| Lassa f. |
an acute febrile disease caused by an arenavirus (Lassa virus), endemic throughout West Africa and spread by contact with the multimammate mouse, which sheds the virus in its urine, or by interpersonal contact; most infections are subclinical or mild, although severe cases resulting in death occur. Symptoms include fever of insidious onset, headache, dry cough, back pain, vomiting, diarrhea, pharyngitis, facial edema, and occasionally a maculopapular rash; in severe cases there is a sudden drop in blood pressure on the seventh day, with death resulting from shock, hypotension, peripheral vasoconstriction, hypovolemia, and anuria. Sensorineural deafness, which may be permanent, sometimes results.
