Public health officials have updated England’s measles surveillance information, adding confirmed case data for 2026 and continuing a series of detailed monthly breakdowns used to track the infection across the country.
The latest update covers confirmed measles cases in England by month, age group, region and upper tier local authority. Upper tier local authorities include county councils, unitary authorities, metropolitan districts and London boroughs, making the data useful for understanding where cases are being recorded at a local level.
The update is part of the continuing publication of measles epidemiology data for England from 2023 onwards. Epidemiology means the study of how a disease is spreading, who is affected and where cases are occurring. For measles, this information helps health protection teams, local NHS services, councils, schools and nurseries understand patterns of infection and respond where needed.
The published records have been updated several times since 2023, with monthly figures added and revised datasets produced for 2024, 2025 and now 2026. Earlier reporting linked to the National Measles Standard Incident, which began in October 2023, has since been replaced by annual datasets setting out confirmed cases by time, age and geography.
The update does not, by itself, announce new restrictions or a change to routine NHS services. Its main practical importance is that it gives public health teams a clearer view of where confirmed measles cases have been reported and which age groups are most affected. That can support local vaccination reminders, contact tracing and advice to settings where the infection could spread more easily.
Measles is a highly infectious viral illness. It can spread through coughs and sneezes and can be passed on before a person knows they are infected. For many people it causes a fever, cough, runny nose, sore eyes and a blotchy rash, but it can lead to serious complications, particularly for babies, pregnant women and people with weakened immune systems.
The main protection against measles is the MMR vaccine, which protects against measles, mumps and rubella. The NHS routine childhood programme offers two doses, but public health teams have repeatedly warned that lower vaccine uptake leaves gaps in community protection. Where uptake is lower, measles can spread more easily after an imported case or local exposure.
For households, the data matters because measles control often depends on rapid local action. If cases are confirmed in a council area, local health teams may contact close contacts, advise schools or nurseries, and encourage people who are not fully vaccinated to check their records. Parents and carers may also see local reminders from GP practices, NHS services or councils if cases are identified nearby.
Schools, childcare settings and health services can also be affected. Measles can lead to exclusion advice for people who may be infectious, additional infection control measures and follow up with vulnerable contacts. These steps are designed to reduce spread and protect those who cannot be vaccinated or may be at greater risk from complications.
Confirmed case data is different from general reports of suspected illness. A confirmed case is one recorded through the public health surveillance system after testing or formal assessment. Because reporting can be updated as investigations continue, figures may be revised over time. This is one reason the datasets are refreshed regularly rather than treated as final immediately after publication.
The regional and local authority breakdowns are particularly important because national totals can hide local variation. A small number of cases in one area may require a targeted response if they are linked to a school, nursery, healthcare setting or community with lower vaccination coverage. In another area, the same national period may show little or no activity.
People who are unsure whether they or their children have had both MMR doses can check their child health record, use the NHS App where available, or contact their GP practice. Anyone with symptoms that may be measles is generally advised by the NHS to seek advice before attending a GP surgery, urgent treatment centre or hospital, so services can reduce the risk of passing the infection to others.
The current position is that England’s measles surveillance for 2026 is now being published alongside updated records for previous years. The data will continue to help public health teams monitor confirmed cases by month, age and local area, while households and local services use NHS and public health advice to reduce the risk of further spread.
