Major Measles Outbreak Hits London
A leaked UK Health Security Agency (UKHSA) report reveals a growing measles outbreak in London, with more than 300 suspected cases recorded since the start of 2026. The internal document highlights 34 confirmed infections linked to a single school in Enfield between 20 January and 7 February.
Rising Cases Amid Falling Vaccination Rates
Public health officials are concerned as vaccination rates decline, particularly in northeast London. Recent data shows 104 reported cases, with 71 confirmed across Enfield and Haringey. The UK also recently lost its measles elimination status, and a child tragically died from the disease in Liverpool last year.
Age and Area Distribution of Cases
The internal report indicates that most measles infections are among young children. Between 27 January and 24 February, 37 cases were confirmed in children aged 1–4, and 22 cases in those aged 5–11. Notably, 42 of the affected children live in London’s most deprived areas, highlighting the connection between socio-economic factors and vaccine coverage.
Vaccination Gaps Drive Spread
According to the report, 78% of children aged 1–4 and 90% of children aged 5–11 involved in the outbreak were unvaccinated. UK children are offered the first MMRV dose at 12 months and a second at 18 months, but uptake has reached record lows in certain boroughs, including Hackney and Enfield, where less than two-thirds of children received both doses in 2024/25.
Expert Warnings on Measles Risks
Dr. Yimmy Chow, UKHSA London deputy director, stressed the seriousness of measles, highlighting its potential to cause pneumonia, meningitis, blindness, seizures, and death. He emphasized that unvaccinated children remain highly vulnerable, warning parents against complacency.
Call to Action for Vaccination
Local healthcare leaders urge families to vaccinate their children to protect both individual and public health. Dr Josephine Sauvage, CMO of the North Central London Integrated Care Board, praised NHS staff and GPs for proactive outreach, including out-of-hours clinics, to ensure children receive timely MMRV vaccinations.
