England has recorded 235 measles cases in 2026, with the UK Health Security Agency confirming outbreaks concentrated in North London and Birmingham as health officials consider stronger measures
Measles cases have rocketed across England, with week-on-week data revealing a dramatic spike as a “stronger measures” warning has been issued. A staggering 235 cases of the highly infectious Victorian disease have been logged in 2026 up to March 9.
The UK Health Security Agency (UKHSA) has confirmed that measles activity has escalated since January 2026, predominantly fuelled by clusters in North London and Birmingham. Officials revealed that between January 1 and March 9 this year, 235 laboratory-confirmed measles cases were documented across England.
This represents a substantial jump in infections from the previous update on March 5, with 40 additional cases emerging within just seven days.

The condition, characterised by flu-like symptoms and a distinctive rash, was widespread throughout Britain during the mid-20th century, when almost half a million cases and over 1,000 fatalities were recorded each year. No severe measles-related deaths have been documented so far this year.
This year’s outbreak has predominantly affected younger demographics. The vast majority (71%) of cases occurred in primary school pupils aged 10 and under, whilst 23% were among teenagers and adults aged 15 and above, reports the Express.
Distinct regional clusters have also emerged. Around 62% of these cases were concentrated in London, affecting 146 individuals, with 22% occurring in the West Midlands. Merely 5% of cases were identified in the North West.
Nevertheless, the UKHSA highlighted that every region has recorded at least one confirmed case with symptoms beginning since January 2026. Examining the figures at local authority level, Enfield recorded the highest numbers with 80 cases, whilst Birmingham followed with 43, and Haringey reported 15.
The agency also observed that the statistics were “likely to underestimate activity”, owing to delays in data reporting.
February witnessed the peak number of measles cases, with 121 confirmed instances, compared to 105 in January. Throughout the nine reporting days in March, there had been nine confirmed measles cases.
The introduction of the MMRV or MMR vaccine from 1968 has preserved more lives than any other vaccination over the past 50 years. The NHS states it represents the most effective method of prevention.
Measles transmits extremely easily and typically begins with cold-like symptoms, followed by a rash several days later. Some individuals may also develop small spots inside their mouth.
A correspondence sent by Enfield Council to parents across the borough in January urged unvaccinated pupils who had close contact with measles cases to remain absent from school for 21 days, following national guidance.
Ahead of an emergency meeting convened by the London Assembly this week, health committee chair Emma Best suggested the policy should be implemented in other regions as well.
Ms Best told the Daily Mail: “Obviously no one wants to see children out of school, but there is a point where it becomes too dangerous for an unvaccinated child to be in that environment.
“If there is a significant risk where someone could die – which is a very real risk with measles – then we have to consider stronger measures. The converse of not doing that is far too risky.”
