According to the UK Health Security Agency (UKHSA), 100 additional measles cases were reported in England in the past month, bringing the total confirmed cases to 420 in 2025.
Four out of 10 cases have been reported from London (162), while 14% (58 of 420) in the South West, and 14% (57 of 420) in East of England were reported.
The majority (276 of 420, 66%) of these cases were in children aged 10 years and under, and 29% (121 of 420) were in young people and adults aged 15 years and over.
In 2024 there were 2,911 laboratory confirmed measles cases in England, the highest number of cases recorded annually, since 2012. This was initially driven by an outbreak in Birmingham but was soon overtaken by a large outbreak in London, with small clusters in other regions. Case counts followed a downward trajectory from mid-July with small, localised outbreaks continuing in some regions.
