The viral hemorrhagic (or haemorrhagic) fevers (VHFs) are a diverse group of animal and human illnesses in which fever and hemorrhage are caused by a viral infection. VHFs may be caused by five distinct families of RNA viruses: the families Arenaviridae, Filoviridae, Bunyaviridae, Flaviviridae, and Rhabdoviridae. All types of VHF are characterized by fever and bleeding disorders and all can progress to high fever, shock and death in many cases. Some of the VHF agents cause relatively mild illnesses, such as the Scandinavian nephropathia epidemica (a Hantavirus), while others, such as Ebola virus, can cause severe, life-threatening disease.
Signs and symptoms of VHFs include (by definition) fever and increased susceptibility to bleeding (bleeding diathesis). Manifestations of VHF often also include flushing of the face and chest, small red or purple spots (petechiae), bleeding, swelling caused by edema, low blood pressure (hypotension), and shock. Malaise, muscle pain, headache, vomiting, and diarrhea occur frequently. The severity of symptoms varies with the type of virus. The “VHF syndrome” (capillary leak, bleeding diathesis, and circulatory compromise leading to shock) appears in a majority of people with filovirus hemorrhagic fevers (e.g., Ebola and Marburg virus), Crimean–Congo hemorrhagic fever (CCHF), and the South American hemorrhagic fevers caused by arenaviruses, but only in a small minority of patients with dengue, Rift Valley fever, and Lassa fever.

http://www.bt.cdc.gov/training/historyofbt/ These videos describe the Category A diseases: smallpox, anthrax, botulism, plague, tularemia, and viral hemorrhagic fevers. If these germs were used to intentionally infect people, they would cause the most illness and death. Watch these videos to learn how some of these agents have been or can be used as bioterrorist weapons. Note: Parts of this video were adapted from "Biological Warfare and Terrorism: The Military and Public Health Response," co-produced by the United States Army Medical Research Institute of Infectious Diseases (USAMRIID), the Food and Drug Administration (FDA), and the Centers for Disease Control and Prevention (CDC), 1999.

These include the Ebola and Marburg, Lassa fever, and yellow fever viruses. VHFs have common features: they affect many organs, they damage the blood vessels, and they affect the body's ability to regulate itself. Some VHFs cause mild disease, but some, like Ebola or Marburg, cause severe disease and death. VHFs are found around the world. Specific diseases are usually limited to areas where the animals that carry them live. For example, Lassa fever is limited to rural areas of West Africa where rats and mice carry the virus. The risk for travelers is low, but you should avoid visit...
Ebola hemorrhagic fever (Ebola HF) is one of numerous Viral Hemorrhagic Fevers. It is a severe, often fatal disease in humans and nonhuman primates (such as monkeys, gorillas, and chimpanzees). Ebola HF is caused by infection with a virus of the family Filoviridae, genus Ebolavirus. When infection occurs, symptoms usually begin abruptly. The first Ebolavirus species was discovered in 1976 in what is now the Democratic Republic of the Congo near the Ebola River. Since then, outbreaks have appeared sporadically.

FIRST there was Zika, and now it's Crimean-Congo hemorrhagic fever - but how much do you know about the disease sweeping across Europe? Crimean-Congo haemorrhagic fever (CCHF) is a virus primarily transmitted to people from ticks and animals. While it might not be a commonly-discussed disease, CCHF outbreaks - which causes severe viral haemorrhagic fever outbreaks - have a fatality rate of up to 40 per cent, according to the World Health Organisation. Worryingly the virus is primarily transmitted to people from ticks and livestock animals - but human-to-human transmission can occur after close contact with the blood, secretions, organs or other bodily fluids of infected persons. There is no vaccine available for either people or animals. The panic around CCHF is spreading fast after ...

The Molecular Toolkit of Viral Hemorrhagic Fevers September 12, 2014, 11 a.m. to noon Erica Ollmann Saphire, PhD, Professor, Department of Immunology and Microbial Science, The Scripps Institute, San Diego, California Viruses must achieve a number of functions in their lifecycles, often using compact genomes. Dr. Ollmann Saphire will describe her laboratory's discovery that Ebola virus extends the functional complexity of its seven-gene genome by rearranging at least one of its transcribed polypeptides into different structures, with each distinct protein structure conferring a separate and essential function in the virus lifecycle.
