According to the World Health Organisation (WHO), Lassa fever is an acute viral haemorrhagic illness caused by the Lassa virus, a member of the arenavirus family of viruses.
The disease is endemic in the rodent population in parts of West Africa particularly in Benin, Ghana, Guinea, Liberia, Mali, Sierra Leone, Togo, and Nigeria but may exist in other West African countries as well.
Humans usually become infected with the Lassa virus through exposure to food or household items contaminated with urine or faeces of infected Mastomys rats.
