Last updated on Thursday, 14 May 2026 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 every other week on Thursdays at 9.30am. On weeks with a bank holiday on Monday or Tuesday, the update will be on Friday at 9.30am. The next update will be on Friday 29 May.

Cases by week of symptom onset

Laboratory confirmed cases of measles by week of onset of rash or symptoms reported, London and England from 1 January 2024. The data reporting lag has greatest impact on the most recent 4 weeks. Reported figures for this period are likely to underestimate activity. These data points are within the "reporting delay" period on the chart. This chart is different to the measles "cases reported" chart on the landing page. Data affected by the reporting delay is not included in the chart on the landing page.
