Shannon and Pyle first address the discovery of AIDS and HIV- I. Before the disease was clearly identified, it was misdiagnosed among physicians around the world. Patients were often diagnosed with “’opportunistic’ diseases” liked Kaposi’s Sarcoma (KS) and Pneumocystis Carinii pneumonia (PCP) (p3). Both diseases were extremely rare in the United States, and the sudden rise in people diagnosed alerted physicians there was something else going wrong. Hi...

...pines diagnosed patient with it in 1985. The authors show the disease had a pattern of hitting all major urban areas of each country or continent.
Overall, Gary Shannon and Gerald Pyle cannot conclude without a doubt where and how HIV- I originated from and how it traveled to affect people across the globe. They discuss the setbacks that lead to the disease being misdiagnosed and mistreated along with several other factors influencing the diffusion of the disease. Readers are also provided with several theories (Haiti, Central Africa, Zoonotic disease) and uses substantial evidence to dismiss the Haiti and Zoonotic disease theories and provides almost irrefutable evidence to back up what they believe to be the true theory. Shannon and Pyle acknowledge, though, there is no concrete evidence to make a theory a fact, and the “tragedy of AIDS cannot be minimized” (p19).

- The origin of AIDS and HIV has puzzled scientists ever since the illness first came to light in the early 1980s. The first recognized cases of AIDS occurred in the USA in the early 1980s. The illness was resistant to every treatment. The Human Immunodeficiency Virus (HIV) is a lentivirus and just like any other virus of the same type, it targets the immune system and weakens people 's defense systems such as the adaptive and innate immune responses, against infections. These viruses are also known as retroviruses.... [tags: AIDS, HIV, Immune system, Immunodeficiency]

- Introduction Fick’s Law is used to measure the rate of diffusion. Diffusion is the movement of molecules from a region of high concentration to low concentration (Smith, 2012). Diffusion is highly important to almost every living organism. With the aid of diffusion various substances are able to passively move through an organism (Anderson et al., 2012). This process of transporting materials throughout the body can occur without the organism having to expend much energy (Anderson et al., 2012)....

- Models for diffusion of innovations among potential adopters have been recently used to study the life cycle of new products and forecast first-purchase sales. Those models can be used by managers as decision aids to create and perform strategies to maintain the profitability of new products across their life cycle. Bass (1969) pioneered this research area with a model for diffusions of new products under peer communication via word-of-mouth. This model distinguished two parameters: innovation and imitation....

- Introduction: A virus is an infective agent that typically consists of a nucleic acid molecule in a protein coat. It is too small to be seen by light microscopy and is able to multiply only within the living cells of a host. One virus that has received global attention over the last thirty years or so is the HIV/AIDS virus. This virus attacks the body’s immune system, which in turn stops the body’s ability to be able to fight off illness. Thus, people who contract HIV/AIDS are susceptible to death by sicknesses that a healthy individual is able to recover from easily.... [tags: cell, HIV, immune system, HIV-1, health, treatment]

- History and Introduction: There are different myths and views in relation to the origin of HIV. Some researchers believe that HIV-1 and HIV-2 have originated in non-human primates, particularly from chimpanzee and monkeys, in West-central Africa and were transferred to humans in the early 20th century. (UNAIDS, 2007) Another school-of-thought says that people who went for hunting acquired SIV. After, several individual to individual transmissions of SIV, its mutant form, HIV appeared. Some genetic studies of the virus suggest that the most recent common ancestor of the HIV-1 M group dates back to 1910, linking HIV epidemic to the increasing population of colonial African cities at that tim...

- ... During the first 2 weeks to a month after exposure to the HIV infection, most infected individuals with display symptoms of a severe flu. The symptoms include fever, swollen glands, sore throat, rash, muscle and joint aches and pains, fatigue, and headache. The early period of infection is known as the “acute retroviral syndrome” (Stages, 2013). Once the virus is out of the acute stage it enters into the latency stage where it continues to replicate but no symptoms are shown. As the infection progresses and the immune system becomes seriously damaged then the virus has now developed into AIDS.... [tags: blood, main transmission]

- Scientists have concluded, based on mathematical research, that the virus that lead to the epidemic of AIDS can be traced all the way back to 1930, somewhere around Central Africa. Bette Korber, of the Los Alamos National Laboratory in New Mexico, presented this conclusion at the Conference of Retroviruses. The notion that HIV was introduced in contaminated oral polio vaccines in Africa between the years of 1957 and 1961 has been often debated and challenged. The results presented by Korber, not only refute the before mentioned allegations, but also move us toward finding out where the virus really came from and in which direction it is heading in the future....

- The acquired immunodeficiency syndrome (AIDS) was initially recognized in the first half of the twentieth century and has since become a major worldwide epidemic (“Discovery Health”). Debate about the origin of AIDS has enticed considerable concern and controversy since the advent of the epidemic. It is has been proven that AIDS is caused by the human immunodeficiency virus (HIV) by stimulating the destruction and functional impairment of cells in the immune system, potentially destroying the human body’s ability to fight infection (“CDC”)....

- AIDS Is the message getting through. We already know enough about AIDS to prevent its spread, but ignorance, complacency, fear and bigotry continue to stop many from taking adequate precautions. We know enough about how the infection is transmitted to protect ourselves from it without resorting to such extremes as mandatory testing, enforced quarantine or total celibacy. But too few people are heeding the AIDS message. Perhaps many simply don't like or want to believe what they hear, preferring to think that AIDS "can't happen to them." Experts repeatedly remind us that infective agents do not discriminate, but can infect any and everyone.... [tags: Free AIDS Essays]

- Lab Report #1: Diffusion Introduction: The human body undergoes a variety of processes throughout each and every day in order to sustain life. Tasks such as walking, breathing, and digesting what has been eaten are sometimes considered mundane, even taken for granted. One such process that is necessary to maintain life is diffusion. Diffusion is a key factor in moving ions, fuels, and other molecules into and out of the blood. It is one of the most important components in supplying oxygen to the alveoli and removing carbon dioxide.... [tags: essays research papers]
