Measles Cases Surge: Global Immunization Gaps Widening
28 Nov
Summary
- Measles cases soared to 11 million in 2024 globally.
- Despite a 88% drop in deaths since 2000, cases are rising.
- Canada lost measles elimination status due to coverage gaps.
The World Health Organization reports a significant rise in measles cases globally, reaching an estimated 11 million in 2024. This marks an increase of nearly 800,000 cases since 2019. Despite dramatic reductions in measles-related deaths—down 88% since 2000—the surge in infections signals worrying gaps in routine immunization programs worldwide. Experts warn that even small declines in vaccine coverage can trigger widespread outbreaks.
Children remain the most vulnerable, with most measles deaths occurring in those under five, particularly in low-income and conflict-affected regions. While a highly effective vaccine exists, maintaining high coverage rates is crucial. Canada, for instance, recently lost its measles elimination status after failing to sustain the required 95% vaccination coverage, which allowed for sustained transmission.
Public health officials emphasize the need for better communication, trust-building, and combating misinformation to address these growing immunity gaps. Concerns are also mounting over potential further outbreaks in 2026 due to funding cuts affecting global laboratory networks and immunization programs.
