Measles
Last updated on Thursday, 19 December 2024 at 09:30am
Measles is a viral infectious disease. This page provides information about measles cases in England.
Cases are confirmed through either local or reference laboratory testing.
Numbers shown here are provisional and subject to change as:
more suspected cases undergo confirmatory testing
some locally tested cases are discarded after obtaining further epidemiological information or undergoing confirmatory testing at the reference laboratory
We update measles data every month on a Thursday at 9.30am. The next update will be on 16 January.
Since 1 January 2024, there have been 2,836 laboratory confirmed measles cases reported in England, an increase of 129 cases since the last report on 21 November 2024.
46% (1,295 of 2,836) of these cases have been in London, 20% (562 of 2,836) in the West Midlands, and 9% (244 of 2,836) in the East of England. 136 upper tier local authorities (UTLAs) have reported at least one confirmed case with symptom onset since January 2024, with the highest numbers reported in Birmingham (364 of 2,836, 13%), Lambeth (178 of 2,836, 6%) and Wandsworth (151 of 2,836, 5%).
