On page 158, Preston writes, “Once the virus enters the cell, it becomes a Trojan horse”. Ebola is described as a very dangerous virus. The scientists try to find an end to this virus but know that it is unstoppable. Allusion is used when describing how Ebola invades the body. The Ebola virus enters the body and kills the host from the inside out.
“The more one contemplates the hot viruses, the less they look like parasites and the more they begin to look like predators” (Preston 136). There is many different viruses around the planet; each spreading and mutating, jumping from species to species, picking out and taking down their prey. Richard Preston identifies viruses as predators in his novel, The Hot Zone, to show just how lethal they really are; the worst being the hot agent Ebola. The Ebola virus is the most dangerous hot agent, with high fatality rates, mutations, and limited survivors. Ebola is one of many hot agents around the world, however it is the deadliest.
Identification would be identifying and treats promptly in order to shorten the time during which they can infect others. Isolation would be isolating the infected persons prevents contact with susceptible persons and stops the spread of the disease. 5) Explain: a) What is the difference between HIV and AIDS? HIV is early stage of the infection. HIV is an RNA virus that belongs to a class of viruses called retroviruses.
The recent outbreak of food poisoning in South Africa that led to several deaths is Listeria(listeriosis). Listeriosis is an infection that is caused by consuming food contaminated by the bacteria Listeria. The infection can cause serious illness in pregnant women, neonates, adults with weakened or compromised immune systems and the elderly, and is capable of causing gastroenteritis in others who have been severely infected. Most people infected show no symptoms, but the elderly and very young are vulnerable. The outbreak would be discussed under the following Causative organism; Listeria monocytogene, is the organism that caused the outbreak.
However, the third stage is the most serious one because it affects the lungs directly. In addition, the patients with active TB have painful symptoms and maybe cannot survive. the main cause of the tuberculosis disease is the transmission of the bacteria. Moreover, the people who have unhealthy immune systems have a big chance to acquire TB. The Effect of the TB on the body of the patient and the patient's life are so strong and harmful.
Trench fever is carried by both body lice and ticks, but the bacteria it carries is what causes the disease. The bacteria is called Bartonella quintana. It is a highly contagious disease so if a soldier living in a crowded space has trench fever, it will spread to others fairly quickly. The body louse does not live on your body, but usually in the seams of your clothes however, it still sucks your blood. The louse causes itching, but the disease it carries is much worse.
This disease affect to the mammals like; sheep, cow, and deer. The most common form of the human prion disease is sporadic, is also called Gertsmann-Straussler-Scheinker syndrome (GSS), Creutzfeldt-Jakob disease (CJD), fatal familial insomnia (FFI), kuru and variably protease-sensitive prionopathy (VPSPr) (Holman, et al.,2010). All forms of HPD caused under the there principles; acquired, genetic or sporadic. Accuired types of this are scary and hard to catch so its common way is infections. The next type is “Karu”- it can pass one person to another person by cannibalishm, in Papua New Guinea.
Wright 5 Jayla WrightJared DiamondEnglish 428 February 2018 The Epidemic of SmallPox One of the most scariest diseases, if not the scariest disease, was smallpox. Smallpox was a game change in the 1500’s. The smallpox most definitely had one of the biggest impacts on the world. People often say that had it still been occurring it would have wiped out mankind and possibly all mammals, reptiles, amphibians and possibly most birds, and bugs. The cause of the civil war was because of an epidemic of smallpox.
The Biological weapons also affect other living organisms. Types of Biological weapons There are 3 types of Biological agents that can be weaponized, these 5 agents differ in strength and effect. • Bacterial agents: single cell organisms that cause diseases such as tularemia, plague and anthrax –which is considered the deadliest bacterial agents as it can cause death in 24-36 hours and it easily
Japanese encephalitis, West Nile, and yellow fever) to human (Mitchell 1995, Shroyer 1986). All these viruses are very harmful to human and other organisms, they causes several diseases to humans. For instance in 2007 there was an outbreak of chikungunya in Italy, and other cases of dengue viruses were reported in south France and Croatia. The dengue virus is known to have four strains, therefore attacking one strain doesn’t immunize against contracting the other strains, so it become so difficult to treat the diseases caused by this virus. Chikungunya virus causes fever, swelling and redness of joints, severe rheumatic pains and in some cases death; according to research in various lab it has been shown that when a person is repeatedly infected with dengue viruses, this increases the risk of more severe sickness such as DenguhocyndromSS which induces shock as a result of a sharp drop in the volume of blood which might also lead to
What is lupus? According to Mayo Clinic staff lupus is defined as “a chronic inflammatory disease that occurs when the body’s immune system attacks your own tissues and organs. Inflammation caused by lupus can affect many different body systems including your joints, skin, kidneys, blood cells, brain, heart and lungs”(Mayo clinic.org). With lupus your body’s immune system fights off viruses, bacteria, and germs, normally the immune system produces proteins called antibodies that protect the body from these viruses. “Autoimmune means your immune system cannot tell the difference between these foreign invaders and your body’s healthy cells and tissues and creates autoantibodies that attack and destroy healthy cells and tissue.
Many of the symptoms related to this disease are chills, nausea, fever, swollen lymph nodes, headaches and weakness. However, different strains of this plague can produce a variety of symptoms. Anyone who visits Yosemite National Park should be on the lookout for these symptoms for a few weeks after visiting. If this plague is not treated immediately, it can be fatal. Through much scientific research, a bacteria called Yersinia Pestis was discovered.
When this gene has been mutated, it is unable to perform effectively, leaving exocrine based organs unprotected. (Human Genome Cystic Fibrosis) The symptoms of cystic fibrosis can vary from case to case, but the most common symptoms include male infertility, persistent coughing, salty-tasting skin, frequent lung infections such as penuomonia and bronchitis, shortness of breath, wheezing, weight-loss, and difficult bowel movements. Often times the acronym, CF, to represent cystic fibrosis. People with cystic fibrosis make it a very big priority to have minimal contact with
