Laboratory Summary

Measles

To date in 2016, 2 measles cases have been genotyped and the genotypes were B3 (n=1) and D8 (n=1) (Figure 3).

One case reported by British Columbia, with travel history in the Western Pacific Region, was genotype D8, identical to the sequence variant MVi/Hulu Langat.MYS/26.11 (GenBank accession number JX486001). Measles genotype D8 has been associated with imported cases in the Western Pacific Region.

Epidemiological weeks for laboratory specimens are assigned in accordance with WHO guidelines (WHO.WER.2012;9(87):73) with week 1 beginning on the first Monday of the year.
