The Ebola Virus Essay, Research Paper


Life


is a biological internet in which viruses travel like


messages, moving at high speed from node to


node and from city to city. They are diverse and


wild spread in every plane on the surface of the


earth. Ironically, such invisible creatures have a


substantially enormous effects on human life and


health. In most cases, Viruses are harmful and


sometimes deadly. One of these deadly viruses is


the Ebola virus, a highly contagious, deadly and


mysterious microbe, known to be the most lethal


virus known to human kind that have caused many


devastation. The mere essence of their existence is


not to cause harm, they are living organisms who


want to reproduce and spread with the help of a


host. The Ebola virus, like most viruses, consists


of a shell of proteins surrounding genetic material,


like RNA and DNA. Once inside the cell, the


virus gets hold to the host cell and the virus may


enter the cell as it injects its genetic material into


the host cell. The virus then uses the host cell’s


machinery to replicate themselves and make new


copies of itself. Each new copy of the virus directs


the host cell to make it a protein shell. The new


viruses leave the host cell to other cells and repeat


the same process over and over again. Although


man is not Ebola’s natural host, the virus infects


people, and the adventure is suicidal as the


infected victims struggle with the symptoms The


infected victim staggers, disoriented and


exhausted, and collapses in a fever, which is


known as the Haemorrhagic fever. The fever is


characterized by weakness, muscle pain,


headache and sore throat. The victim’s eyes turn


bright red, and starts vomiting blood. The tongue


peels, and the heart muscle becomes soft.


Scientists believe that when the victim get in


contact with the virus, the virus first triggers a


combination of blood clots and hemorrhages. The


patient’s bloodstream throws clots, and the clots


lodge everywhere, especially in the spleen, liver,


and brain, then it settle in the victim throat.


Bleeding involves the nose, abdomen, and


pericardium. Capillary leakage appears to lead to


loss of interavascular volume leading the patient to


fall in a shock and acute respiratory disorder


leaving the patient desperately trying to gasp their


breath. The virus kills its victims so quickly, before


it even can infect others. The incubation period for


the Ebola virus ranges from 2 to 21 days,


depending upon the method of infection. The


Ebola virus can be diagnosed with laboratory


testing of blood specimens under maximum


containment conditions as the high risk of infection


to those handling infected blood remains a


nightmare to them. Infection of this deadly virus


occurs through the blood and is replicated in


organs like the Liver, lymphatic organs, and the


kidneys. However, it is spread through close


personal contact with the infected person who is


very ill with the disease. Normally, the wild spread


of Ebola virus takes place among hospital care


workers or family members who were aiding an


infected person. Ebola can spread by the reuse of


hypodermic needles, w

hich occurs frequently in


underdeveloped countries like Zaire and Sudan,


but it is unlikely to become infected by close


contact with persons infected who show no


symptoms. Three outbreaks of Ebola hemorrhagic


fever among people had been reported. The first


two outbreaks were in 1976: one in Zaire and one


in western Sudan. These were large outbreaks,


resulting in more than 550 cases and 340 deaths.


The third outbreak, in 1979 in Sudan, was smaller,


with 34 cases and 22 fatalities. During each of


these outbreaks, a majority of cases occurred in


hospital settings under the challenging conditions of


the developing world. These conditions, including


lack of healthy medical supplies and the reuse of


the same needles and syringes, played a major


role in the spread of disease. Through isolation of


sick persons in a place requiring the wearing of


mask, gown and gloves careful sterilization of


needles and syringes and proper disposal of waste


and corpses. Causing death in 85% of all ill cases.


More than 5,000 people have been infected


worldwide. Victims go mad, endure unbelievable


pain, with blood leaking from every orifice. Yet no


one knows where the virus comes from, or when it


will strike next. Although humans have gotten


Ebola from infected monkeys, these primates are


considered unlikely long-term hosts because the


virus kills them. Until now, scientists do not know


where does the virus lives in nature, or who is the


original host. But they hypothetically believe that it


came from the forest. The gruesome mystery of


who’s the original host of the Ebola virus remains


unanswered. While the monkey remain the main


suspect, efforts have been done to minimize the


spreading of the disease. "One of deadliest


diseases known has emerged from the forests of


Africa" said Purvis, an author of a published article


in the Time magazine. Purvis discussed the


scientists suspensions about the original host of this


lethal virus in his article. He said that the scientists


had suspected that the disease which killed 245 in


the Zairian town of Kikwit, was transmitted to


humans from Chimpanzees or eating dead


monkeys. Colobus monkeys, for example, can


transmit the virus to chimpanzees, which hunt


them, and people get the virus after eating a dead


chimp, and that where the theory that chimp carry


the virus came from Elizabeth Neus, an Idaho


statesman author, agrees with Purvis that


chimpanzees might be the real host for the virus.


Purvis and Neus both agree that the theory looks


pretty solid since the last out Break of the Ebola


virus. However, this theory contradicts what Steve


Sternberg, who scientifically proved, that bats only


the bats proved capable of carrying Ebola. bats


could be the animal host that scientist have


searched for ever since Ebola first emerged in


Zaire. Researchers have been greatly slowed by


extreme of pathogens of the virus. Weather Ebola


can be cured or not? Will be forever a mystery, till


scientists can slow the rapid growth of those


viruses. Slow enough to give man kind a fighting


chance to their existence, and slow than messages


that is transmitted by the internet
