Fig. 4From: Spatio-temporal spread and evolution of Lassa virus in West AfricaTanglegram between phylogenetic trees of LASV segments. Phylogenetic trees of the L segment and S segment were constructed using ML. each colour represented one lineage, and the green dots at the end of the tree was a strain. And those strains with different topological structures in the two segments were connected by red linesBack to article page
