What is Lassa Fever?

Lassa fever is an acute viral hemorrhagic fever caused by Lassa virus transmitted from Mastomys rodents to humans. It is endemic in West Africa.

Transmission occurs through contact with food or items contaminated with rodent feces and urine. It can also be transmitted from patient to patient (especially in hospital settings).

Most cases are mild, but in severe cases, hemorrhagic presentation, liver and kidney failure, and permanent deafness may be seen.

Symptoms

Sore throat and cough
Muscle and joint pain
Abdominal pain, nausea, vomiting, diarrhea
Mucosal hemorrhage (in severe cases)

Risk Factors
