Comparative evaluation of the antiviral efficacy of virazole and ribamidil in experimental Lassa fever in monkeys

: Lassa virus administered to monkeys aerogenically induced in these laboratory animals a fatal disease modelling the severe course of human Lassa fever. It was demonstrated experimentally that ribamydil, a Soviet analogue of virasol, as well as foreign commercial virasol was therapeutically effective in experimental Lassa fever in aerogenically infected monkeys.
