Measles is a highly contagious viral infection that primarily affects young children but can also impact adults. Recently, Haldimand County has seen a surge in measles cases, raising public health concerns. Here’s a quick rundown of what you need to know about measles, its symptoms, and the importance of vaccination.

What Is Measles?

Measles is a viral infection that spreads through respiratory droplets when an infected person coughs or sneezes. It is one of the most contagious diseases and can spread easily among people who are not vaccinated.

Symptoms of Measles

The typical symptoms of measles appear about 10–14 days after exposure and include:

  • High fever
  • Cough
  • Runny nose
  • Sore throat
  • Red, watery eyes
  • Rash that usually starts on the face and spreads to the rest of the body

In some cases, measles can lead to serious complications like pneumonia, brain inflammation, and even death, particularly in young children, pregnant women, and individuals with weakened immune systems.

Measles Outbreak in Haldimand, Ontario

As of early 2025, Haldimand County has experienced a measles outbreak, with the total number of cases in Ontario surpassing the previous year’s count. Public health officials have pointed out that the outbreak is primarily affecting individuals who are unvaccinated or under-vaccinated. The outbreak underscores the importance of maintaining high vaccination rates in the community to prevent the spread of this virus.

Why Vaccination Matters

Vaccination is the most effective way to prevent measles. The measles, mumps, and rubella (MMR) vaccine is safe, highly effective, and widely available in Ontario.

Public Health has recommended the following vaccination guidelines during this outbreak:

  • Infants aged 6 to 11 months should receive one dose of the measles vaccine.
  • Children >1 year old and adults born after 1970 should receive two doses of the MMR vaccine to be fully protected.
  • Adults who received only one dose should get a second dose to ensure full immunity.

The vaccine not only protects you but also helps protect those around you by creating herd immunity. This is especially important in communities where vaccination rates are low.

Public Health Guidelines

To reduce the risk of measles, public health authorities in Ontario recommend:

  • Getting vaccinated: Ensure you and your children are up-to-date with the MMR vaccine.
  • Avoiding contact with infected individuals: If you suspect you have measles, stay home and avoid close contact with others to prevent spreading the virus.
  • Monitoring for symptoms: If you’ve been exposed to someone with measles, watch for symptoms, and seek medical attention if necessary.

Final Thoughts

Measles is a serious disease, but it’s preventable through vaccination. The recent outbreak in Haldimand serves as a reminder of the importance of keeping up with your immunizations. If you’re unsure about your vaccination status or need more information, talk to your healthcare provider or visit your local public health unit.
