The UK reported 736 measles cases in the year to 7 November. The 30 days to 8 October 2026 had 19. No counts have been reported for 9 October to 7 November. Missing reports do not mean zero cases.

What the source says

These figures come from official surveillance reports. They count reports, not people. They are not an incidence rate, the rate of new cases in a population. They do not cover the whole population. The reporting periods do not match these dates exactly. Some reports are incomplete or still in progress. Some run past the window. Some reports do not say which date they use: symptom onset, notification, or confirmation.

Caveats

• No counts have been reported for 9 October to 7 November. Missing reports do not mean zero cases.

Retained reporting context

Sources and limitations

• Research: Measles, mumps and rubella: lab-confirmed cases in England 2026 (UKHSA · 2026-11-07)

• Window. Each quantity keeps its recorded source-selection dates and coverage notes. Dated batches and weekly or genomic observations retain their separate measures. Publication or capture dates do not establish case onset, equal cohorts or period completeness.
• Denominator. The retained counts do not establish complete populations, equal reporting cohorts or incidence rates. Source period bounds and definitions can differ.
• Case definition. Case definitions are set nationally and change over time. Counts for the same disease in different countries may not be counting the same thing.
• Revisions. Agencies restate figures. Values here are as reported at the time of publication; see the update history below.

ENCLAI counts reflect verified records available from reporting sources for the stated window. They are not estimates of total incidence and should not be interpreted as medical advice. Full methodology: the dataset.
