NHS Doctor Highlights '90%' Measles Contagion Risk in UK Outbreak
An NHS doctor has issued a stark warning, stating there is a 90 per cent chance of contracting measles for unvaccinated individuals exposed to the virus, amid a serious outbreak across the United Kingdom. The UK is among several nations experiencing record-high cases of this potentially fatal disease, with health officials confirming a fast-spreading outbreak in multiple north London schools, primarily affecting unvaccinated children under the age of 10.
Measles Cases and Data Trends
According to the latest figures from the UK Health Security Agency (UKHSA), England has reported 96 laboratory-confirmed measles cases since January 1 this year. This follows a troubling trend from previous years: in 2025, there were 959 cases, and in 2024, the number soared to 2,911, marking the highest annual tally since 2012. Between 2019 and 2025, measles was linked to 20 deaths, a figure that matches the total recorded over the 19-year span from 1999 to 2018.
Doctor's Personal Experience and Global Context
In a video shared on TikTok, NHS doctor Suraj Kukadia, known online as Dr Sooj, emphasised the critical role of vaccines. He recalled that seeing measles patients was once rare, noting, "I remember the first time I saw a measles rash. It was only a couple of years ago. I diagnosed it incorrectly because I'd never actually seen it before. Now, most GPs my age haven't or hadn't. That's how successful vaccination has been." From 2021 to 2023, Britain was considered to have eliminated measles, but the resurgence is attributed to a significant drop in vaccination rates.
Dr Sooj highlighted the global scale of the issue, pointing out that the United States recorded over 1,900 cases in 2025, the highest in three decades, and Canada lost its elimination status. He stressed, "This is serious." The UKHSA has warned that uptake of routine childhood vaccinations is at its lowest in a decade, well below the 95 per cent threshold needed to maintain herd immunity and prevent outbreaks.
Vaccination Efficacy and Herd Immunity
Dr Sooj explained that the MMR vaccine, offered free on the NHS, is 93 per cent effective after one dose and 97 per cent effective after two doses. He warned, "If you're in a room with someone who has measles and you're unvaccinated, there's a 90 per cent chance that you'll catch it," a statistic supported by the National Foundation for Infectious Diseases. Achieving 95 per cent vaccination coverage is crucial to protect vulnerable groups, such as babies, immunocompromised individuals, and pregnant women.
Symptoms and Prevention Measures
Measles often begins with cold-like symptoms, including:
- A high temperature
- A runny or blocked nose
- Sneezing
- A cough
- Red, sore, watery eyes
Small white spots may appear inside the cheeks and on the back of the lips, followed by a distinctive rash that starts on the face and spreads across the body. The NHS advises seeking an urgent GP appointment or contacting NHS 111 if measles is suspected.
To prevent spread, individuals should:
- Stay off nursery, school, or work for at least four days after the rash appears.
- Avoid close contact with vulnerable groups like babies, pregnant women, and those with weakened immune systems.
- Open windows and doors to improve ventilation.
- Wash hands frequently with soap and warm water.
- Use tissues when coughing or sneezing and dispose of them immediately.
- Refrain from sharing cutlery, cups, towels, clothing, or bedding.
Dr Sooj concluded with a plea: "Please get vaccinated. Keep your children vaccinated. Measles is entirely preventable, but only if we maintain a high vaccination coverage." Those unsure about their vaccination status should consult their GP surgery for free NHS vaccination.
