Compared to 2024, when 127,412 cases were recorded, in 2025 the region registered 33,998 cases of measles, representing a decrease of nearly 75%. This reduction is linked to the implementation of special measures and a decrease in the number of people susceptible to the infection following serious outbreaks in areas with low vaccination rates.
The WHO Regional Director for Europe, Hans Kluge, noted that over the past three years, more than 200,000 people in the region have contracted measles. Despite positive trends, the figures for 2025 still exceed the levels of most years since 2000. In some countries, the number of cases was higher than in 2024, and measles cases continue to be recorded in 2026. WHO emphasizes that many of these cases could have been prevented through more active immunization and adequate outbreak response measures. Regina de Dominicis, UNICEF Regional Director for Europe and Central Asia, highlighted that the reasons for the increasing spread of measles remain relevant and require systemic solutions. She added that access to vaccination for all children must be guaranteed, and it is also necessary to combat the spread of misinformation about vaccination.
According to data from 2024, the European Regional Verification Commission for Measles and Rubella Elimination reported an increase in the number of countries with endemic measles transmission to 19, while the previous year there were only 12.
To prevent and contain the infection, UNICEF and WHO, together with the governments of the countries in the region and partners, are implementing comprehensive measures. These measures include engaging with local communities, training healthcare workers, strengthening immunization programs and epidemiological surveillance systems, as well as conducting catch-up vaccination campaigns.
Measles remains one of the most contagious viruses, capable of infecting up to 18 unvaccinated people from one infected individual, making it approximately 12 times more contagious than influenza. The disease can lead to hospitalizations, fatalities, and serious long-term complications. Additionally, measles can temporarily weaken immune memory, increasing vulnerability to other infections.
Two doses of the measles vaccine provide up to 97% lifelong protection. To achieve herd immunity, at least 95% of the population must be vaccinated, which will protect infants who are not yet of vaccination age, as well as individuals with medical contraindications.
