Crimean–Congo hemorrhagic fever

Crimean–Congo hemorrhagic fever (CCHF) is a widespread tick-borne viral disease that is endemic in Africa, the Balkans, the Middle East and Asia. The virus is a member of the Bunyaviridae family of RNA viruses. It is a zoonotic disease carried by several domestic and wild animals. While clinical disease is rare in infected animals, it is severe in infected humans, with a mortality rate of 10-40%. Outbreaks of illness are usually attributable to Hyalomma tick bites or contact with infected animals or people.
