Fig. 3From: The global spread of Middle East respiratory syndrome: an analysis fusing traditional epidemiological tracing and molecular phylodynamicsTime-scaled phylogeographic tree of MERS-CoV ORF1a/b sequences isolated from humans and camels. Each color shown in legend represents city or region of sampled sequence (tip branches) as well as ancestral lineage (internal branches) inferred by Bayesian phylogeography. Vertical blue lines encompass sequences collected at the time of outbreaks and brown camel symbols indicate sequences isolated from camels. An asterisk (*) along the branch represents the posterior probability for each clade greater than 0.90. Double asterisks (**) indicate > 0.95. Triple asterisks (***) indicate >0.99Back to article page
