For most viral hemorrhagic fevers caused by arenaviruses, no prophylactic vaccine is available yet. Only one therapeutic treatment is currently available and should be administered at the early stages of the infection. This is particularly problematic as these diseases are difficult to diagnose and cure. Lassa fever is the most important pathology caused by arenaviruses, including millions of people at risk in West Africa. For decades, promising studies focusing on the development of vaccine candidates targeting Lassa virus have been published, but no vaccine candidate had reached the clinical phase. The second arenavirus in terms of number of human infections is the Junín virus in Argentina. The Junín infected case number has drastically decreased since the use of the Candid #1 vaccine. This review summarizes past and present experimental studies regarding treatments against arenaviruses responsible for human hemorrhagic fevers from a prophylactic and therapeutic point of view. It also discusses future breakthroughs to get available and effective treatments.
