Measles: More Than Just a "Mild Childhood Illness" – A Real Risk for All

In recent years, measles has made a strong comeback worldwide, disproving the myth that it’s just a harmless childhood illness. The rise of anti-vaccine misinformation has left millions vulnerable, leading to an increase in cases—even among adults. Why is this happening, and how can we protect ourselves?

The Measles Comeback: A Global Wake-Up Call

Measles was nearly eradicated in many countries thanks to vaccination, but the anti-vaccine movement has caused a dangerous resurgence. According to the WHO, more than 16,000 measles cases have been confirmed globally in 2025, with significant outbreaks in the United States, Yemen, Pakistan, and India. In Mexico alone, there have already been 22 confirmed cases this year, and 86% of those infected were unvaccinated​.

Measles is an extremely contagious viral disease, spreading through the air via droplets from talking, coughing, or sneezing. It is one of the most infectious diseases, with a single infected person capable of transmitting the virus to up to 18 unvaccinated individuals.

Why Is Measles Still Dangerous?

Many people mistakenly believe that measles only causes a mild rash, but this disease can lead to severe complications, including:

• Pneumonia, a leading cause of death in measles-infected children.
• Encephalitis, brain inflammation that can cause permanent neurological damage.
• Middle ear infections (otitis media), potentially leading to hearing loss.
• Death, particularly in malnourished or immunocompromised individuals.

In areas with poor medical access, the fatality rate can reach 10%

​

Are Adults at Risk? Absolutely!

Contrary to popular belief, adults can also develop severe measles complications, especially if they were never vaccinated or didn’t complete their immunization schedule. In Mexico, 18% of confirmed cases this year have been in adults aged 25 to 44​.

Measles symptoms in adults tend to be more severe, often requiring hospitalization. Additionally, measles during pregnancy can lead to preterm birth and serious complications for the baby.

The Only Real Protection: Vaccination

The best way to prevent measles is through the MMR vaccine (measles, mumps, and rubella), which is administered in two doses:

• First dose at 12 months of age.
• Second dose between 18 months and 6 years, depending on the updated vaccination schedule.

For unvaccinated teenagers and adults, the MR (measles-rubella) vaccine is recommended.

In Mexico, most measles cases have occurred in unvaccinated individuals. Vaccination not only protects the person receiving the shot but also creates a community-wide shield, preventing the virus from spreading.

The Cost of Misinformation

Anti-vaccine conspiracy theories have led thousands to refuse immunization, putting their children and entire communities at risk for preventable diseases. There is no scientific evidence linking the measles vaccine to autism, a myth that has been repeatedly debunked in multiple studies.

Every unvaccinated individual weakens the chain of immunity, allowing the virus to spread and endangering vulnerable groups such as infants, pregnant women, and immunocompromised individuals.

It’s Not Too Late to Protect Yourself

If you’re unsure whether you’re vaccinated against measles, check your immunization records or visit a healthcare center. Getting vaccinated is not just a right—it’s a collective responsibility.

Measles is no joke. Prevention is in our hands.
