🟢 Strong Evidence
Two children have died from measles in England this year as confirmed cases surge to 736 in the first half of 2026, marking a concerning escalation in preventable disease deaths. The UK Health Security Agency (UKHSA) reported that May alone recorded 182 confirmed cases, the highest monthly figure this year, with most cases occurring in unvaccinated children aged 10 and under.
Key takeaways
- 736 measles cases confirmed in England by June 8, 2026, compared to 959 for all of 2025
- Two children have died from measles complications in 2026
- London, East of England, and West Midlands are worst affected regions
- Majority of cases occur in unvaccinated children aged 10 years and under
Fatal Cases Mark Concerning Escalation
The UK Health Security Agency confirmed that one child died from acute measles, while another death occurred in a child with underlying conditions where measles was a contributing factor. These represent the first measles-related pediatric deaths in England since the disease was declared eliminated in 2017.
“Measles activity increased earlier this year, mainly due to outbreaks in London and the West Midlands, with the majority of cases in unvaccinated children aged 10 years and under,” UKHSA stated in its latest epidemiological update. The agency’s surveillance data shows cases have more than doubled compared to the same period last year.
Geographic Concentration in Three Regions
London has emerged as the primary hotspot, accounting for the largest proportion of cases over the past four weeks. The East of England and West Midlands follow as the second and third most affected regions, according to UKHSA surveillance reports.
The current outbreak trajectory suggests England could exceed 1,400 cases by year-end if transmission rates continue at current levels. This would represent the highest annual case count since measles elimination status was achieved. For broader context on vaccine-preventable diseases, see our clinical updates section.
Vaccination Gaps Drive Outbreak Spread
The concentration of cases in unvaccinated children under 10 highlights persistent immunization gaps in England’s measles-mumps-rubella (MMR) vaccination program. World Health Organization data indicate that measles requires 95% population immunity to prevent outbreaks.
UKHSA epidemiologists note that declining vaccination rates during the COVID-19 pandemic created susceptible cohorts, particularly among children who missed routine immunizations between 2020-2022. Recovery efforts have been complicated by persistent vaccine hesitancy in certain communities.

What this means
Frequently asked questions
How serious is measles in children?
Measles can cause severe complications including pneumonia, encephalitis, and death, particularly in children under 5 years. The case fatality rate ranges from 0.1-0.3% in developed countries with adequate healthcare.
Why are unvaccinated children most affected?
The MMR vaccine is highly effective, preventing 97% of measles cases after two doses. Unvaccinated children have no immune protection against this highly contagious virus that spreads through respiratory droplets.
What should parents do if they suspect measles?
Contact healthcare providers immediately before visiting clinical facilities to prevent spread. Children with suspected measles should be isolated and kept away from school or childcare until cleared by medical professionals.
The current outbreak represents a critical test of England’s measles elimination efforts, requiring coordinated public health response to prevent further pediatric deaths. UKHSA continues enhanced surveillance while health authorities work to identify and vaccinate susceptible populations in affected regions.
