The UK is currently facing a growing measles outbreak, with cases rising rapidly in recent weeks. Health authorities have declared a national incident in response to the worrying trend.

Measles Cases Reach Alarming Levels

According to the UK Health Security Agency (UKHSA), over 700 cases of measles have now been reported across England. This represents a significant increase compared to previous years – there were only 224 confirmed cases in all of 2023.

The outbreak appears to have started in the West Midlands, which has seen over 300 cases since the start of the year. However, authorities say measles is now spreading to other parts of the country at an alarming pace.

“We’re seeing cases in nearly all regions of England, signaling that this outbreak is becoming more generalized,” said Dr. Susan Hopkins, Chief Medical Advisor at UKHSA. “Urgent action is needed to get vaccination levels up and prevent further spread.”

Falling Vaccination Rates Blamed

Health officials attribute the outbreak largely to declining vaccination coverage. Over the past decade, uptake of the combined MMR (measles, mumps and rubella) vaccine has steadily dropped:

Year MMR Vaccine Uptake
2013 92.7%
2023 81.3%

This means almost 1 in 5 children are now starting school without the recommended 2 doses of MMR. That leaves large gaps in the population’s immune defenses against highly infectious diseases like measles.

“Measles is one of the most contagious diseases known to man – one case can easily trigger an outbreak if vaccination levels slip,” said Dr. Mary Ramsay, Head of Immunization at UKHSA. “Sadly, that is precisely the situation we are now dealing with.”

Most Cases in Unvaccinated Children

Authorities report that the majority of current cases – over 70% – are in unvaccinated children under 5 years old. However, a concerning number of cases are also appearing in older age groups.

“We’re seeing measles hit young adults who may have missed out on MMR shots in childhood,” said Dr. Hopkins. “This highlights how the choices of a small group not to vaccinate can put whole communities in danger.”

Among the worst-affected areas outside the West Midlands are London, where at least 20 schools have reported cases, as well as Yorkshire, the South East and East of England. Wales has also seen its highest number of cases in over a decade.

Calls for Urgent Action as Measles Spreads

In response to the widening outbreak, health leaders across the UK are urging parents to ensure children receive timely MMR vaccinations.

The UKHSA has asked local health teams to offer pop-up vaccination clinics and target communication at vulnerable communities. Schools and nurseries may also contact parents directly about booking appointments.

However, some experts argue bolder action is needed to reverse the slide in vaccine confidence driving falling immunization rates.

“We need a serious public debate around how to strengthen mandates, otherwise we risk seeing not only measles but other deadly diseases of childhood come surging back,” said Heidi Larson, Professor of Vaccine Confidence at the London School of Hygiene and Tropical Medicine.

What is Causing the Fall in Vaccine Uptake?

Research points to a complex mix of factors behind declining childhood vaccination rates – no single cause stands out.

In focus groups, parents commonly cite complacency around risks from vaccine-preventable illness as one reason. Others feel bombarded by contradictory messaging that fuels safety fears.

Some faith and cultural groups have specific concerns about ingredients in vaccines, while schedule constraints also play a role for certain demographics.

However, scientists argue much anti-vaccine rhetoric circulates misinformation amplified online rather than reflecting genuine issues. This risks undermining public health programs without basis.

“We have incredibly strong evidence that vaccines approved for use are safe and fears around side effects such as autism have been conclusively disproven,” said Professor Larson. “Shoring up access and combating false claims with clear communication are vital.”

What are the Risks If Measles Continues to Spread?

If transmission remains unchecked, experts warn we could see numbers spiral to levels not found in decades.

The UK eliminated endemic measles transmission in 2016 after achieving consistent immunization coverage over 90% for many years. However, that status is now in jeopardy amid faltering vaccination rates.

Previously measles led to several deaths and over 1000 hospital admissions per year in England alone. Serious complications can include blindness, pneumonia, brain infections and severe vomiting/diarrhea leading to dehydration.

Pregnant women risk early labor or losing their baby if infected, while those with compromised immunity are especially vulnerable.

Outlook Hinges on Vaccination Drive

The extent of future spread likely depends on rapidly improving vaccination rates over the coming months. Most unvaccinated people getting measles now were too young for MMR shots during early phases of the COVID pandemic – so there are substantial susceptible cohorts.

Sustained outbreaks could see the UK lose its “measles-free” status, with WHO warning anywhere below 95% coverage risks continuous transmission.

However, if MMR uptake climbs back towards target soon, we may avoid worse scenarios.

“This outbreak is a stark reminder of how quickly hard-won gains can unravel if we don’t maintain high immunity across communities,” said Chief Medical Advisor Dr. Hopkins. “Our message to parents is clear – make sure your children are up to date with MMR to protect themselves and others.”
