Measles & Rubella Weekly Monitoring Report: November 16 to November 22, 2014 (week 47)

Key Points

  • In Canada, no new cases of measles were reported during week 47.
  • On November 13, the World Health Organization issued a news release warning that international progress towards measles elimination has stalled. Agreed to at the 2010 World Health Assembly, milestones for 2015 (related to increasing immunization coverage and decreasing measles incidence and mortality) may not be metFootnote 1.
  • Pakistan continues to experience a high level of measles activity with 1288 confirmed cases reported so far this yearFootnote 2.

Epidemiological Summary

Figure 1. Number of cases measles (n=127) and rubella (n=1), by week of rash onset, as reported to the Canadian Measles/ Rubella Surveillance System (CMRSS) and Measles and Rubella Surveillance system (MARS), for the period ending November 22, 2014. Among these, rash onset is not currently available for 25 cases; they have been excluded from the figure but included in the year-to-date total below.

Laboratory Summary

Measles

Genotyping is pending for 0 cases.

For 2014, measles genotype information is available for 111 of 127 reported cases and the genotypes were: B3 (n=65), D8 (n=36), D9 (n=5), H1 (n=3), and D4 (n=2).

Figure 3: Distribution of measles genotypes detected in 2014 (n=111) by week of rash onset (if available, n=85) or specimen collection (n=26). Epidemiological weeks are assigned in accordance with WHO guidelines (WHO.WER.2012;9(87):73) with week 1 beginning on the first Monday of the year.
