Measles Cases Rise Across England as New Figures Highlight Hotspots and the Importance of Vaccination
England is facing renewed concern over measles after laboratory-confirmed cases recorded during 2026 passed the total reported for the whole of 2025.
Figures from the UK Health Security Agency show that 970 confirmed measles cases had been recorded in England by 20 August 2026. That compares with 960 laboratory-confirmed cases during the entirety of 2025. The latest figures are provisional and may be revised as further information becomes available.
The rise has prompted renewed calls for parents and carers to check whether children have received the recommended vaccinations before the new school year begins.
London remains a major area of concern
The distribution of cases is not even across England. According to figures reported from the latest UKHSA data, London accounts for more than half of the cases recorded so far this year.
Enfield has reported the highest number, with 111 cases, followed by Birmingham with 81 and Hertfordshire with 63. Other London boroughs, including Haringey and Islington, have also recorded significant numbers.
Overall, cases have been reported in 96 of England's 153 local authorities since the beginning of the year.
The concentration of infections in particular areas highlights how quickly measles can spread when vaccination coverage falls below the level needed to maintain strong community protection.
Children are particularly affected
Children make up a large proportion of the cases recorded in 2026. Around 61 percent of the 970 confirmed infections have been among children aged 10 and under.
Children aged one to four accounted for 263 cases, while 213 cases were reported among those aged five to 10.
This is particularly important as schools and nurseries bring large numbers of children together. Measles is highly infectious, meaning an infected person can transmit the virus to people who are not immune.
NHS England has also warned that measles cases are increasing and has encouraged families to make sure children have received both recommended doses of a measles-containing vaccine.
Why measles can be dangerous
Measles is sometimes dismissed as a routine childhood illness, but infection can lead to serious complications.
The illness commonly begins with cold-like symptoms, fever, tiredness and other flu-like symptoms. A characteristic rash usually develops later.
Although many people recover, some patients can develop complications affecting the lungs, brain or other parts of the body. Young children and people with certain medical conditions can be particularly vulnerable.
This is why preventing infection remains a central part of public health efforts.
The most effective protection is vaccination. The NHS states that after two doses of the MMR vaccine, around 99 percent of people are protected against measles and rubella.
The vaccination programme has changed
Parents may notice that the childhood vaccination schedule has changed in England during 2026.
The NHS now offers the combined MMRV vaccine, which protects against measles, mumps, rubella and chickenpox. For children covered by the new schedule, the vaccine is given in two doses, with timing depending on the child's date of birth. For children born on or after 1 January 2025, the routine schedule gives doses at 12 and 18 months.
Children who were born earlier may follow a different schedule, so parents should check their child's vaccination history with their GP surgery or NHS records.
The NHS also continues to offer catch-up vaccination for children and adults who missed earlier doses.
NHS England says parents do not need to wait for an invitation if their child has not received both recommended doses. Families can contact their GP surgery to arrange vaccination.
What caused vaccination coverage to fall?
The current situation has been linked to years of lower vaccination coverage in some communities.
One important historical factor was the controversy surrounding the MMR vaccine following the publication of a 1998 study that falsely suggested a connection between the vaccine and autism. The study was subsequently discredited and withdrawn, and extensive research has found no link between MMR vaccination and autism. The NHS explicitly states that there is no evidence that the MMR vaccine causes autism.
However, the damage to public confidence contributed to lower vaccination rates, leaving some communities with gaps in protection.
Public health authorities generally aim for very high vaccination coverage because measles spreads exceptionally easily. NHS England describes two doses of a measles-containing vaccine as the best way to prevent infection and transmission.
What parents can do now
The most practical step for families is to check vaccination records.
If a child has received only one dose, or if records are unclear, parents can contact their GP surgery for advice. NHS guidance says children who have missed vaccinations can still receive catch-up doses.
Adults who are unsure about their own vaccination history can also speak to their GP.
Parents should also learn the common signs of measles. These can include fever, cold-like symptoms, tiredness, sore or red eyes and a developing rash.
If measles is suspected, it is important to seek medical advice while avoiding unnecessary contact with other people because of the infection's high transmissibility. Families should follow NHS advice about contacting healthcare services.
The wider public health picture
The latest figures are a reminder that infectious diseases can return when immunity levels fall.
The fact that England has already recorded more laboratory-confirmed measles cases in 2026 than during the whole of 2025 does not mean every part of the country faces the same level of risk. Cases are concentrated in particular communities and local authorities.
It does, however, demonstrate why maintaining high vaccination coverage remains important.
The UKHSA measles dashboard provides the latest information on confirmed cases and explains that the figures are provisional and subject to change.
For families, the message is straightforward: check vaccination records, arrange any missed doses and seek reliable medical advice if you are concerned about symptoms or possible exposure.
Measles is preventable, and vaccination remains one of the most effective tools available for protecting children, families and vulnerable members of the wider community.
