Answered by Ashley Dalton
The UK Health Security Agency (UKHSA) monitors trends in measles epidemiology and publishes a monthly report of laboratory confirmed cases of measles by age, region, and upper-tier local authority, available at the following link:
https://www.gov.uk/government/publications/measles-epidemiology-2023
The UKHSA also publishes a quarterly report of laboratory confirmed cases of measles by age, region, vaccination status, and imported vs community acquired cases, available at the following link:
Between 1 January and 10 April 2025, there have been 213 laboratory confirmed measles cases reported in England. The number of laboratory confirmed measles cases by month of symptom onset in 2025 to date are: 89 in January; 67 in February; 54 in March; and three so far in April.
The majority, 128 of 213, or 60%, of these cases were in children aged 10 years old and under, and 34%, or 72 of 213, were in young people and adults aged 15 years old and over. 24%, or 52, of these cases have been in London, 21%, or 44 cases, in the South West, and 17%, or 37 cases, in Yorkshire and Humber. 57 out of the 152 upper-tier local authorities have reported at least one confirmed case with symptom onset since January 2025, with the highest numbers reported in Bristol, at 34 of 213, or 16%, Leeds, at 29 of 213, or 14%, and Hertfordshire at 13 of 213, or 6%.
Data on measles cases by ethnicity is monitored but is not routinely published.
