Overview of the Outbreak

In a startling revelation, a measles outbreak that has affected numerous unvaccinated children in Southwestern Ontario is traced back to a large Mennonite gathering in New Brunswick last fall. The situation has raised alarms among health officials and parents alike, as the outbreak puts unvaccinated communities at risk.

Origin of the Outbreak

In a memo dated March 7, Dr. Kieran Moore, Ontario’s Chief Medical Officer of Health, highlighted the outbreak's origins, linking it to an event attended by members of the Mennonite community. Attendees from this gathering unknowingly returned home to Southwestern Ontario, sparking the spread of the virus primarily in regions bordering Norfolk, Oxford, and Elgin counties, where conservative Mennonite populations reside.

Further Spread to Manitoba

The outbreak took a broader turn, as it subsequently affected Mennonites in Manitoba when they returned from visiting family in Ontario. Initial reports indicated that the measles virus entered Canada on October 16 of the previous year, when an infected traveler arrived in New Brunswick from the Philippines, after stops in Vancouver and Toronto. However, the specific route of transmission to Southwestern Ontario was unclear until Dr. Moore's communication.

Current Statistics

According to the latest data from Public Health Ontario, as of March 20, the region has recorded a staggering 223 confirmed measles cases since last October, with another 111 reported in nearby Grand Erie. Remarkably, these cases account for nearly three-quarters of Ontario’s total measles cases, predominantly affecting unvaccinated individuals.

Vaccine Hesitancy Symptoms

While health officials in West Texas have similarly pointed to low vaccination rates in Mennonite communities for recent outbreaks, local authorities in Ontario have been cautious about directly attributing vaccine hesitancy to the current rise in cases among conservative Mennonites.

Exposure Sites

Exposure sites detailed by health officials in Grand Erie, including churches and private schools frequented by Old Colony Mennonites, affirm these claims. Dr. Moore noted in his memo, “Cases could spread in any unvaccinated community but are disproportionately affecting some Mennonite, Amish, and other Anabaptist communities due to a combination of under-immunization and exposure to measles.”

Community Messages on Vaccination

In a proactive approach during the COVID-19 pandemic, leaders from Mennonite Church Canada sought to dispel myths regarding vaccination, stating there is no scriptural justification for declining vaccinations. However, a spokesperson for the organization clarified that the Old Colony Mennonites do not fall under their denomination and did not return queries regarding current messaging on the measles vaccine.

Encouragement from Local Leaders

A local Mennonite pastor, unrelated to the outbreak, encouraged her congregation to consult medical professionals if they had doubts about vaccinations, highlighting the importance of informed health decisions.

Preventive Measures

The best preventive measure against measles, according to health officials, is for individuals born after 1970 to receive two doses of the Measles, Mumps, and Rubella (MMR) vaccine. Vaccination is typically administered soon after a child’s first birthday, with a follow-up dose between age four and six. Additionally, children in Southwestern and Grand Erie can now receive a first dose as early as six months.

Monitoring Vaccine Supply

Dr. Moore assured that the vaccine supply is being monitored closely, with additional doses being ordered as necessary. The measles virus has emerged in 11 health units and the city of Hamilton this year, with local health officials linking many cases back to the ongoing outbreak.

Health Risks of Measles

While many individuals recover from measles with proper care, the virus can severely compromise the immune system; in extreme cases, it can lead to brain damage or deafness. Tragically, there was a report of a child who died from measles in Hamilton last year.

Conclusion and Reminder

As this story unfolds, it serves as a pressing reminder of the critical need for vaccinations and the vulnerabilities that communities face when vaccine hesitancy prevails. Stay informed as we follow this developing story, and don’t let misinformation put your family at risk!
