Phylogenetic trees of the sequences derived from the core and NS5B regions of the putative recombinant viruses described in this work. The neighbour-joining tree is based on the core (a) and NS5B (b) sequences. The sequences of putative recombinant viruses described here are shown in bold. Previously reported recombinants in Cameroon are underlined [18]. The reliability of the tree topologies was estimated by bootstrap analysis with 1000 pseudoreplicate data sets and for clarity, all bootstrap less than 70 have been omitted
