Lassa Fever
Prognosis for Lassa Fever
Recovery or death usually occurs 7 to 31 days (average 12 to 15 days) after symptoms begin. Approximately 15 to 20% of patients hospitalized for severe Lassa fever die from the illness (Centers for Disease Control and Prevention [CDC]:Lassa Fever Signs and Symptoms). Disease is severe during pregnancy, especially during the 3rd trimester. Most infected pregnant women lose the fetus (CDC:Lassa Fever Signs and Symptoms).
