Description and characterization of a novel live-attenuated tri-segmented Machupo virus in Guinea pigs [PDF]
Background Machupo virus (MACV) is a member of the Mammarenavirus genus, Arenaviridae family and is the etiologic agent of Bolivian hemorrhagic fever, which causes small outbreaks or sporadic cases. Several other arenaviruses in South America Junín virus

MACV infections are a significant public health concern and lead to high case fatality rates. No specific treatment or vaccine for MACV infections exist. However, cases of Junin virus infection, a related virus, can be treated with convalescent-phase serum. This indicates that a MAb-based therapy for MACV could be effective.

Drug discovery technologies and strategies for Machupo virus and other New World arenaviruses [PDF]
Seven arenaviruses cause viral hemorrhagic fever in humans: the Old World arenaviruses Lassa and Lujo, and the New World Clade B arenaviruses Machupo (MACV), Junín (JUNV), Guanarito (GTOV), Sabiá (SABV), and Chapare (CHPV). All of these viruses are Risk Group 4 biosafety pathogens. MACV causes human disease outbreak with high case-fatality rates.
