Britain and several European countries have been stripped of their measles elimination status following a sharp rise in infections across the region, according to the World Health Organization. Alongside the UK, Spain, Austria, Armenia, Azerbaijan and Uzbekistan were also removed from the list of countries considered measles free, a development that health officials say reflects weakening vaccination coverage rather than the reemergence of a new threat.
The WHO said the loss of status was driven by sustained local transmission of the virus, which is one of the most contagious human diseases. Measles spreads rapidly in communities where immunization levels fall, often resurfacing first when routine vaccination programs are disrupted or public trust declines. Although preventable through vaccination, the illness can cause high fever, rashes, pneumonia, brain inflammation, and, in severe cases, death.
Public health experts across Europe have been warning that growing skepticism toward vaccines since the COVID-19 pandemic is fueling outbreaks of diseases that were previously under control. The WHO said the change in Britain’s classification is part of a wider regional challenge, noting that countries such as France and Romania are already experiencing regular measles transmission.

Elimination status is assessed by independent WHO committees that review national case data. To qualify, a country must record no locally transmitted cases of the same measles strain for at least 12 consecutive months. The decision affecting the European countries was reached in September based on 2024 surveillance figures, although the announcement was delayed until all governments involved formally signed off.
Vaccination coverage remains the decisive factor. The WHO estimates that more than 95 per cent of a population must be fully immunized to prevent sustained outbreaks. In the UK, that threshold is far from being met. Official figures show that only 84.4 per cent of children received both recommended doses of the measles, mumps and rubella vaccine in 2024. During the same year, England recorded 2,911 confirmed measles cases, the highest total in more than a decade.
Britain’s status has fluctuated before. It first achieved measles elimination in 2016, lost it two years later, and regained it in 2021, highlighting how quickly progress can be reversed when immunization rates slip.
Reacting to the announcement, the UK Health Security Agency renewed calls for parents to ensure their children are vaccinated, stressing that high uptake is the only reliable way to protect individuals and prevent further spread. The WHO echoed that message, urging European governments to prioritize outreach to under-vaccinated communities to stop measles from gaining a deeper foothold.
