Lassa fever, endemic to portions of West Africa, is a hemorrhagic fever spread primarily through contact with infected rats. It is named after the town in Nigeria where the first cases originated. A crude estimate of Lassa virus infections per year in West Africa is estimated at 100,000 to 300,000, with approximately 5,000 deaths. Approximately 15%-20% of patients hospitalized for Lassa fever die from the illness. However, overall only about 1% of infections with Lassa virus result in death. (Source: CDC, online. )
