Lassa fever is an acute and often fatal viral disease, with fever, occurring mainly in West Africa. It is usually acquired from infected rats. The illness was discovered in 1969 when two missionary nurses died in Nigeria. The virus is named after the town in Nigeria where the first cases occurred. Lassa fever occurs more often in the dry season, rather than in the rainy season.

While most humans are infected either from contact with an infected rat or inhalation of air contaminated with rat excretions, like other hemorrhagic fevers, Lassa fever can be transmitted directly from one human to another.
