Distribution of RVFV lineages in Africa and Middle East. A Lineages reported in Africa and the Middle East (Saudi Arabia) sampled between 1944 to 2016. B Map of Africa and Saudi Arabia indicating the number RVFV sequences for the M-segment (partial and complete) as of 28th May 2021 for the 129 sequences used in the lineage assignment. C Maximum likelihood phylogenetic tree using glycoprotein (Gn) representative sequences (n = 51) showing geographical distribution of lineages. The tips of the tree are colored according to their country of origin. CAR, Central African Republic
