Criteria and Epidemiological EvidenceMeasles elimination status is not tied to the absence of all cases; imported infections do not in themselves negate elimination. In Spain, the WHO verification commission reviewed data from 2024 showing multiple confirmed measles cases and clusters across different regions. The UK’s loss of status was based on epidemiological reporting for 2024, when measles transmission was documented across the country after years of low incidence. Broader Regional ContextSpain and the UK are among six European countries whose measles elimination status has been removed recently. Looking ForwardThe WHO emphasises that loss of elimination status is not irreversible.
