Essay about Ebola Hemorrhagic Fever - 1267 Words

Ebola Hemorrhagic Fever Ebola hemorrhagic fever (Ebola HF) is a severe, often-fatal disease in humans and nonhuman primates (monkeys and chimpanzees) that has appeared sporadically since its initial recognition in 1976. The disease is caused by infection with Ebola virus, named after a river in the Democratic Republic of the Congo (formerly Zaire) in Africa, where it was first recognized. The virus is one of two members of a family of RNA viruses called the Filoviridae. Three of the four subtypes of Ebola virus identified so far have caused disease in humans: Ebola-Zaire, Ebola-Sudan, and Ebola-Ivory Coast. The fourth, Ebola-Reston, has caused disease in nonhuman primates, but not in humans. Where is Ebola virus†¦show more content†¦Ebola HF typically appears in sporadic outbreaks, usually spread within a health-care setting (a situation known as amplification). It is likely that sporadic, isolated cases occur as well, but go unrecognized. How is Ebola virus spread? Infection with Ebola virus in humans is incidental -- humans do not carry the virus. Because the natural reservoir of the virus is unknown, the manner in which the virus first appears in a human at the start of an outbreak has not been determined. However, researchers have hypothesized that the first patient becomes infected through contact with an infected animal. After the first case-patient in an outbreak setting (often called the index case) is infected, the virus can be transmitted in several ways. People can be exposed to Ebola virus from direct contact with the blood and/or secretions of an infected person. This is why the virus has often been spread through the families and friends of infected persons: in the course of feeding, holding, or otherwise caring for them, family members and friends would come into close contact with such secretions. People can also be exposed to Ebola virus through contact with objects, such as needles, that have been contaminated withShow MoreRela tedThe Epidemic Of Ebola Hemorrhagic Fever1893 Words   |  8 Pages â€Æ' Introduction Ebola hemorrhagic fever is a severe and often deadly illness named after a river in the Democratic Republic of Congo (formerly Zaà ¯re) where it was ï ¬ rst identiï ¬ ed in 1976 with a high case fatality rate lying between 50 and 90%. Outbreaks between 1972 and 2007 are shown in Table 1. The disease ï ¬ rst came into the limelight in 1976 in Zaà ¯re and Sudan in 1976 [17]. Its origin is still unknown and it is widely believed that Ebola virus is transmitted to humans from discrete life cyclesRead MoreIs Ebola Hemorrhagic Fever ( Ehv )?1471 Words   |  6 PagesWhat is Ebola Hemorrhagic Fever (EHV)? EHV is a severe and often fatal disease caused by the ebolavirus. It has an incubation period of 2 days to 3 weeks, during which the patient is not contagious. The patient will become contagious when the first symptoms appear, namely fever, sore throat, muscle pain and headaches, followed by vomiting, diarrhea, decreased kidney and liver function, and finally, internal and external bleeding. The virus can be from wild animals, as well as through human to humanRead MoreSymptoms And Treatment Of Ebola Hemorrhagic Fever2074 Words   |  9 Pages Ebola Hemorrhagic Fever is caused by a virus found in the family of filoviridae, in genus known as ebolavirus. There are currently four known Ebola virus strands that are deadly to humans. The virus is transmitted through bodily fluids so it can be transferred via mucosal surfaces or abrasions on the skin when being in direct contact to an infected person. It is highly pathogenic and causes death in approx. 50 -90% of all known cases. This laboratory and numerous experiments has shown that antigenRead MoreViral Hemorrhagic Fever and Ebola Virus Species2359 Words   |  10 PagesWhat is Ebola hemorrhagic fever?

Ebola viruses are members of the filovirus family. The Ebola virus causes the infection of this disease. There are four subtypes of the Ebola virus that have occurred in humans: Ebola Sudan, Ebola Zaire, Ebola Ivory Coast, and Ebola Bundibogyo. There was also a case of Ebola that occurred in a non-human in Reston, Virginia. The Zaire virus was the first Ebola virus discovered and it is also consideredRead MoreThe Ebola Virus1631 Words   |  7 PagesThe 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 thatRead MoreEbola Essay851 Words   |  4 PagesEbola Impact on Human Health amp; Hygiene Essay Historically Ebola has had a serious impact on human health and hygiene and still does due to the fact of no vaccine or treatment being discovered, but thanks to improvements in scientific and medical knowledge the virus itself is now controllable. Ebola is the virus Ebolavirus (EBOV), a viral genus, and the disease Ebola hemorrhagic fever (EHF), a viral hemorrhagic fever (VHF).

From the year of 1976 to the present date of 1996, researchers have searched forRead MoreEssay about Bioterrorism - Viral Hemorrhagic Fever2177 Words   |  9 PagesBioterrorism - Viral Hemorrhagic Fever Abstract Viral hemorrhagic fever is one of the most feared diseases of todays time. Although most people have heard of anthrax, smallpox and the plague, viral hemorrhagic fever has become a potent weapon used for bioterrorism, silently killing its victims and instilling fear in the rest of the population. Viral hemorrhagic fever can be divided into 4 families. Although each family of viral hemorrhagic fever may have some of its own unique characteristicsRead MoreEbola Virus Disease ( Evd )1018 Words   |  5 PagesEbola virus disease (EVD) is a severe, often fatal illness in humans. EVD outbreaks have a case fatality rate of up to 90%. Ebola first appeared on July 27, 1976, the very first person to contract the Ebola virus began to show symptoms. Ten days later he was dead. The latter was in a village situated near the Ebola River, from which the disease takes its name., with a total of 602 reported cases and 431 deaths. The first victim to contract Ebola was a cotton factory worker from Nza ra, Sudan. Soon
