Statistics show Enfield has had 95 cases of measles

In Enfield, north London, 95 cases have been recorded, making it the worst-affected area in the capital.

Early indications suggest the outbreak may be stabilising in Enfield, but transmission remains a problem in surrounding boroughs.

Dr Tania Misra, consultant in health protection at the UK Health Security Agency (UKHSA), said: "The latest published data shows that Enfield continues to report the highest number of measles cases in London, with 95 cases recorded so far.

"We are also seeing cases in neighbouring boroughs, including 20 cases in Haringey and 18 cases in Islington.

"While there are early signs of stabilisation in Enfield, measles remains in circulation across North London.

"We continue to monitor the situation closely and work with local NHS and council partners as patterns change."

The apparent stabilisation in Enfield follows targeted public health action, including an intensified vaccination campaign.

More than 100,000 households in affected areas of Enfield and Haringey received NHS leaflets this week, advising residents of measles symptoms and encouraging immunisation.

The North Central London Integrated Care Board (ICB) reported a significant rise in MMR (measles, mumps, and rubella) vaccinations.

Dr Jo Sauvage, chief medical officer of North Central London ICB, said: "Across North Central London last year, an average of around 2,000 first and second dose MMR vaccinations were delivered each month.

"In February 2026, we saw around 3,600 MMR vaccinations delivered – that’s a sizable increase – in response to the outbreak, the expanded vaccination offer and the fact that local people have come forward.

"While it is difficult to make direct comparisons due to changes in eligibility, population size and seasonal factors, it’s clear that vaccination activity has increased markedly."

She said primary care teams had responded rapidly by making more than 800 additional vaccination appointments available in the area, contacting families, and setting up extra clinics.

The NHS is also funding Vaccination UK catch-up clinics for school-aged children.

More than 180 appointments have been offered in Enfield and Haringey since the end of January.

Despite the efforts, concerns remain about public understanding of the risks.

Dr Sauvage said: "Measles is not a mild illness.

"It can be very serious, particularly for young children and vulnerable people and we continue to see people who are very seriously unwell as a result.

"Vaccination remains the most effective way to protect people and reduce further spread."

Dudu Sher-Arami, director of public health for Enfield, praised the response from the community so far but warned that continued vigilance is needed.

Ms Sher-Arami said: "We have seen strong support from Enfield residents, community organisations and schools, with many families coming forward to check their vaccination status and take up the offer of the MMR vaccine.

"That response from the community has been really encouraging.

"However, measles cases remain higher than usual and we encourage everyone who has not taken action to check your families vaccination record."

Anyone who thinks they or their child may have measles should seek medical advice and avoid contact with others where possible.
