Comparison Of The Ebola Virus

The pathogen infects many cell types, including monocytes, macrophages, dendritic cells, endothelial cells, fibroblasts, hepatocytes, adrenal cortical cells, and epithelial cells. Because of the difficulty of performing clinical studies under outbreak conditions, almost all data on the pathogenesis of Ebola virus diseases have been obtained from laboratory experiments employing mice, guinea pigs, and a variety of nonhuman primates. Patients with Ebola virus disease typically have an abrupt onset of symptoms 8 to 10 days after exposure (range 2 to 21 days). The incubation period for the individual patient depends, in part, upon the type of exposure. Scientist follow guidelines recommended from the United States Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) for the management of patients who are known or suspected to be infected with Ebola virus. These recommendations include isolation of hospitalized patients with known or suspected Ebola virus disease and correct use and removal of recommended personal protective equipment. These patients are highly contaminated if it is true that they have the virus. If you do not follow all rules and guidelines for the safety of your immune system and body, it is possible you can become infected with the Ebola virus as well. (Up 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 (Bundibugyo ebolavirus). The fifth, Reston virus (Reston ebolavirus), has caused disease in nonhuman primates, but not in humans. Ebola has spread between countries starting in Guinea then spreading across land borders to Sierra Leone and Liberia, Nigeria, USA, Senegal and Mali. Ebola has been presented for more than 35 years; however, the largest outbreak began in West Africa in March 2014. Ebola was previously reported in: Nigeria, Senegal, Spain, United States, Mali, and United Kingdom. However, there are no current cases of Ebola in these countries. There were four people who were diagnosed with Ebola in the United States. The two brought ebola into the country while the other two contracted the disease after caring for an Ebola patient in the United States. One man however died from the disease and the other three recovered and are now free of Ebola. Most of these cases were due to people traveling from a country where ebola was present. This outbreak cause severe and

The first outbreak of Ebola happened in 1976 in Zaire, Africa, from which it got its name. It is believed that the eating of fruit bats and primates is where Ebola first exposed itself in humans. People didn’t know what to think. Scientist began doing a lot of research and breaking the cells down that made up this deadly virus. They discovered that the Ebola virus is a member of the negative strand of RNA viruses known as filoviruses. (Facts behind the Virus 2). There are four different strains of Ebola which are Zaire, Sudan, Tai, and Reston. (Farmer 1). They are alike in many different ways but also have their share of differences. Reston ebolavirus is the only one that isn’t pathogenic to humans. Whenever the scientists magnified the virus, they discovered that it resembles long filaments and are threadlike in the shape of a “U”. The virus has seven gene codes for nucleoprotein, glycoprotein, virion protein, VP30, VP35, VP45, and RNA-dependent RNA polymerase (Mestrovic

The Ebola virus is a virus that has been transmitted throughout Western and Central Africa throughout the past forty years. The virus looks like a long, tube-shaped cell that often tangles over itself; it is about 80 nm in diameter and can grow up to 14,000 nm long (TKH Virology Notes Ebola, n.d.). The Ebola virus was first discovered in Sudan, near a river by the same name. The virus was first discovered in 1976, and is still around today. The ebola virus is in the Filoviridae family and the Ebolavirus genus. There are five known strains of the Ebola virus, they are Tai Forest ebolavirus, Reston ebolavirus, Bundibugyo ebolavirus, Sudan ebolavirus and Zaire ebolavirus (Ebola virus disease, n.d.). The Ebola virus is believed to have started

Ebola virus strikes fear into the hearts of many. Incidentally, this fear seems to be most prominent in certain subsets of the population, mainly manifesting in those living in the periphery or who are impoverished. Often the hardest hit areas are peripheral nations hampered by political turmoil, weak health systems, and who are lacking in human and infrastructural resources.

The Ebola virus (EBOV) is very pathogenic, and it belongs to the genus Ebolavirus within the family of Filoviridae. The virus can cause several syndromes between human and non-human primates. This syndrome includes a hemorrhagic fever. In fact, there is a recent epidemic of EBOV in West Africa that has increased the morbidity and mortality rate of the infection to a higher percentage, but there are surges in developing their health care system to combat the infection and to control the future incidences. West Africa nations that are affected by the Ebola virus has trained healthcare workers about safety methods in handling outbreaks and has given early prophylactic treatment to reduce the dose of the virulent. However, there are two types

The Ebola virus epidemic has been one of the most significant outbreaks in 2014. Ebola has caught the attention of many, for the infection is life-threatening. Obtaining knowledge about the disease is imperative. There are numerous symptoms, risks, material on the subject and ways to prevent Ebola. The malignant virus affects society greatly, yet there are various precautions that can be taken to secure yourself.

