Origins and Transmission Dynamics

Health officials have traced the outbreak to a multi-territorial event.

• Initial Case: The outbreak originated with a case linked to travel to New Brunswick.
• Spread: The virus then spread to Ontario and Manitoba.
• Mennonite Community Link: An Ontario public health official noted that the outbreak is linked to a large gathering of mennonite communities in New Brunswick last fall, where subvaccination and exposure to measles in certain regions played a role.

Cases disproportionately affect certain Mennonite, Amish communities and other anabaptist communities due to a subvaccination and exposure to measles in certain regions.
Dr. Kieran Moore, Ontario Public Health Official

Measles is exceptionally contagious. According to the World Health Association,the virus can persist in the air or on surfaces for up to two hours [[2]].

vaccination Efforts and Challenges

Public health units are responding to the outbreak with targeted vaccination strategies.

• Early Vaccination: While the measles vaccine is typically administered at one year of age,Ontario public health offices have made the first dose available to babies as young as six months in response to the outbreak.
• School Response: Following a measles case at Walsingham Christian School, a private school connected to the Mennonite Old Colony church, an impromptu meeting was held with parents to discuss vaccination.Information in Low German was provided to parents who were not fluent in English.
• Community Stance: The school director emphasized that the decision to vaccinate is a personal one, unrelated to their religious beliefs.

The decision of families to have their children vaccinated or not has nothing to do with our baptismal vision of religion. Absolutely nothing. Our ministers, our church, our community, we would not disseminate an opinion on vaccination.
Martin Klassen, Director, walsingham Christian School

Access to family doctors for routine vaccinations remains a challenge for many in Ontario.
