Figure 4. Phylogenetic Analysis of New World Mammarenaviruses, Including Chapare mammarenavirus Species.

Figure 4.

The phylogenetic tree shows relatedness between representative New World mammarenavirus S segments (Panels A and B) and L segments (Panels C and D) from clades A, B, and C, and 2019 Chapare virus sequences obtained from seven patients and two rodents (Oligoryzomys microtis) in the 2019 CHHF outbreak in Bolivia. The GenBank accession numbers of the sequences used in the phylogenetic analysis are listed in parentheses after the patient number and the location and date of specimen collection. The GenBank numbers of other viruses follow the virus names. The scale bars denote the genetic distance in nucleotide substitutions per site. The arrows in Panels A and C indicate the expanded sections shown in Panels B and D.
