Supportive therapy is important in Lujo hemorrhagic fever. This includes:
Treatment of arenavirus hemorrhagic fevers with convalescent plasma therapy reduces mortality significantly and anectodal evidence from the only surviving Lujo patient shows that the antiviral drug ribavirin may hold promise in the treatment of LUHF. Ribavirin has been considered for preventing development of disease in people exposed to other arenaviruses.
The precise mortality of LUHF is unknown, but 4 of 5 described cases were fatal.
Patients who have suffered from other arenaviruses may excrete virus in urine or semen for weeks after recovery. For this reason, these fluids should be monitored for infectivity, since convalescent patients have the potential to infect others (particularly sexual partners) via these fluids.
