In 2025, the region recorded 33,998 cases of measles, which is 75% less than in 2024, when 127,412 cases were reported. This decrease is attributed to the implementation of specific measures and a reduction in the number of people susceptible to the infection following major outbreaks in areas with low vaccination coverage.
The WHO Regional Director for Europe, Hans Kluge, noted that over the past three years, more than 200,000 people have contracted measles. Despite positive changes, the incidence rate in 2025 remains higher than in most years since 2000. In some countries, the number of cases even increased compared to 2024, and measles cases continue to be reported in 2026. According to WHO, many of these cases could have been prevented through broader coverage of routine immunization and timely outbreak response actions. Regina de Dominicis, UNICEF Regional Director for Europe and Central Asia, emphasized that the reasons for the rise in measles incidence remain relevant and require a comprehensive approach. She highlighted the need to ensure access to vaccination for all children and to combat misinformation about vaccines.
According to data from 2024, the European Regional Verification Commission for Measles and Rubella Elimination reported an increase in the number of countries where endemic measles transmission persists or has been newly reported — rising to 19, compared to 12 the previous year.
UNICEF and WHO, in collaboration with the governments of the region's countries and with the support of partners, are implementing programs to prevent and control infections. These measures include engaging with local communities, training healthcare workers, strengthening immunization programs and epidemiological monitoring systems, as well as catch-up vaccination campaigns.
Measles remains one of the most contagious viruses: one infected person can infect up to 18 unvaccinated individuals, making this disease approximately 12 times more contagious than influenza. Measles can lead to hospitalization, fatalities, and serious long-term complications. Additionally, this virus temporarily weakens the body's immune memory, increasing health risks from 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 immunized, which helps protect infants who are not yet of vaccination age and individuals with medical contraindications.
