According to UN agencies, measles cases in Europe have doubled in just one year and are at their highest level since 1997.
The World Health Organization and the UN Children’s Fund announced this in a statement on Thursday.
“Measles is back, and it’s a wake-up call,” WHO regional director for the European region, Dr. Hans Kluge, said.
A total of 127,350 cases were reported in the region in 2024, double the number of cases reported for 2023 and the highest number since 1997, according to analysis by the UN agencies.
Among the most contagious viruses affecting people, measles can damage the immune system by “erasing” its memory of how to fight infections, leaving survivors vulnerable to other diseases.
“As well as hospitalization and death caused by complications including pneumonia, encephalitis, diarrhea, and dehydration, measles can also cause long-term, debilitating health complications such as blindness.”
According to the WHO, there were an estimated 107,500 measles deaths globally in 2023, mostly among unvaccinated or undervaccinated children under five.
“Measles remains a significant global threat,” the UN agencies said, pointing to the 359,521 cases reported for 2024 worldwide.
Current outbreaks and deaths had been reported worldwide, including in the Democratic Republic of the Congo, the United States, and countries in every other region.
Based on preliminary data received as of March 6, 2025, a total of 38 deaths had been reported for WHO’s European region, which comprised 53 countries in Europe and Central Asia.
The region accounted for one-third of all measles cases globally in 2024.
UN agencies pointed to a resurgence in 2018 and 2019, with 89,000 and 106,000 cases, respectively, after a period of decline since 1997, with 216,000 reported cases, that reached a low of 4,440 in 2016.
Following a backsliding in immunization coverage during the COVID-19 pandemic, cases rose significantly again in 2023 and 2024, the UN agencies said, adding that vaccination rates in many countries were yet to return to pre-pandemic levels, increasing the risk of outbreaks.
Transmission of the virus across borders and continents occurred regularly, and outbreaks of this highly infectious disease will occur wherever the virus finds pockets where vaccine levels are insufficient—particularly children, they cautioned.
Currently, children under five accounted for more than 40 percent of reported cases in the region, and more than half of all cases required hospitalization.
“Measles cases across Europe and Central Asia have soared over the past two years, pointing to gaps in immunization coverage,” Regina De Dominicis, UNICEF regional director for Europe and Central Asia, said.
In 2023 alone, 500,000 children across the region missed the first dose of the measles vaccine (MCV1) that should be given through routine immunization services.
“To protect children from this deadly and debilitating disease, we need urgent government action, including sustained investment in health care workers,” she said.
Kluge said “we can’t afford to lose ground” as the agency shapes its regional health strategy to tackle such serious issues.
“Without high vaccination rates, there is no health security.
“Every country must step up efforts to reach undervaccinated communities. The measles virus never rests and neither can we,” he said.
Indeed, vaccination is the best line of defense against the virus, the UN agencies insisted.
The latest analysis found that Romania reported the highest number of cases—30,692—in the region for 2024, followed by 28,147 in Kazakhstan.
At the same time, less than 80 percent of eligible children in Bosnia and Herzegovina, Montenegro, North Macedonia, and Romania were vaccinated with MCV1 in 2023.
In both Bosnia and Herzegovina and Montenegro, the coverage rate for MCV1 has remained below 70 percent and 50 percent, respectively, for the past five or more years.
That is far below the 95 percent coverage rate required to retain herd immunity, the UN agencies noted.
UNICEF and WHO are working with governments and health partners, including the European Union and the GAVI Alliance, to prevent and respond to measles outbreaks by engaging with communities.
Efforts included training healthcare workers, strengthening vaccine programs and disease surveillance systems, and initiating measles immunization catch-up campaigns.
“It is imperative that countries analyze the root causes of outbreaks, address weaknesses in their health systems, and strategically utilize epidemiological data to identify and close coverage gaps,” the UN agencies stated.
“Reaching hesitant parents and marginalized communities and tackling inequitable access to vaccines must be central to all efforts,” they added.
They also warned that countries without current measles outbreaks should be prepared, including through identifying and addressing gaps in immunity, building and sustaining public trust in vaccines, and maintaining strong health systems.
