Laboratory Summary
Measles
To date in 2015, 55 measles cases have been genotyped and the genotypes were: B3 (n=22), D4 (n=17), H1 (n=11) and D8 (n=5).
Figure 3: Distribution of measles genotypes detected in 2015 (n=55) by week of rash onset (if available, n=55) or specimen collection (n=0). 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.
* Genotype B3 sequences identical to sequence variant MVi/Harare.ZWE/38.09 (GenBank accession number JF973033)
