Spain Sees Early Surge in Measles Cases as Experts Warn of Spring Spread Risk

Spain Second in EU for Measles Cases

Spain has emerged as the second most-affected country in the European Union for measles in 2026, with 101 cases recorded in just the first two months of the year. Across Europe, the European Centre for Disease Prevention and Control documented 350 total cases during January and February alone.

Over the past 12 months, more than 4,600 cases have been reported across EU and EEA countries — a clear signal that the disease, long considered under control in Western Europe, is making an unwelcome comeback.

Why the Concern Is Growing Now

Health specialists warn that spring is a particularly high-risk period for transmission. Warmer weather brings increased indoor gatherings during Easter, family reunions and travel — conditions in which a highly contagious airborne virus like measles can spread quickly.

Measles is one of the most contagious diseases known to medicine. Each infected person can pass the virus on to 15 to 20 unvaccinated individuals, and the virus "can linger for hours" in enclosed spaces even after an infected person has left the room.

Who Is Most at Risk

According to Dr. Pablo García Montes, measles "primarily affects children, although it can also occur in unvaccinated adults." The data backs this up starkly:

• More than 90% of infections occur in unvaccinated people
• Nearly 80% of those infected across the EU/EEA had received no vaccine doses at all
• Up to 30% of infected children experience complications

The pattern is consistent: where vaccination coverage dips, outbreaks follow.

It Is Not a Trivial Disease

Dr. José Ramón García López has stressed that measles "is not a trivial disease", pointing to a range of serious potential complications, including:

• Pneumonia
• Ear infections (which can lead to hearing loss)
• Febrile seizures
• Encephalitis — inflammation of the brain, which can be fatal

While most people recover, the risk of severe illness is real — particularly in young children, pregnant women and people with weakened immune systems.

Recognising the Symptoms

Measles typically begins with flu-like symptoms before the characteristic rash appears. Key signs include:

• High fever
• Runny nose and cough
• Red, watery eyes (conjunctivitis)
• Small white spots inside the mouth (Koplik's spots)
• A red, blotchy rash that starts on the face and spreads down the body

Anyone who suspects measles should contact their health centre by phone first rather than attending in person, to avoid exposing other patients in the waiting room.

Vaccination Remains the Best Defence

The MMR vaccine — which protects against measles, mumps and rubella — is the single most effective tool against outbreaks. Two doses provide over 95% protection and, when uptake is high enough in a community, enable herd immunity — protecting those who cannot be vaccinated, including very young babies and immunocompromised individuals.

In Spain, the MMR vaccine is offered free of charge to children under the national immunisation schedule. Adults who are unsure of their vaccination status, or who were born before widespread MMR rollout, can ask their GP (médico de cabecera) for advice on whether a catch-up dose is recommended.

What to Do If You Think You Have Been Exposed

If you believe you or your child may have been exposed to measles:

• Call your local health centre (centro de salud) before visiting in person
• Check your vaccination records — two MMR doses is the gold standard
• Avoid contact with infants, pregnant women and anyone with a weakened immune system until advised
• In an emergency, call 112

With spring travel and public events ramping up, health authorities are urging anyone who has not received two MMR doses to speak to their doctor. Vaccination is free, safe, and — as Spain's early 2026 surge shows — very much needed.
