Measles elimination: Outbreak of measles in an unvaccinated population, British Columbia, 2014

Background Although Canada eliminated endemic measles in 1998, outbreaks are expected to occur periodically through import-related transmission in geographically clustered unvaccinated communities. In the spring of 2014, in association with an outbreak in the Netherlands, a large measles outbreak occurred in British Columbia in a community unvaccinated for religious reasons.
