From: Genetic characterization of measles virus circulating in Iran, 2021–2023
Phylogenetic analysis of Iranian measles sequences (B3) using the N-450 region during 2021–2023 alongside B3 reference sequences and WHO named-strains using FigTree software. 2021 strains are displayed with purple colour, 2022 strains are displayed with red colour and 2023 strains are displayed with green colour. WHO named-strains (MVs/Islamabad.PAK/1.13, MVs/Quetta.PAK/44.20 and MVs/Oslo.NOR/16.18) are displayed with blue colour. MVs/Muscat.OMN/25.17 and MVs/Quebec.CAN/17.19 have the most similarity with cluster B3.2 sequences and are shown in black colour. B3 reference sequences are displayed with pink colour. Reference sequences belonging to other measles genotypes are compressed and shown by dark triangle
