The Lassa virus, a member of the arenavirus family of viruses, causes Lassa fever, an acute viral hemorrhagic illness, according to the World Health Organization.
The most common way for people to become infected with the Lassa virus is through contact with food or household objects tainted by the faeces or urine of infected Mastomys rats. The disease is endemic and affects rodent populations throughout West Africa.
Lashing fever is endemic in eight West African countries, according to reports: Benin, Ghana, Guinea, Liberia, Mali, Sierra Leone, Togo, and Nigeria.
According to reports, the epidemic in Nigeria is being driven by a lack of awareness, a sanitary environment, and late case presentations.
