ICD-10	A96-A99

Viral hemorrhagic fevers (VHFs) are a group of illnesses that are caused by several distinct families of viruses: Arenavirus, Filoviridae, Bunyaviridae and Flavivirus. Some of these cause relatively mild illnesses, whilst others can cause severe, life-threatening disease. Examples include Lassa fever, Marburg virus, Ebola virus, Bolivian haemorrhagic fever, Korean hemorrhagic fever, Crimean-Congo hemorrhagic fever and Dengue hemorrhagic fever.

The broadspectrum antiviral compound ribavirin does not appear to be active against dengue virus. <ref>PMID 2353804.</ref>
