In March 2014 an outbreak of measles commenced in a small religious school attended by around 350 children from families with extremely low MMR vaccination uptake. Within 4 weeks almost 400 cases were observed within the 1200 member congregation. Only four cases occurred unlinked to the congregation. While importations of measles into Canada are expected and rapid spread is possible in unimmunized communities, public health measures can control outbreaks.
