Epidemiological Summary

During epidemiological week 10, 2016, 2 new cases of measles were reported by British Columbia and OntarioFootnote 1. Both cases had rash onset in week 09, and both were importations exposed to measles during separate travel to Pakistan (cases are unrelated).

No cases of rubella were reported. It has been 105 weeks since the last reported rubella case (week 10, 2014).

The year-to-date total is 4 cases of measles and 0 cases of rubella for 2016 (Figure 1).
