Bioterrorism - Viral Hemorrhagic Fever

Bioterror - viral hemorrhagic fever Summary Viral hemorrhagic fevers are one of the most severe diseases today. Although most people have heard about anthrax, smallpox, plague, viral hemorrhagic feet became a powerful weapon of bioterrorism, quietly killed the victim and brought horror to others. Viral hemorrhagic fevers can be divided into four families. Each viral hemorrhagic fever family may have some unique features, but these four families are quite similar in terms of the high fever and bleeding they normally cause.

Lassa fever or Lassa hemorrhagic fever (LHF) is the acute viral hemorrhagic fever caused by Lassa virus first reported in Lhasa, Borno, Nigeria in 1969. Lassa fever is a member of the Arenavirus family. Like Ebola virus, the clinical case of this disease is more than 10 years old, but it is irrelevant to viral pathogens.

Ebola virus is a new type of viral infection, and viral infections, viruses, viruses, yellow viruses and bovine viruses are viruses that cause viral hemorrhagic fever. All forms of viral hemorrhagic fever begin with fever and muscle pain. These diseases usually last until patients undergo respiratory illness, severe bleeding, kidney dysfunction and shock. The conclusion of viral hemorrhagic fever varies from mild disease to death. (Bib 5, Ebola Paper, 1)

Ebola virus can cause diseases called Ebola hemorrhagic fever, viral hemorrhagic fever, which usually causes. According to the minutes of the 4th National Biosafety Symposium, the clinical definition of viral hemorrhagic fever is as follows. "Viral hemorrhagic fever is an acute infection that begins with the progression to fever, muscle pain, discomfort and failure, showing evidence of vascular dysfunction and increased vascular permeability, involving multiple systems Shock, encephalopathy, extensive bleeding, poor prognosis should be expected. "(4th National 2)

Viral hemorrhagic fevers such as Ebola virus disease, Lassa fever virus, Rift Valley fever, Marburg virus and Bolivian hemorrhagic fevers, etc. can become a pandemic is theoretically very contagious and fatal disease. However, the expansion of these viruses requires intimate contact with the infected vector, and because the vector is brief before death or serious illness, those that diffuse effectively to cause a pandemic The ability is limited. In addition, a short period of time between the onset of a carrier and the onset of symptoms allows medical professionals to quickly isolate the vectors and prevent them from carrying pathogens elsewhere. Genetic variation may occur and may increase the likelihood of extensive harm; therefore, close observation by infectious disease experts is worthwhile
