Phylogenetic analysis of the newly derived near full-length sequence 02CMLT72 and their relatedness. All reference subsubtypes and available CRFs were initially used to construct the tree; some references have been omitted for clarity. Reference strains are identified by subtype or CRF number classification followed by sequence ID. The scale bar represents 2% genetic distance. Sequences from Cameroon specimens are indicated as •, 02CMLT72; ▪, 02CM1867LE; ○, 02CM3097MN; ▵, 01CM53122; ⋄, 01CM001BBY; and □, 02CM1917LE throughout the article. Bootstrap values above 70% are shown; numbers at the nodes of the tree represent maximum parsimony bootstrap values.
