South West tops the country for region with most measles cases in 2025 as UKHSA encourages further MMR vaccine uptake

The UK Health Security Agency (UKHSA) South West is urging parents to check that their children are up to date with their MMR vaccinations following confirmation of 30 new cases of measles in the region in the four weeks from 16 December 2024 to 13 January 2025.

• 30 new cases of measles within the South West in the four weeks from 16 December 2024 to 13 January 2025
• The South West has accounted for the highest proportion of measles cases in the country (46%) since 16 December 2024.
• 115 laboratory confirmed measles cases in the South West since 1 January 2024 (up until 13 January 2025) – https://www.gov.uk/government/publications/measles-epidemiology-2023/confirmed-cases-of-measles-in-england-by-month-age-region-and-upper-tier-local-authority-2024
• MMR vaccination rate for 2 doses across the South West is lower than 90% - Even a small drop in vaccine uptake below the WHO 95% target can lead to outbreaks.

The UK Health Security Agency (UKHSA) South West is urging parents to check that their children are up to date with their MMR vaccinations following confirmation of 30 new cases of measles in the region in the four weeks from 16 December 2024 to 13 January 2025. The South West has accounted for the highest proportion of measles cases in the country (46%) since 16 December 2024.

Bristol has also seen the most cases in the region since 1 January 2024, with 57 cases, followed by Gloucestershire (23) and Somerset (11). The UKHSA South West team is working with local authority and NHS partners to manage the response to these cases.

While measles cases have been declining overall across the country in recent months, the South West has seen a rise in cases. Most cases have been seen in children and young people, particularly in unvaccinated individuals.

Vaccination is a safe and effective way to stop the spread of measles and protect those most vulnerable to infection. Two doses of the MMR vaccines offers the best and safest protection against measles.

Dr Alasdair Wood, Consultant in Health Protection for UKHSA South West said:  

“Measles has been circulating across the country over the last 12 months, with 115 laboratory confirmed measles cases in the South West since 1 January 2024, the majority of which were confirmed in November and December of 2024, and this more rapid rise in cases within the region is concerning.

“Measles is highly infectious, and it can cause serious disease or even death in some rare cases. If you suspect that you or a family member has measles, it is important that you seek medical advice and stay away from schools, large gatherings and workplaces while infectious. People are infectious from four full days before and until four full days after the rash appears.

“Those at the highest risk of severe infection include pregnant women, children under one year old and immunocompromised individuals. We all have a responsibility to help protect these groups by getting vaccinated and reducing the spread of the infection.

“It’s never too late to have the vaccine, so if you’ve not received two doses of the vaccine in the past – or you’re unsure – speak to your GP. There’s no harm in receiving an additional dose where there is any uncertainty.

“The MMR vaccine is safe and by far the most effective way to protect yourself and those around you.

“We are asking everyone to remain alert to the symptoms of measles, which can include cold-like symptoms, sore red eyes, a high temperature or a red-brown blotchy rash.

“If you experience these symptoms, seek medical attention, but please ensure that you phone ahead before visiting a healthcare setting, such as your GP surgery, so that arrangements can be made to prevent others from being infected.”
