Without treatment, the infection takes a lethal course in 40% of cases. In 25%, massive internal bleeding occurs. Lassa fever is a viral hemorrhagic fever caused by Lassa virus (Lassa mammarenavirus), a negative-sense single stranded RNA virus of the Arenaviridae family. In most cases Lassa virus infection is asymptomatic (presenting no symptom). Objectives. To determine factors associated with mortality among confirmed Lassa fever cases.Methods. We reviewed line lists and clinical records of laboratory-confirmed cases of Lassa fever during the 2016 outbreak in Nigeria to determine factors associated with mortality.
