends in Child Mortality" report, compiled by the United Nations Inter-agency Group for Child Mortality Estimation, paints the clearest picture yet of the persistent challenges. While under-five deaths have more than halved since 2000, the pace of reduction has plummeted by over 60 percent since 2015, signaling a critical need for renewed commitment.
The Silent Killers: Preventable Causes Behind Millions of Deaths
For the first time, the report fully integrates detailed data on causes of death, revealing how malnutrition and common infectious diseases continue to claim young lives:
- Severe Acute Malnutrition: Over 100,000 children aged between one and 59 months died directly from severe acute malnutrition in 2024, accounting for approximately five percent of deaths in this age group. The true impact is likely far higher, as malnutrition severely weakens immunity, making children more vulnerable to other illnesses. Countries like Pakistan, Somalia, and Sudan bore the brunt of these malnutrition-related fatalities.
- Newborn Complications: Nearly half of all under-five deaths—a heartbreaking 2.3 million newborns—occurred within the first month of life. The primary culprits include complications from preterm birth (36 percent) and issues during labour and delivery (21 percent), alongside infections such as neonatal sepsis and congenital anomalies.
- Infectious Diseases Beyond Infancy: For children aged one month to five years, infectious diseases remain the leading cause of death. Malaria alone accounted for a staggering 17 percent of these fatalities, predominantly in sub-Saharan Africa. Progress in combating malaria deaths has regrettably stalled in recent years, especially in high-burden nations like Chad, the Democratic Republic of the Congo, Niger, and Nigeria, exacerbated by conflict, climate shocks, and limited healthcare access.
Stark Disparities: Where Children Face the Gravest Risks
The report unequivocally highlights profound geographical inequalities in child survival:
- Sub-Saharan Africa: This region accounted for a devastating 58 percent of all under-five deaths in 2024.
- Southern Asia: Contributed an additional 25 percent to the global toll.
In stark contrast, infectious diseases were responsible for only nine percent of under-five deaths in Europe and Northern America, and a mere six percent in Australia and New Zealand. These figures starkly illustrate unequal access to life-saving interventions and quality healthcare.
Children born in fragile and conflict-affected settings face an even grimmer prognosis, being nearly three times more likely to die before their fifth birthday compared to those in more stable environments.
Beyond Early Childhood: Adolescents and Young People at Risk
The tragedy extends beyond early childhood, with an estimated 2.1 million individuals aged 5 to 24 also succumbing in 2024. Causes of death among adolescents show alarming gender-based patterns:
- Girls (15-19): Self-harm has emerged as the leading cause of death.
- Boys (15-19): Road traffic injuries remain the primary cause.
An Urgent Call to Action: Investing in Child Survival
Global health experts are sounding the alarm, warning that shifting development financing trends are placing critical maternal and child health programs under severe strain. Sustained investment in primary healthcare, robust data systems, and essential services is paramount to not only maintain but accelerate progress.
UNICEF Executive Director Catherine Russell emphasized the moral imperative: “No child should die from diseases that we know how to prevent. But we see worrying signs that progress in child survival is slowing, and at a time when we’re seeing further global budget cuts.”
WHO Director-General Tedros Adhanom Ghebreyesus echoed this urgency: “The world has made remarkable progress in saving children’s lives, but many still die from preventable causes. Children living amid conflict and crisis are nearly three times more likely to die before their fifth birthday. We must protect essential health and nutrition services and reach the most vulnerable families so every child has the chance not only to survive, but to thrive.”
Monique Vledder, World Bank Group Director for Health, described the findings as "a collective call to speed up implementation of the proven, scalable solutions we know are within reach," highlighting the institution’s commitment to expanding quality primary healthcare access.
United Nations Under-Secretary-General for Economic and Social Affairs, Li Junhua, cautioned that many countries are off track, stating, "We know how to prevent these deaths. What is needed now is renewed political commitment, sustained investment in primary health care, and stronger data systems to ensure no child is left behind."
Health researcher Li Liu reinforced that countless child deaths are entirely avoidable through cost-effective interventions, including:
- Widespread immunization programs.
- Improved nutrition initiatives.
- High-quality maternal and newborn care.
The report powerfully concludes that scaling up these proven, low-cost interventions—such as vaccines, treatment for malnutrition, and skilled care at birth—could dramatically reduce child mortality. Crucially, every dollar invested in child survival has the potential to generate up to twenty dollars in social and economic returns, underscoring the urgent need for governments and global partners to prioritize child health immediately.
