England measles epidemiology 2025
This report describes measles epidemiology in England from 1 January 2025.
Situational update
In 2024 there were 2,911 laboratory confirmed measles cases in England, the highest number of cases recorded annually, since 2012. Data for 2023 and 2024 and historical data are available.
Since 1 January 2025, there have been 674 laboratory confirmed measles cases reported in England, an increase of 145 cases since the last report on 3 July 2025 (Figures 1 and 2). Measles activity has increased steadily since April 2025 and the UK Health Security Agency (UKHSA) is overseeing the public health risk assessment and response.
Summary
The number of laboratory confirmed measles cases by month of symptom onset in 2025 to date are:
- January: 88
- February: 68
- March: 68
- April: 108
- May: 130
- June: 125
- July: 87
The provides tabular data on the total number of cases by week of onset in 2025.
The majority (467 of 674, 69%) of these cases were in children aged 10 years and under, and 25% (170 of 674) were in young people and adults aged 15 years and over (Table 1). 48% (322 of 674) of these cases have been in London, 16% (111 of 674) in the North West, and 10% (65 of 674) in the East of England. 90 upper tier local authorities (UTLAs) have reported at least one confirmed case with symptom onset since January 2025, with the highest numbers reported in Hackney (79 of 674, 12%), Bristol (47 of 674, 7%) and Salford (35 of 674, 5%) (Table 2a).
The vaccination status of all confirmed cases is published quarterly in the related health protection reports.
In 2025, one acute measles-related death occurred in a child who was known to have other medical conditions. Information on historical measles-related deaths is available on the notifications and deaths webpage.
Recent activity
There have been 96 laboratory confirmed measles cases with symptom onset date in the 4 weeks since 30 June 2025. Data reporting lags have the greatest impact on the most recent 4 weeks and therefore the reported figures are likely to underestimate activity.
Around two thirds (64%, 61 of 96) of these cases were in London and another third (34%, 33 of 96) in the North West. 26 UTLAs have reported at least one confirmed case with symptom onset since 30 June 2025, with the highest number of cases reported in Hackney (n=22) (Table 2b).

Figure 2. Laboratory confirmed cases of measles by week of onset of rash or symptoms reported, London and England: 1 January 2025 to 28 July 2025
Note 1: Cases confirmed through either local or reference laboratory testing.
Note 2: Data are provisional and subject to change as:
- more suspected cases undergo confirmatory testing
- some locally tested cases are discarded after confirmatory testing at the reference laboratory
The data reporting lag has had the greatest impact on the most recent 4 weeks and therefore the reported figures are likely to underestimate activity. For this reason, these data points are represented by dotted lines.
