This report presents the epidemiology of measles in Canada between 2002 and 2013 and its implications in sustaining measles elimination.<\/jats:p><jats:p>Methods. \u2003Cases included individuals reported to the Canadian Measles and Rubella Surveillance System with confirmed measles.<\/jats:p><jats:p>Results. \u2003In Canada, 1171 cases of measles were reported between 2002 and 2013 (incidence 0.29 cases per 100 000 population). The annual number of cases ranged from 6 to 752. The majority of cases were unvaccinated (63%) or had an unknown vaccination status (19%). The median age of cases was 14.4 years (range, &amp;lt;1 to 63 years) globally and 14 years when excluding the 2011 outbreak in Quebec where 68% of the 678 cases were 10 to 19 years old. With the exclusion of this outbreak, the incidence was highest in infants (1.0 per 100 000), lower but fairly similar between 1 and 19 years of age (0.2 to 0.4 per 100 000), and there was a substantial decline between 20 and 39 years of age (0.1 per 100 000). There was a significant trend towards a greater annual number of importations over the period. Although importations resulted in no transmission sustained for \u226512 months, 5 chains of transmission had &amp;gt;30 cases. The effective reproductive number between 2002 and 2013 was estimated at 0.86 (95% confidence interval, .81\u2013.92).<\/jats:p><jats:p>Conclusions. \u2003Canada has maintained elimination between 2002 and 2013, but additional efforts are needed to reduce the proportion of unimmunized individuals and respond to importation events.<\/jats:p>","DOI":"10.1093\/ofid\/ofv048","type":"journal-article","created":{"date-parts":[[2015,4,17]],"date-time":"2015-04-17T00:51:21Z","timestamp":1429231881000},"source":"Crossref","is-referenced-by-count":15,"title":["Measles
