  • Bioterrorism - 1,831 words
    Bioterrorism You wake up early for work and kiss your family goodbye. On your daily transit you see a man drop a glass vial in the subway, but you think nothing of it. Moments later you become a statistic. A statistic of Bioterrorism. The threat of Bioterrorism, long ignored and denied, has heightened over the past years and needs to be publicly addressed. There are three possible solutions to this threat that are within grasp. The first of which would be a nation wide vaccination against all agents that could be used against the American public. Second, we could educate people to more efficiently spot the symptoms of such an act, or to protect themselves from an act that has already taken p ...

  • Ebola Hemoragic Fever - 924 words
    Ebola Hemoragic Fever Viral hemorrhagic fevers are a group of diseases caused by viruses from four families of viruses: filoviruses, arenaviruses, flaviviruses, and bunyaviruses. The usual hosts for most of these viruses are rodents or arthropods (such as ticks and mosquitoes). In some cases, such as Ebola virus, the natural host for the virus is unknown. All forms of viral hemorrhagic fever begin with fever and muscle aches. Depending on the particular virus, the disease can progress until the patient becomes very ill with respiratory problems, severe bleeding, kidney problems, and shock. The severity of viral hemorrhagic fever can range from a mild illness to death. The Ebola virus is a me ...

  • Ebola Virus - 1,092 words
    Ebola Virus In the year 1976, Ebola climbed out of its unknown hiding place, and caused the death of 340 people. Fear gripped the victims faces, and uncertainty tortured their minds. The people of Zaire waited outside clinics, churches and in their homes for a treatment of the horrible disease, but there was no cure. They were forced to watch people die, hoping that they would be saved from the violent death of the Ebola virus. From the year of 1976 to the present date of 1996, researchers have searched for origin and cure of the virus. Scientists have carried out numerous studies and investigations, but no one has been able to find the right explanations. Prevention of a world wide outbreak ...

  • Ebola Virus - 1,889 words
    Ebola Virus In the world today, there are many known deadly viruses, but few present as great a threat as Ebola, the virus that causes Ebola Hemorrhagic Fever. Key factors in understanding Ebola HF include: Its history, plan of attack, and the diagnosis and treatment of the disease. The Ebola virus can, and usually does cause a disease called Ebola hemorrhagic fever, which is a Viral hemorrhagic fever. According to the proceedings of the 4th National Symposium on Biosafety, the clinical definition for Viral hemorrhagic fever is as follows. "Viral hemorrhagic fever is an acute infection that begins with fever, myalgia, malaise and progresses to prostration. It shows evidence of vascular dysre ...

  • Ebola Virus - 1,107 words
    ... ltifactorial nature of viral evolution makes it difficult to predict such events. According to Doolittle, retrovirus evolution is sporadic, with retroviruses evolving at different rates in different situations. For instance, the human endogenous retroviral element is shared with chimpanzees, indicating no change in over 8 million years, whereas strains of HIV have diverged in mere decades. Endogenous retroviruses carried in the germline evolve slowly compared with infective retroviruses. Generation of new viral pathogens is rare, and often possible only because of high mutation rates that permit many neutral mutations to accumulate before selective pressure forces a change. The seeming u ...

  • Ebola: A Harbinger Of The End Of The World - 1,458 words
    Ebola: A Harbinger Of The End Of The World English Honors Rewrite #2 Ebola: A Harbinger of the End of the World? Several years ago, a virus which originated in Africa swept the entire world killing millions. This virus is the commonly known HIV virus, the virus which causes the fatal AIDS disease. In the 1950's after virologists began the classification of viruses, isolated cases of what are called hot viruses began springing up around the world. Most of the deadly viruses were hemorrhagic fever viruses. Some different forms of hemorrhagic viruses are Hantaviruses, Arenaviruses, Flaviviruses, Bunyaviruses, and one of the most dangerous types of viruses, the filovirus. If one of these viruses ...

    Human Disease Research Human Disease IINTRODUCTION Human Disease, in medicine, any harmful change that interferes with the normal appearance, structure, or function of the body or any of its parts. Since time immemorial, disease has played a role in the history of societies. It has affected-and been affected by-economic conditions, wars, and natural disasters. Indeed, the impact of disease can be far greater than better-known calamities. An epidemic of influenza that swept the globe in 1918 killed between 20 million and 40 million people. Within a few months, more than 500,000 Americans died-more than were killed during World War I (1914-1918), World War II (1939-1945), the Korean War (1950- ...

All forms of viral hemorrhagic fever begin with a fever and muscle aches. Depending on the particular virus, the disease can progress until the patient becomes very ill with repiratory problems, severe bleeding internally and externally, kidney problems and shock.

  • Richard Preston - 666 words
    Richard Preston In October of l989, Macaque monkeys, housed at the Reston Primate Quarantine Unit in Reston, Virginia, began dying from a mysterious disease at an alarming rate. The monkeys, imported from the Philippines, were to be sold as laboratory animals. Twenty-nine of a shipment of one hundred died within a month. Dan Dalgard, the veterinarian who cared for the monkeys, feared they were dying from Simian Hemorrhagic Fever, a disease lethal to monkeys but harmless to humans. Dr. Dalgard decided to enlist the aid of the United States Army Medical Research Institute of Infectious Diseases (USAMRIID) to help diagnose the case. On November 28th, Dr. Peter Jahlring of the Institute was in h ...

  • The Ebola Virus - 1,594 words
    The 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 that are know to cause disease in humans. The Ebola virus, which dates back to 1976, has four strains each from a different geographic area, but all give their victims the same painful, often lethal symptoms. The Ebo ...

  • The Ebola Virus - 426 words
    The Ebola Virus By: Wesley Mark Whitworth Ebola is an extremely deadly virus in our society today. Some even claim that is the most deadly ever discovered. Ebola is a member of the filoviruses (a family of RNA-BASED viruses). Filoviruses get their name from their peculiar shape. They appear to be long threads or filaments (henceforth the name filoviruses) *See attached photo. This virus was discovered in 1976 in Zaire, Africa and in Western Sudan, Africa. During the first outbreak there were approximately 550 cases leading to 340 deaths. Three years after the first outbreak, a smaller outbreak took place in Sudan, Africa. This outbreak was much smaller though, with only 34 cases and 22 death ...

  • The Ebola Virus: Investigating A Killer - 1,455 words
    The Ebola Virus: Investigating A Killer The female scientist, fully dressed in a quarantine outfit, anxiously prepared to inject a sedative into the arm of the delirious patient. Although he was being held down by several pairs of arms, he was still putting up a good fight. The needle goes in. He jerks. The needle flicks into the forefinger of the scientist. The scientist stares at her finger in shock and disbelief, and runs away. It would only be a few days now before she would die. Thankfully, this is only a scene out of the 1995 box-office hit, Outbreak (Fig. 3), which was about Americans fighting against the spread of a nationwide epidemic caused by one of the most feared viruses of our ...
