β¦ Synopsis
In order to assess the effect of the antiviral Ribavirin on the course of JunΓn virus infection in Callithrix jacchus, seven inoculated monkeys were treated with 15 mg of the drug, twice a day, starting 6 days after infection when all animals were viremic. The three untreated controls showed typical signs of JunΓn virus infection at 14 days pi and their mean time of death was 18 days. In contrast, no signs of illness were detected in Ribavirin-treated animals until 24 days pi, when marmosets showed signs of neurological involvement: 5 of these animals died (mean day of death: 36) but the two remaining treated monkeys improved and survived infection without sequelae. The comparison of survival rates (0% vs 28%) and the delay of the mean day of death observed indicates that the Ribavirin treatment used has therapeutic effect on JunΓn virus infection in vivo.

The neotropical primate Callithrix jacchus infected with Junin virus presented an acute disease with hematological and neurological manifestations and died 17 to 24 days after infection. This picture is similar to that of human Argentine hemorrhagic fever (AHF). Blood coagulation and complement stud
Administration of cyclophosphamide (CY) to guinea pigs infected with a lethal strain of Junin virus (JV) delayed the time of death, with survival of a small number of animals. Virological studies showed a temporary decrease of virus concentration in blood and viscera shortly after the CY injection.
