Given the role of HHV-6 in Kaposi's Sarcoma should it be called Kaposi's Sarcoma Virus 1 (KSHV-1) and HHV-8 called KSHV-2?
Human Herpesvirus 6 Activates Lytic Cycle Replication of Kaposi’s Sarcoma-Associated Herpesvirus
"Besides HHV-6, we also found that cytokines such as interferon-γ partially contributed to induction of KSHV replication in the co-culture system. These findings suggest that HHV-6 may participate in KS pathogenesis by promoting KSHV replication and increasing KSHV viral load."
