Laboratory summary

Measles

In 2019, seventy-three (73) cases of measles have been genotyped and the genotypes were B3 (n=20) and D8 (n=53), both of which are circulating globally.

Footnote †

Epidemiological weeks for laboratory specimens submitted to the National Microbiology Laboratory are assigned and reported in accordance with WHO guidelines (WHO.WER.2012;9(87):73) with week 1 beginning on the first Monday of the year, which for 2019 is January 7. However, for the purposes of this report, the genotype data is presented in accordance with PAHO reporting weeks with week 1 of 2019 beginning on December 30, 2018.
