According to the World Health Organisation, Lassa fever is an acute viral haemorrhagic illness caused by the Lassa virus, a member of the arenavirus family of viruses and humans usually become infected with the Lassa virus through exposure to food or household items contaminated with urine or faeces of infected Mastomys rats. The disease is endemic in the rodent population in parts of West Africa.  

Lassa fever is known to be endemic in Benin, Ghana, Guinea, Liberia, Mali, Sierra Leone, Togo, and Nigeria, but probably exists in other West African countries as well.  

“Person-to-person infections and laboratory transmission can also occur, particularly in health care settings in the absence of adequate infection prevention and control measures.

“Diagnosis and prompt treatment are essential. The overall case-fatality rate is one percent. Among patients who are hospitalised with severe clinical presentation of Lassa fever, case fatality is estimated at around 15 percent. Early supportive care with rehydration and symptomatic treatment improves survival. 

“About 80 percent of people who become infected with Lassa virus have no symptoms. one in five infections result in severe disease, where the virus affects several organs such as the liver, spleen, and kidneys,” WHO said.
