Measles: A Global Health Concern and How to Protect Your Child
In a worrying development, London is currently facing a measles outbreak, primarily impacting unvaccinated children under 10. This comes at a time when global measles infections are on the rise. The UK, along with five other countries, recently lost its measles-free status granted by the World Health Organization (WHO), highlighting the urgency of the situation.
What's Measles and How Does It Spread?
Measles is a highly contagious viral illness that spreads easily among unvaccinated individuals. It typically starts with cold-like symptoms, followed by a distinctive rash a few days later. This rash begins on the face and behind the ears, gradually spreading to the entire body. The measles rash is characterized by raised spots that may join together, forming blotchy patches. Some individuals may also develop small spots inside their mouths.
The virus spreads through breathing, coughing, or sneezing. One infected person can cause up to 18 secondary infections. If exposed, nine out of ten unvaccinated individuals will contract measles. An infected person is contagious from the onset of symptoms (approximately four days before the rash appears) until four days after the rash develops.
Health experts recommend simple measures to reduce the risk of transmission: opening windows and doors for ventilation, frequent handwashing with soap and warm water, and using tissues when coughing or sneezing, followed by immediate disposal.
It's important to avoid sharing cutlery, cups, towels, clothes, or bedding to minimize the chances of infection.
Understanding the Risks
While many people recover from measles, it can lead to serious complications such as pneumonia or brain inflammation. In rare cases, it can result in long-term disabilities or even death. Babies and individuals with weakened immune systems are at higher risk. Measles can also cause miscarriage, stillbirth, premature birth, and low birth weight in babies.
Despite the availability of a safe and cost-effective vaccine, the WHO reports that there were 95,000 measles deaths globally in 2024, with most victims being unvaccinated children under five.
The Rise in Measles Cases
Measles is entirely preventable with vaccination, but its high contagiousness makes it one of the first illnesses to resurge when vaccine rates drop. Health experts attribute the increasing number of measles outbreaks worldwide to growing mistrust and skepticism towards vaccines post-COVID-19 pandemic.
In January, the UK lost its measles-free status, granted by the WHO when a country has had no endemic cases for at least 12 months. Spain, Austria, Armenia, Azerbaijan, and Uzbekistan also lost their status.
Experts emphasize that this is a global challenge, with several European nations, including France and Romania, already experiencing regular measles transmission. Canada lost its elimination status in 2025, and the US is also facing a rise in infections while trying to retain its measles-free status.
The Solution: Herd Immunity
According to the WHO, the only way to prevent measles is through herd immunity, which requires a vaccination coverage of 95%. This high threshold is necessary because measles is one of the most infectious diseases globally, remaining contagious in the air or on surfaces for up to two hours.
In the UK, only 84% of children received the two doses required for full protection in 2024. This resulted in 2,911 confirmed cases in England that year, the highest since 2012. Globally, the proportion of children receiving the first dose of the measles vaccine was also 84% in 2024, below the 2019 level of 86%.
Protecting Your Child
There is no specific treatment for measles, but two doses of the measles vaccine provide high levels of protection and help prevent further outbreaks. Both the MMRV and MMR vaccines offer protection against measles, mumps, and rubella, with the MMRV vaccine also providing protection against chickenpox. The MMRV vaccine is typically administered to children at 12 and 18 months of age.
Recognizing the Signs and Symptoms
Symptoms of measles usually appear 10 to 14 days after exposure to the virus. The most noticeable sign is the prominent rash. Early symptoms, which tend to last between four and seven days, include a runny nose, cough, red and watery eyes, and small white spots inside the cheeks. The rash typically begins about seven to 18 days after exposure, starting on the face and upper neck, and gradually spreading to the hands and feet over three days. It can persist for up to a week before fading.
And here's where it gets controversial...
With the rise in anti-vaccination sentiments, it's crucial to have an open dialogue about the importance of vaccination. What are your thoughts on the matter?
