Known geographic and host ranges of African monkey plasma viruses. (A) Map of Africa showing the sampling locations of monkeys in which simian pegivirus or simian arterivirus infection was identified. In the table, a colored dot indicates that SIV (red), SPgV (green), or a simian arterivirus (blue) infection was detected in that particular primate from that particular location (61–64). NYP, not yet published. (B) Genus-level phylogenetic tree of African OWMs and great apes. Colored dots indicate that SIV (red), GBV-C (green), or SHFV (blue) infection was detected in a primate from that genus. Names in boldface type indicate genera from which we have sampled more than 10 wild primates by unbiased deep sequencing (for a comprehensive list of species naturally infected with SIV, see reference 65).
