London is at risk of a major resurgence of measles, health authorities warned on Friday, with modelling estimating tens of thousands of potential cases.
The UK Health Security Agency (UKHSA) said that a measles outbreak of between 40,000 and 160,000 cases could occur in the capital due to low vaccination coverage.
Measles is an infection that spreads very easily and can cause serious health problems. It usually starts with cold-like symptoms, followed by a rash a few days later.
Data published by the UKHSA showed that 128 cases of measles were recorded between January 1 and June 30 this year, compared to 54 cases in the whole of 2022.
Two-thirds of the cases were detected in London.
The UKHSA said the risk of an outbreak in the capital was “primarily due to low vaccination rates over several years”, particularly in some areas and groups where coverage of the first MMR dose at 2 years of age is as low as 69.5 per cent.
Their assessment also concluded that there is a high risk of cases linked to overseas travel leading to outbreaks in specific population groups such as young people and under-vaccinated communities.
Dr Vanessa Saliba, UKHSA Consultant Epidemiologist said: “Measles can be a serious infection that can lead to complications especially in young children and those with weakened immune systems. Due to longstanding sub-optimal vaccine uptake there is now a very real risk of seeing big outbreaks in London.
Dr Saliba said it was vital people get vaccinated with 2 doses of the MMR vaccine, which is free on the NHS whatever your age.
“Parents can check their children’s red book to see if they are up to date or if you’re not sure anyone can call their GP practice. It’s important everyone is fully vaccinated before travelling overseas this summer.”
“Nobody wants to see their child or loved ones sick with measles, or put others who are more vulnerable, like babies, at risk. I urge those who have missed their MMR vaccines to catch-up now.”
Jane Clegg, Regional Chief Nurse for the NHS in London said: “Measles can easily spread between unvaccinated people and can be serious, but it is preventable, which is why we continue to encourage Londoners to take up the vaccine – with GPs calling over 10,000 parents of unvaccinated children, and hundreds booking appointments to get vaccinated as a result.
“Cases of measles in the capital remain low but it’s really important that people check that they, and their children, are up to date with their jabs and protected against MMR – and if you have any questions or concerns, please get in touch with your GP practice or local pharmacist for advice. Now’s the time to act to protect yourself and loved ones from measles.”
