Introduction Ebola hemorrhagic fever or Ebola HF is a dreadful and fatal disease in both humans and nonhuman primates, and is caused by an infection of the Ebola virus. Along with the Marburg virus it is a member of the family Filoviridae. The Filoviridae family is negative-sense, or negative-strand, RNA viruses. Along with three other families of negative ssRNA viruses, Filoviridae is set apart as being a family of viruses containing genomes that are nonsegmented (genomes do not contain segments)
The Ebola Virus Ebola is a virus and part of the negative-stranded RNA family known as filovirus. It was discovered in 1976 in Africa and was named after a river in Zaire. When the virus is looked at under an electron microscope the filoviridae appear as being long, thin and occasionally they have 'branches' sprouting from one place or another. Ebola can also take the form of a 'U' or a 'b'. There are four known strains of the virus; they are Ebola Sudan, Ebola Zaire, Ebola Reston and
The Ebola Virus A virus is an ultramicroscopic infectious organism that, having no independent metabolic activity, can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid, either RNA or DNA, surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The virus provides the genetic code for replication, and the host cell provides the necessary energy and raw materials. There are more than 200 viruses that are know to
Ebola was named for a small river near Maridi, Sudan. Since Ebola first appeared in 1967 there have been over 100 cases of Ebola with more than 50% of the patients dying within days of their acute symptoms. Ebola is classified as a Biosafety level four agent because of its extreme pathogenicity and the lack of a vaccine or antiviral drug. Ebola virus (Zaire ebolavirus); Sudan virus (Sudan ebolavirus); Taï Forest virus (Taï Forest ebolavirus, formerly Côte d’Ivoire ebolavirus); and Bundibugyo virus
infecting fruit bats, the Ebola virus found a mutation allowing it to spread to humans. This virus is an acute and often fatal illness. This virus first erupted in two outbreaks in 1976 (one occurring in Nzara and Sudan, while the other occurred in a village near the Ebola river, where the virus takes its name.) The current outbreak, starting in West Africa with the potential to spread throughout the world, is larger and more complex than previous outbreaks. This virus has caused more deaths than
attention from pathologists. Ebola Hemorrhagic Fever, a disease that affects primarily thirdworld countries. It is well contained within African regions, but there is still potential for it to spread. The U.S.A. hasn’t yet had any citizens affected by the disease, although it could happen. We need to take measures to prevent it, it’s a bloody mess! A virus is a very complicated structure. It is not living, though it possesses some traits of a living cell. A virus is made up of chains of proteins
Ebola or Ebola Hemorrhagic Fever; Etiological agent – Ebola virus. Transmission: Transmitted through direct contact with infected body fluids, skin or mucous membrane contact. (1) Reservoirs: Unknown, but it seems to reside in the rain forests on the African continent and in the Western Pacific. General characteristics: The virus is pleomorphic, appearing as long filamentous forms in a variety of shapes. The virions have a diameter of 80 nm and a length of 970 nm. They are composed
Ebola Hemorrhagic Fever- also known as: Green monkey fever It’s going to be the next AIDS virus. There have been a few epidemics or outbreaks of this virus since it has been discovered. The first appearance of this deadly killer occurred in 1972 when a case surfaced in Tandala, Zaire, although it was not fatal. First actual outbreak of the virus took place in 1976 on Yambukou, Zaire. This original strain is known as Ebola Zaire. A total of 328 people were infected and 280 of those people became
The Ebola Virus is an extremely deadly virus found in Africa. There have been multiple outbreaks across Africa and one in the United States. The Ebola virus basically causes uncontrollable bleeding externally and internally. Then your organs become liquefied. This usually results in death(www.encyclopedia.com). The following report contains info on the characteristics and history of the Ebola Virus. After being infected with the Ebola virus it takes 2-21 days to take effect. It depends if you
I chose to do my report of the Ebola Virus. Ebola hemorrhagic fever, also know as Ebola HF, is not a common disease. However, this disease is severe and often fatal in humans and also primates such as monkeys, gorillas, and chimpanzees. Up until 2014, there were only four reported sporadic outbreaks in humans since Ebola was initially recognized in 1976. The first recorded outbreak of the Zaire string of the Ebola virus was in Zaire in the year 1976. Doctors didn’t know how to treat it, that
