Measles is making a dangerous comeback — and it’s entirely preventable. Despite being a vaccine-preventable disease, measles cases are rising in Ontario, Canada, and globally, sparking concern among health experts. But here’s the part most people miss: measles isn’t just a childhood illness with a rash—it’s a highly contagious virus that can lead to severe complications like pneumonia, brain swelling, and even death, especially in vulnerable populations. So, why is it resurging, and what can we do about it? Let’s dive in.
The Alarming Return of Measles
Dr. Susy Hota, Division Head for Infectious Diseases and Medical Director for Infection Prevention and Control at UHN, warns, ‘In the past year and a half, we’ve seen a resurgence of measles—but we have the tools to stop it.’ The key? Vaccination. Yet, misinformation and vaccine hesitancy are fueling its spread. And this is where it gets controversial: Some argue that natural immunity is better than vaccination, but the risks of contracting measles far outweigh any perceived benefits of avoiding the vaccine.
What Is Measles, and How Does It Spread?
Measles, also known as rubeola, starts with symptoms like fever, cough, runny nose, and red eyes. Around day four, a blotchy red rash appears, starting on the face and spreading downward. The illness typically lasts 10 to 14 days but can cause severe complications, particularly in babies, pregnant individuals, and those with weakened immune systems.
Here’s the shocking part: measles is one of the most contagious diseases in the world. It spreads through tiny airborne particles when an infected person coughs, sneezes, or even breathes in shared spaces. These particles can remain infectious in the air for up to two hours. Even more alarming? An infected person can spread the virus up to four days before the rash appears. Think about it: 90% of unvaccinated individuals exposed to measles will get it.
Can Measles Be Deadly?
Absolutely. While many recover, complications like pneumonia, encephalitis (brain swelling), and long-term neurological effects can occur. In Canada, deaths are rare but remain a risk for vulnerable groups. The rash itself, though not typically itchy, is a stark warning sign of infection.
Treatment and Prevention
There’s no specific antiviral treatment for measles. Managing symptoms—like staying hydrated, avoiding bright lights, and caring for irritated eyes—is key. But the best defense? Vaccination. The measles vaccine was first introduced in 1963, with a safer version in 1968. Today, the Measles-Mumps-Rubella (MMR) and Measles-Mumps-Rubella-Varicella (MMRV) vaccines are widely used. Two doses, given at least four weeks apart, provide about 98% lifelong protection.
Is the Vaccine Safe?
Yes, overwhelmingly so. Side effects are usually minor, like a low-grade fever or mild rash. Rare reactions, such as febrile seizures in children, are far less common than measles complications. But here’s a thought-provoking question: If the vaccine’s risks are so minimal compared to the dangers of measles, why do some still hesitate? Could it be misinformation, fear, or a lack of trust in medical institutions? Let’s discuss in the comments.
What Should You Do If You Suspect Measles?
Seek medical attention immediately—but call ahead so the facility can isolate you upon arrival. Don’t risk spreading it further.
Conclusion: The Power to Stop Measles Is in Our Hands
Measles is preventable, and vaccination is the most effective way to protect yourself, your loved ones, and your community. Don’t wait—check your vaccination status today. Visit Health Canada’s Immunization Guide or your local public health agency for resources. Together, we can halt this preventable disease in its tracks.
Final Thought: No single person can change the world alone, but when communities, healthcare professionals, and organizations like UHN work together, we can redefine healthcare and eradicate diseases like measles. What’s stopping us from taking action today? Share your thoughts below—let’s start a conversation that could save lives.
