England measles epidemiology 2026
This report describes measles epidemiology in England from 1 January 2026.
Situational update
In 2024 there were 2,911 laboratory confirmed measles cases in England, the highest number of cases recorded annually, since 2012. In 2025, there were a total of 959 laboratory-confirmed measles cases. Data for 2023 to 2025 and historical data are available.
Between 1 January 2026 and 27 April 2026, there have been 477 laboratory confirmed measles cases reported in England, an increase of 35 cases since the 20 April 2026 (Figures 1 and 2). Measles activity increased from January 2026, with the highest number of cases concentrated in North London and Birmingham (Table 1 and 2).
Summary
The number of laboratory confirmed measles cases by month of symptom onset in 2026 to date are:
- January: 106
- February: 142
- March: 140
- April: 89 (to date)
The UKHSA data dashboard provides tabular data on the total number of cases by week of onset in 2026.
The majority (317 of 477, 66%) of these cases were in children aged 10 years and under, and 28% (134 of 477) were in young people and adults aged 15 years and over (Table 1). 58% (277 of 477) of these cases have been in London, 23% (111 of 477) in the West Midlands, and 8% (36 of 477) in the North West. However, all regions have reported at least one confirmed case with symptom onset since January 2026. 63 upper tier local authorities (UTLAs) have reported at least one confirmed case with symptom onset since January 2026, with the highest numbers reported in Enfield (98 of 477, 21%), Birmingham (74 of 477, 16%) and Islington (44 of 477, 9%) (Table 2a).
The vaccination status of all confirmed cases is published quarterly in the related health protection reports.
No acute measles-related deaths have been reported to date in 2026. Information on historical measles-related deaths is available on the notifications and deaths webpage.
Recent activity
There have been 101 laboratory confirmed measles cases with symptom onset date in the 4 weeks since 30 March 2026. Data reporting lags have the greatest impact on the most recent 4 weeks and therefore the reported figures are likely to underestimate activity. London accounted for the highest proportion of these cases (66%, 67 of 101). 19% (19/101) of cases have been in the West Midlands, and 9% (9 of 101) in the North West. 26 UTLAs have reported at least one confirmed case with symptom onset since 30 March 2026, with the highest number of cases reported in Islington (n=19) and Haringey (n=11) (Table 2b).

Figure 2. Laboratory confirmed cases of measles by week of onset of rash or symptoms reported, London and England: 1 January 2026 to 27 April 2026 [notes 1 and 2]
Note 1: cases confirmed through either local or reference laboratory testing.
Note 2: data is 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.
