Measles Mortality: Global Deaths, Risks & Prevention

Measles is a highly contagious viral illness that can cause severe complications—pneumonia, encephalitis, blindness—and death. Despite an effective vaccine, the World Health Organization (WHO) estimated 140,000 measles deaths globally in 2018, the highest toll in over a decade. The burden falls disproportionately on low‑ and middle‑income countries and children under five.

Key Facts

• Transmission: airborne respiratory droplets; one case can infect 12–18 susceptible contacts.
• Complications: otitis media, diarrhea, pneumonia (leading cause of death), encephalitis (1/1,000 cases), subacute sclerosing panencephalitis (SSPE, rare fatal late sequela).
• Risk factors: malnutrition, vitamin A deficiency, immunodeficiency, lack of vaccination.

Prevention

The measles‑containing vaccine (MCV) is safe, inexpensive, and highly effective. WHO recommends:

• Two doses: first at 9–12 months, second at 15–18 months (or per national schedule).
• ≥95% coverage with both doses to achieve herd immunity and prevent outbreaks.
• Vitamin A supplementation for infected children reduces mortality by ~50%.

Global Efforts

The Measles & Rubella Initiative and Gavi, the Vaccine Alliance, support immunization campaigns, surveillance, and outbreak response. Sustained political commitment and funding are essential to eliminate measles.
