The international medical organization Médecins Sans Frontières (MSF) has raised alarm over a severe measles outbreak in Yemen’s Dhamar governorate, warning that the situation poses a growing threat to vulnerable children amid a collapsing healthcare system.

Between April and July 2025, MSF treated over 1,400 measles cases, with 56% of patients under the age of five, according to a statement released on Monday. The organization reported a 219% increase in cases compared to the same period last year, underscoring the rapid spread of the disease in Houthi-controlled areas.

MSF teams are currently operating from an isolation ward at Al-Wahda Hospital in Ma'bar city, supported by three mobile clinics covering six districts. The organization cited low vaccination coverage, restricted access to medical services, and anti-vaccine rhetoric by Houthi leaders as key factors fueling the outbreak.

“The sharp rise in infections reflects the collapse of Yemen’s health infrastructure due to prolonged conflict and declining humanitarian funding,” said Desma Maina, MSF’s Country Director in Yemen. “Many families are unable to reach basic care, and children are paying the price.”

MSF called for an urgent public health response, including expanded immunization campaigns and improved access to treatment. The organization reaffirmed its commitment to supporting the most affected communities but stressed that coordinated efforts from all health actors are needed to prevent further deterioration.
