Overview

Lassa fever is commonly associated with fever on physical examination at admission. At advanced stages of the disease, physical examination findings are more pertinent and often include unstable vital signs, such as tachycardia or relative bradycardia, hypotension, and tachypnea. Physical examination may also be remarkable for abdominal tenderness and distension and neurological impairment.
