Viral haemorrhagic fevers (VHFs) refer to a group of febrile illnesses, often accompanied by multiple organ dysfunction and haemorrhagic manifestations due to increased vascular permeability. They are caused mainly by RNA viruses belonging to four distinct families: Arenaviridae, Bunyaviridae, Filoviridae, and Flaviviridae. Some of these viruses have the potential for person-to-person transmission, and nosocomial infections and outbreaks are often observed. Attention has to be paid for imported cases in order to prevent further transmission. Ticks, mosquitoes, rodents, or bats play a significant role in many VHFs, which therefore are geographically restricted to areas where the related reservoirs, hosts, and vectors live. As in most viral infections, laboratory diagnosis is based on molecular and serologic methods, while isolation of the virus should be attempted only in high containment biosafety laboratories. The case fatality rate of VHFs is usually high, while no specific antiviral drugs or vaccines are currently available. Supportive treatment is essential. Strict isolation and barrier nursing of the patients are needed for specific VHFs. Prevention measures depend on the transmission modes of the virus. Report to public health authorities and early warning is important.
