Measles deaths dropped by 88% worldwide between 2000 and 2024, according to a new World Health Organisation (WHO) report released on 28 November 2025. The organisation said global immunisation campaigns saved nearly 59 million lives, showing the impact of widespread vaccination. However, measles infections increased to an estimated 11 million cases in 2024.
Rising Outbreaks
WHO warned that measles is resurging because vaccination coverage remains too low in many countries. In 2024, 59 nations recorded large or disruptive outbreaks, almost triple the number reported in 2021. Infections rose sharply in the Eastern Mediterranean, Europe, and South-East Asia, while the African Region showed a strong decline due to better immunisation rates.
Why It Matters
Measles is one of the most contagious viruses. Children under five remain the most at risk of death or severe complications, including blindness and brain damage. WHO said at least 95% coverage with two vaccine doses is needed to stop outbreaks, yet over 30 million children were under-protected in 2024.
Progress Toward Elimination
By late 2025, 96 countries had eliminated measles, including new progress in Africa and the Pacific. But several areas, including the Americas, lost elimination status again due to ongoing transmission. WHO urged governments to strengthen immunisation, improve surveillance, and close immunity gaps.
