Lassa fever is an Acute Viral Haemorrhagic Fever illness which is endemic in West Africa.

The incubation period is 621 days. The onset of LF illness is often gradual, with non-symptoms and commonly presents with fever, general weakness and specific signs at the early onset.

After a few days, headache, sore throat, muscle pain, chest pain, vomiting, diarrhoea and abdominal pain may follow.

Severe cases may progress to show facial swelling, and bleeding tendencies (from the mouth, nose, vagina or gastrointestinal tract), and low blood pressure.

Shock, seizures, disorientation, and coma may be seen in the late stages. Complications include: deafness, transient hair loss and gait disturbance may occur during recovery.

About 80 % of Lassa Fever infections are mild or asymptomatic.

Lassa fever virus is transmitted to humans via contact with food or household items contaminated with the urine, saliva faeces, and blood of the rodent (MultiPersontomammate rat). The disease is endemic in the rodent population in parts of West Africa and the multi as a reservoir for the virus. Lassa fever is known to be mammate rat serve endemic in Benin, Guinea, Liberia, Mali, Sierra Leone and parts of Nigeria, but probably exists in other West African countries as well.
