Reveals challenges to regain measles elimination status in Spain, highlighting needed interventions.
In January 2026, 2 days after the World Health Organization (WHO) Regional Verification Commission (RVC) for the European Region declared the re-establishment of endemic measles transmission in Spain, an outbreak linked to an office building, occurred in the city of Alicante, with 34 cases (median age: 44 years; interquartile range (IQR): 43–47) including 23 women and 11 men. Key factors shaping this outbreak underscore challenges and possible ways to regain transmission control, which might have relevance for re-achieving elimination status in Spain.
