According to an analysis by WHO and the United Nations Children’s Fund (UNICEF), 127 350 measles cases were reported in the European Region for 2024, double the number of cases reported for 2023 and the highest number since 1997.

Children under 5 accounted for more than 40% of reported cases in the Region – comprising 53 countries in Europe and central Asia. More than half of the reported cases required hospitalization. A total of 38 deaths have been reported, based on preliminary data received as of 6 March 2025.

Measles cases in the Region have generally been declining since 1997, when some 216 000 were reported, reaching a low of 4440 cases in 2016. However, a resurgence was seen in 2018 and 2019 – with 89 000 and 106 000 cases reported for the 2 years respectively. Following a backsliding in immunization coverage during the COVID-19 pandemic, cases rose significantly again in 2023 and 2024. Vaccination rates in many countries are yet to return to pre-pandemic levels, increasing the risk of outbreaks.

“Measles is back, and it’s a wake-up call. Without high vaccination rates, there is no health security. As we shape our new regional health strategy for Europe and central Asia, we cannot afford to lose ground. Every country must step up efforts to reach under-vaccinated communities,” warned Dr Hans Henri P. Kluge, WHO Regional Director for Europe. “The measles virus never rests – and neither can we.”
