Médecins Sans Frontières (MSF) has raised concerns over worsening malnutrition, recurring disease outbreaks and persistent maternal health challenges in Nigeria, warning that weak healthcare access and deepening humanitarian pressures are leaving vulnerable communities at greater risk.

The humanitarian organisation disclosed this on Wednesday in Abuja during the launch of its 2025 Country Activity Report, which documents trends observed across its medical operations in several states.

According to the report, MSF in collaboration with health authorities, treated more than 440,000 children for malnutrition in 2025, the highest number recorded by the organisation in Nigeria in recent years.

The figure includes 353,989 children treated through outpatient nutrition programmes and 90,723 others admitted into inpatient stabilisation centres for severe acute malnutrition with complications.

MSF said the steady rise in admissions since 2022 reflects worsening living conditions in many parts of the country, particularly in conflict-affected communities where displacement, flooding, inflation and food insecurity continue to disrupt access to food and healthcare.
