Phylogenetic tree of RVFV generated by the maximum likelihood method with bootstrap (500 replicates) based on 1690 nucleotides of the S genomic segment of RVFV. Analysis involved 125 sequences available in GenBank. Compressed Cluster 1 includes 41 sequences collected in Kenya in 2007 and in Madagascar and South Africa in 2008; Cluster 2: nineteen sequences collected in Sudan, Kenya, and Tanzania in 2007, in Sudan in 2010, and in Uganda in 2016; Cluster 3: thirteen sequences from Egypt, South Africa, Madagascar, and Zimbabwe, collected from 1951 to 1994; Cluster 4: eleven sequences from Zimbabwe, C.A.R., Guinea, and Zambia, collected between 1969 and 1985; Cluster 5: three sequences from Saudi Arabia (2000–2001); Cluster 6: three sequences from Egypt and Madagascar (1978–1991); Cluster 7: nine sequences from Kenya and South Africa, collected between 1951 and 1975. Strain names and accession numbers of the sequences included in the compressed clusters are listed in Table S4.
