Measles is a remarkably contagious viral infection that poses serious health risks, including pneumonia and encephalitis, which is inflammation of the brain. Alarmingly, despite being preventable, there has been a noticeable increase in measles cases not only in Ontario and across Canada but also around the world.
Dr. Susy Hota, who serves as the Division Head for Infectious Diseases and the Medical Director for Infection Prevention and Control at UHN, states, "In the past year and a half, we have seen a resurgence of measles — but we have the power to stop it."
The most effective way to safeguard both yourself and your community from this disease is through vaccination. Continue reading to discover more about measles and the ways you can help combat its spread.
Measles, also known as rubeola, is a viral condition that typically begins with symptoms such as fever, cough, runny nose, and red eyes. Around the fourth day of illness, a distinctive red rash appears, starting on the face and progressively spreading downward across the body.
The duration of the illness generally ranges from 10 to 14 days, and it can lead to severe complications, particularly among infants, pregnant individuals, and those with weakened immune systems.
So, how does measles actually spread?
This virus transmits through tiny particles released into the air when an infected person coughs, sneezes, or even breathes in shared spaces. These infectious droplets can linger in the air for up to two hours, posing a risk to anyone who enters the area.
Individuals with measles are contagious for up to four days before they exhibit the characteristic rash. Shockingly, approximately 90 percent of unvaccinated people exposed to the virus will contract it, making measles one of the most easily spread diseases globally.
Can measles be fatal? Yes, it certainly can. While many patients recover, serious complications such as pneumonia, encephalitis, and lasting neurological issues can occur. Although deaths from measles are rare in Canada, certain vulnerable populations — including infants, pregnant individuals, and those with compromised immune systems — face a significantly higher risk.
Is the measles rash itchy? The classic measles rash is typically red and blotchy, usually originating on the face and moving downward. While the rash may not itch like some others, it can be uncomfortable and serves as a clear sign of infection.
What about treatment options for measles?
Currently, there is no specific antiviral treatment available for measles. To alleviate symptoms, it's crucial to stay hydrated, minimize exposure to bright lights, and care for your eyes. However, the best preventive measure remains vaccination.
When was the measles vaccine first developed? The original measles vaccine was introduced back in 1963, followed by a safer version in 1968. Nowadays, the widely administered vaccines include the Measles-Mumps-Rubella (MMR) and the Measles-Mumps-Rubella-Varicella (MMRV) vaccines.
To achieve complete vaccination, individuals should receive two doses of either the MMR or MMRV vaccine, spaced at least four weeks apart. It is also advised that adults who were vaccinated between 1963 and 1968 consult their healthcare provider regarding a booster shot.
Is the measles vaccine safe? Absolutely! The measles vaccine is both safe and highly effective. Most side effects are minor and temporary, such as a slight fever or a mild rash. Serious reactions, like febrile seizures in children or temporary drops in platelet levels, are exceedingly rare compared to the risks associated with measles itself.
When evaluating the potential severity of measles complications, including pneumonia, encephalitis, or even death, the advantages of vaccination far exceed any possible risks.
How often should individuals get vaccinated? Two doses of the MMR vaccine generally provide about 98 percent protection for life. Most adults who received both doses during childhood do not require a booster.
If you're uncertain about your vaccination status, it's wise to check your health records or have a conversation with your healthcare provider.
What steps should you take if you suspect you have measles? It's crucial to seek medical attention promptly; however, make sure to inform the healthcare facility beforehand so they can prepare to isolate you upon your arrival.
In summary, measles is a preventable disease — and vaccination remains the most effective strategy to protect yourself, your children, and the wider community. If you're looking to find where to get vaccinated or verify your vaccination status, consider visiting Health Canada's Immunization Guide or your local public health agency for details on clinics, pharmacies, and health centers near you.
