Identification of measles virus genotypes from recent outbreaks in countries from the Eastern Mediterranean Region

The Tunisian and Libyan epidemic strains belonged to genotype B3, they were closely related to each other and to isolates from Western Africa. The Syrian and Iranian viruses belonged to genotype D4, and differed from each other and from the other published sequences within this genotype. Our results provide valuable baseline and new tools for improved virological measles surveillance in the future, at country, regional and global levels.
