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 two, in Zaire and in western Sudan, were large outbreaks that resulted in more than 550 cases and 340 deaths. The third outbreak, in Sudan, was smaller, with 34 cases and 22 deaths” (2). The most recent outbreak was reported only eight years ago in Kikwit, a surrounding area of Bandundu Province, and 316 deaths were reported. In most of these cases the outbreaks were reported in health-care settings, a situation known as amplification, and were caused by poor nursing techniques and usage of unsanitary hospital supplies.
This highly infectious disease is caused by the infection by the Ebola virus itself. This Ebola virus, named after a river in the Democratic Republic of the Congo, is one of two members of a family of RNA viruses known as Filoviridae (http://web.uct.ac.za/microbiology/ebola/ebomurph.gif). Even though the exact origin of the virus is unknown, evidence tells researchers that the virus is animal borne and is usually maintained in an animal host. Evidence also informs researchers that the animal host is native to Africa. Because the origin of the virus is unknown, the carrier state of the virus is also unknown. Therefore the process in which a human is infected with Ebola virus is also undetermined.
An infected human patient can transmit the virus in several ways, by direct contact with blood or bodily secretions of an infected patient, and by contact with objects such as needles used to treat an infected patient. A transfer of the virus from the host to healthy patients is a process known as nosocomial transmission, and occurs frequently through out the period of the outbreak itself.
The symptoms of the Ebola hemorrhagic fever are very grotesque and show up soon after the person is infected. Within two to twenty one days, the infected person will have a sudden increase in body temperature, joint and muscle pain, sore throat, weakness, followed by diarrhea, vomiting, and stomach pain. A rash will then appear, followed by red eyes and internal and external bleeding. Even though the symptoms seem unbearable, some infected patients actually survived this fever.
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

trial vaccinations in an effort to combat the Ebola virus, also known as hemorrhagic fever, and prevent further outbreaks from occurring in the future. These trial vaccinations have shown significant promise in developing the appropriate antibodies to two different strains of the Ebola virus. Most importantly, it has shown significant promise in a large group of test subjects in developing the antibodies necessary to protect them from catching the virus, even when the person has been in direct contact
The Ebola Haemorrahagic Fever, or Ebola for short, was first recognized as a virus in 1967. The first breakout that caused the Ebola virus to be recognized was in Zaire with 318 people infected and 280 killed. There are five subtypes of the Ebola virus, but only four of them affect humans. There are the Ebola-Zaire, Ebola-Sudan, Ebola-Ivory Coast and the Ebola-Bundibugyo. The fifth one, the Ebola-Reston, only affects nonhuman primates. The Ebola-Zaire was recognized on August 26, 1976 with a 44 year
The Ebola virus was discovered in 1976. It has four strains, each from a different geographic area, but all give their victims the same painful, often lethal symptoms. The Ebola virus and Marburg virus are the two known members of the Filovirus family. Marburg is a relative of the Ebola virus. The four strains of Ebola are Ebola Zaire, Ebola Sudan, Ebola Reston, and Ebola Tai. Each one is named after the location where it was discovered. These filoviruses cause hemorrhagic fever, which is actually
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 Ebola
spread of the Ebola virus that has infamously swept across the media and the ears of many in recent months, is the response to the drastic sub-Saharan outbreak in three nations: Liberia, Guinea, and Sierra Leone. There have been further cases of contracted patients in neighboring cities and countries, but not near the magnitude of the three countries housing the epicenter. Fear of the deadly virus has plagued the American people since breaking news in August. The danger the virus presents to the
directly affects them. This paper will prove that the Ebola virus is a serious problem facing the world’s population. In the United States today, we are not at risk for being infected; however, it is better to be prepared for the worst than to be caught off guard. AIDS was the first of these African viruses to escape the wilds of the Third World and harm others in the world. AIDS was ignored for too long before it began its' global rampage. Ebola, which was first encountered by humans in 1976, has
Ebola is a member of the virus family Filoviridae, causes hemorrhagic fever, which is serious illness in humans and animals. Ebola virus disease is extremely contagious, with mortality rate is 92%. It is transmitted to human from wild animals (chimpanzees, gorillas, monkeys) or from human through liquid body substance like blood, slaver, urine, etc. of a person who is infected with Ebola, except water and air. Ebola virus is found in various countries in Africa. It was first discovered in 1976, during
viruses that can kills up to 90% of its victims. Most of the information known in the world today has been compiled in this article. Ebola is a filovirus of which there are 4 known strains: Marburg, Ebola Sudan, Ebola Zaire, and Ebola Reston. The origins of these viruses come from all around the world, however all of them are lethal. Marburg, the first and simplest of the Ebola family to be discovered, arose in the old city of Marburg, Germany in 1967, when factory workers at Behring Works, which produced
Ebola Virus – A Bloody Killer The first doctor I saw told that it was malaria. Only in the special unit at the hospital I was diagnosed Ebola. I was isolated with other infected. None of us could sleep – we thought we would not make it to the morning. More and more people were dying and their bodies were wrapped and taken away and everything was happening in front of us. But then I started feeling better, step by step, and all symptoms gradually stopped. This was a powerful feeling when other doctors
Introduction: In 1976, the first epidemic of the Ebola virus was presented. It had been discovered in a city called Sudan and the Democratic Republic of the Congo. Ebola is a highly mortal disease, which means that the release of this disease has risks that affect the health of people and can occur in other states. In addition, there are many people who have died from this virus. Moreover, the Ebola virus is a topic that has reached thousands of people since the virus was detected for the second time in 2014
prepare for global outbreak after Ebola victim was allowed on two planes” - - www.mirror.co.uk Until the global outbreak of the Ebola virus in 2014, I heard of a real-life present-day killer virus. Of course, I learned about the Black Plague that occurred centuries ago killing millions of people. But in the modern day, no. It was horrifying. This paper will explore the origins, types, causes/effects, and what is being done to fight the spread of the Ebola virus – the Black Plague of 2014.
Ebola. The name rings with the fear of a horrible death. The interesting thing is, it's not as bad a what you probably conjured up in your mind when you read "Ebola". The Western news media has significantly hyped up the dangers of the virus. In the US, Ebola is virtually synonymous with death! During the current unprecedented worldwide outbreak there have been about 5,000 deaths due to Ebola. Compare this with Influenza, which causes nearly 20,000 deaths every year! Symptoms of Ebola include
fast approaching and so are cases of the Ebola virus. “The Ebola outbreak in West Africa was first reported in March 2014, and has rapidly become the deadliest occurrence of the disease since its discovery in 1976” (“Ebola: Mapping the outbreak”). There is no self administered and/or cost friendly medical tool available that the public can use to expose this Ebola virus. But the future does hold some promising news about ways people can accurately identify Ebola in their own home. Now that litmus paper
