  ICS Ltd. Viral Haemorrhagic Fever - Introduction
Haemorrhagic diseases that are theoretically capable of being transmitted from man to man include Lassa, Marburg, Ebola and Congo-Crimean haemorrhagic fever.
In Africa, transmission of VHF has been associated with the reuse of unsterilised needles and the provision of patient care, without appropriate barrier precautions to prevent exposure to virus-containing blood and other body fluids, such as vomitus, urine and stool.
Congo-Crimean haemorrhagic fever arises from a family of similar viruses that are widespread in Africa, Western Asia and in the USSR.

  Viral Hemorrhagic Fevers | CDC Special Pathogens Branch
Viral hemorrhagic fevers (VHFs) refer to a group of illnesses that are caused by several distinct families of viruses.
In general, the term "viral hemorrhagic fever" is used to describe a severe multisystem syndrome (multisystem in that multiple organ systems in the body are affected).
VHFs are caused by viruses of four distinct families: arenaviruses, filoviruses, bunyaviruses, and flaviviruses.

 VIRAL AGENTS
Viral Haemorrhagic Fevers are transmitted to humans by arthropod vectors, such as mosquitoes, or by contact with infected animal reservoirs.
This is an acute viral infectious disease that is transmitted by mosquitoes’ bites.
Yellow fever is characterised by a sudden onset of symptoms including high fever and chills, severe headache, muscle aches, conjunctival injection, nausea, vomiting and diarrhoea.

 NATIONAL PROGRAMMES FOR DISEASE PREVENTION AND CONTROL
VHF should be suspected in any patient presenting with “a severe febrile illness and evidence of vascular involvement” (sub-normal blood pressure, petechiae, easy bleeding and long dependent oedema).
Diagnosis is confirmed through demonstration of viral antigens in the sera of patients in the acute phase of the disease.
CCHF is an acute viral haemorrhagic fever characterized by extensive ecchymoses, mucosal, gastrointestinal and genito-urinary bleeding and hepatic dysfunction associated with a 15-40% mortality rate.

In 1967, a unique viral haemorrhagic fever appeared in laboratory workers in Marburg in West Germany, which was traced to contact with the blood and tissues of a group of African Green or vervet monkeys imported from Uganda.
The onset of illness is sudden and marked by fever, chills, headache, myalgia, and anorexia.

Viral haemorrhagic fever is the collective name for a group of illnesses caused by different viruses but which have the common features of high fever and disturbance of the normal blood-clotting mechanisms.
Of the many kinds of haemorrhagic fever, only yellow fever has a preventative vaccination, and none is directly treatable other than symptom relief and supportive care for the body’s normal functions.
Viral haemorrhagic fevers rarely cause major epidemics (with the exception of yellow fever) but sporadic local outbreaks occur with devastating effect.

Patients with suspected VHF who have a prominent cough, vomiting, diarrhoea, or haemorrhage should be placed in a negative-pressure room in order to prevent possible exposure to airborne particles.
