- 51: The Ebola Virus
- The Ebola Virus INTRODUCTION The most deadly killers on this earth are too small to see with the naked eye. These microscopic predators are viruses. In my report, I will answer many basic questions concerning one of the fastest killing viruses, the Ebola virus. Questions such as "How does it infect its victims?", "How are Ebola victims treated?", "How are Ebola outbreaks controlled?" and many others related to this deadly virus. GENERAL INFORMATION The Ebola virus is a member of the negative stranded RNA viruses known as filoviruses. There are four different strains of the Ebola virus - Zaire (EBOZ), Sudan (EBOS), Tai (EBOT) and Reston (EBOR). They are very similar except for small serological differences and gene sequence differences. ...
- 52: Being A Virologist
- ... out, if any, what health career I would choose. My health career is to become a virologist. I came up with this career while I was watching the movie Outbreak. Basically, a virologist works with viruses. They try to find cures or vaccinations for viral threats. Virologists try to create antibodies to fight of viruses. C.D.C. ( Center of Disease Control ) is a large virus bank right here in the U.S.A. A virologist would work in a place like this. There are levels one to five. Level 5 having the most lethal virus. Why would I want to be a virologist? Well the reason for me is, I find viruses fascinating. Trying to find cures for diseases like HIV and the common cold. Yes, the common cold is caused by a virus. And there is no cure for the common cold, just vaccines. I ...
- 53: The Ebola Virus
- ... is capable of doing, how Ebola victims can be properly treated , and by performing prompt action to isolate the virus before it has dispersed. The Ebola virus is a member of a family of RNA viruses know as filoviruses. Marburg virus and four Ebola viruses: Ebola Zaire, Sudan, Reston and Tai are the five different viruses that have been known to cause disease in humans, while Ebola Reston only causes disease within monkeys. Filoviruses, arenaviruses, flaviruses, and bunyaviruses are the viruses responsible for causing viral hemorrhagic fevers. All forms of ...
- 54: Lassa Fever: An Old World Arenavirus
- ... Arenaviridae. Genus Arenavirus, although being around for about 60 years in the form of lymphocytic choriomeningitis, has recently been brought to the public's attention because of the large number of species known as "emerging viruses" in the genera. The genera consists mostly of new world viruses, among them the Junin, Machupo and Guanarito viruses, which cause, respectively, Argentine, Bolivian and Venezuelan hemorrhagic fevers along with a few other non - pathogenic viruses. These viruses, long hidden in the deepest recesses of rain forests, are making their presence felt as ...
- 55: Aids 3
- ... affected by, but also through transfusion of the blood and its components. And sadly, whenever a mother is infected, the unborn child will almost positively receive the virus before, during, or after the pregnancy. The viruses which cause AIDS, otherwise known as Human Immunodeficiecy Viruses(HIV) were first discovered in 1983 cooperatively by Dr. Robert Gallo of the National Cancer Institute and Dr. Luc Montagnier of the Pasteur Institute in France. Aids is caused mainly by the HIV-1 virus ... are puzzled as to why this dominant HIV-1 virus has 10 different genetic subtypes, some think that it is so the virus will survive no matter what. HIV is part of a group of viruses called retroviruses. This category basically describes how the virus transmits and reproduces itself. Which is to say that upon entering the body the virus attaches itself to a T-4 cell(T-Helper cell), ...
- 56: Bronchitis
- ... overdistention of the tiny air-containing sacs of the lung. The cause of bronchitis are from viral or bacterial infections which spreads to the chest. The body uses defence mechanisms to try to prevent the viruses and bacterias from spreading the infections. Examples of defence mechanisms are sneezing, coughing, etc. There are also white blood cells to help us the fight off the bacterias and viruses. However if new viruses and bacterias enters our body then the white blood cells will have to take some time to recognize the new viruses and bacterias. Fortunately, a different kind of white blood cells try to fight ...
- 57: The Flu
- ... flu shot can cause unpleasant side effects or that it may even cause the flu (Vaccine, 1998). The most serious side effect from the vaccine occurs in people who are allergic to eggs, since the viruses used in the vaccine are grown in hens' eggs (Vaccine, 1998). "For this reason, people who have an allergy to eggs should not receive influenza vaccine" (Vaccine, 1998). Elizabeth H. Winslow reported on a study ... of death by 75% to 80%" (Vaccine, 1998). General Information about the Flu "In the United States, flu season usually occurs from about October through April" (Flu Season, 1998). There are three types of influenza viruses types A and B cause epidemics type C causes either a very mild respiratory illness or no symptoms at all (Influenza, 1998). Type C does not cause epidemics and does not pose the severe public health risk that types A and B do (Influenza, 1998). Influenza viruses continually change over time, usually by mutation. This constant changing enables the virus to evade the immune system of its host, so that people are susceptible to influenza virus infection throughout life. This process ...
- 58: Xenotransplantation
- ... play with Xenotransplantation the first thing that would come to mind would be that animals may harbor diseases that, like the Ebola virus or "mad cow" disease, can harm people. (Scientific American, July 97). New viruses can form when viruses from one species infect another. These new viruses can have properties different from, and more deadly than, the original ones. Xenotransplantations from pigs may be less likely to pose a public health risk, but on the other hand we know less about ...

- 60: Style Critique on The Hot Zone
- ... the known paths of Ebola and Marburg in The Hot Zone. He tells of their discovery, effects, and the outbreaks. Level 4 scientists for the Army, the CDC, and several civilian scientists track down the viruses in order to conduct tests and find the secret hiding place of the viruses. The height of the story occurs when Ebola Zaire is discovered in a monkey house near Washington, D.C. and the Army has to decontaminate the entire facility. Luckily, the airborne strain only affected monkeys and didnt infect humans. Preston concludes with his own trip to Africa to look at a possible reservoir of the viruses. Prestons style is sensational journalism. He uses graphic detail when describing the effects of the viruses to make it sensational. Doctors would be brief and scientific in their reports on the symptoms. Preston ...
