Virus
Arenaviruses are enveloped, single-stranded, bisegmented RNA viruses with ambisense genomes. Based on their antigenic properties, arenaviruses have been classified into two major groups: the Old World arena viruses, and the New World arenaviruses. Old World arena viruses include lymphocytic choriomeningitis virus, and Lassa virus. New world arena viruses are further broken down into three clades, A, B, and C. The Guanarito arena virus belongs to clade B and is the cause of VHF. On the biosafety level scale of one to four, with four causing the most risk, the viruses causing hemorrhagic fevers have been assigned a four by the CDC.