The Ebola is a virus, an infective agent which typically consists of a protein coat that contains nucleic acid, and multiples within a host’s living cells. A Virus cannot be seen by a light microscopy due to its small size. The Ebola virus is a member of the Flioviridae family, which contain single, linear, negative-sense ssRNA (ss meaning single strand) genomes that house the cells genetic material. The tubular Ebola virions are normally 80 nm in diameter and 800 nm long. In the center is the necleocapsid, a capsid that holds all of the cell’s nucleic acid, which in this case is a spiral ssRNA genome. Each genome has a length of around 19kb, and codes for eight proteins, seven structural and one non-structural. The nucleocapsid is throughout

Ebola is introduced into the human population through close contact with blood, organs and other fluids of infected animals.

The symptoms of Ebola are a fever, headache, joint and muscle aches, vomiting, stomach pain, sore throat, diarrhea, weakness and occasionally read eyes, rashes, hiccups, and internal and external bleeding and since these symptoms are not specific to Ebola, it is difficult to clinically diagnose and can often be confused with other viruses. The ELISA testing, short for enzyme-linked immunosorbent assay, and virus isolation are a couple of examples of the types of laboratory testing that can be done to diagnose and Ebola patient. Because of how easily it can be transmitted, it is extremely difficult to treat and there is no approved, official treatment. As of now, there is not standard treatment but usually the patients are given fluids and oxygen, have their blood pressure monitored and other necessary treatment. To prevent transmission and spreading the virus, the doctors use extreme caution and wear head to toe protective gear and isolate the patient. Even though the Ebola virus is common in Africa, there has been no known outbreak in the United States. Another difficulty facing scientists and the treatment for Ebola is that the natural reservoir for the virus unknown. The natural reservoir of a virus is it’s long term host of the

Before getting into the life cycle of Ebola there are some things that must be clarified first. Ebola multiplies very rapidly and powerfully and within no time the infected cell becomes enclosed with crystal like blocks or virus particles. These virus particles are already getting ready to replicate. The crystal blocks form at the centre of the cell and begin to grow outwards, and migrate to the cell wall. Once reaching the cell wall, the blocks dissolve into hundred of individual virus particles. The Ebola pieces then creep into the bloodstream of the host and the virus keeps attaching itself to cells everywhere. Here the procedure of replication is then repeated until the tissue becomes saturated with virus crystal blocks. (Garrett 156)

Ebola virus disease (EBV), or just Ebola, is an acute, often fatal illness, with a case fatality rate of up to 90%. It is one of a number of haemorrhagic fever diseases. Ebola is a single-stranded RNA virus with an unusual, variable-length, branched morphology. The helical capsid is enclosed inside a membrane.. It is one of the world’s most virulent diseases. The Ebola virus is a member of the Filoviridae family. There are 5 known subtypes of Ebola. The infection is transmitted by direct contact with the blood, body fluids and tissues of infected animals or people. The current hypothesis is that fruit bats are the original host of the virus. Ebola was introduced into the human population through close contact with the blood, secretions,

The highly dangerous virus- Ebola, causes high fever and death of 90% patients within days. Ebola virus and marburvirus are consider to be the most deadly human pathogens that cause severe fever syndrome in both humans and non human parasites. The virus is further divided into 5 species with different pathogenicities.

What is Ebola hemorrhagic fever? Ebola hemorrhagic fever (Ebola HF) is a severe, often-fatal disease in humans and nonhuman primates (monkeys, gorillas, 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. There are five identified subtypes of Ebola virus. Four of the five have caused disease in humans: Ebola-Zaire, Ebola-Sudan, Ebola-Ivory Coast and Ebola-Bundibugyo. The fifth, Ebola-Reston, has caused disease in nonhuman primates, but not in humans.

Ebola hemorrhagic fever is a severe and often deadly illness named after a river in the Democratic Republic of Congo (formerly Zaïre) where it was first identified 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 first came into the limelight in 1976 in Zaïre 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 cycles in animals or insects, but regardless of the original source. Person-to-person transmission is the means by which Ebola outbreaks and epidemics progress.
