Lujo hemorrhagic fever (LUHF) is a single-stranded Arenaviridae viral infection. It is caused by the Lujo virus. The little clinical evidence was obtained from a tiny bloodstream infection cluster of hemorrhagic illness in South Africa in 2008. The death rate in the instances was 80% (4/5).
The first patient, whose source of illness remained unclear, infected three healthcare professionals. A fourth health professional who had ribavirin therapy and was the lone survivor developed a tertiary infection. The Lujo virus is the second African hemorrhagic fever infection to be identified. (The Lassa virus was discovered in 1969.)
