HIV / AIDS
Autoimmune deficiency syndrome (AIDS) first came to the public's attention in the United States in the early 1980s. In Africa, the cities of Rwanda, Zaire, Zambia and Uganda were decimated, and cases began cropping up all over the world. In rare blood samples dating back to 1959, antibodies to HIV were detected (Crowley, 1993, p. 46), and yet the virus did not seem to become a problem until twenty years later.
It is not known how the virus carried by chimpanzees and harmless to them, was transmitted to the human population. According to Chang (2011), it is most likely that a hunter in West Africa killed a chimpanzee and was infected by the chimp's blood, probably through an open wound. The virus spread as colonial cities were established, but deaths were attributed to other causes. It is unknown exactly when this scenario occurred, but it is thought to have taken place between 1884 and 1924. Thus, AIDS is "an old virus that grew deadly" (Cowley, 1993) and has become epidemic in modern times.
Man has interacted with apes and monkeys for thousands of years. Scientists still do not understand why the human immunodeficiency virus (HIV), which causes AIDS, became deadly. A virus is a living organism; to survive, it must exploit its host and...
Nearly a century ago, the influenza virus mutated and spread rapidly, killing nearly twenty million people worldwide. Scientists have suggested that the spread of HIV has followed a similar course.
People afflicted with AIDS, because of their compromised immune systems, are vulnerable to infections and tumors that may not be fatal in people without the disease. Kaposi's sarcoma, for example, is ordinarily a slow-growing cancer but moves quickly in patients who are HIV positive (Medline Plus, 2011).
AIDS quickly got the reputation for being a "gay disease," since the first cases in the United States were seen in young homosexual men. Doctors from the Centers for Disease Control (CDC) reported on a rare parasitic lung infection that had shown up in Los Angeles; the "active homosexuals" tested positive for "an inexplicable depression of their immune function" (Begley, Check, Wingert, and Conway, 2001, p. 34). Movie fans were shocked to see photos of an emaciated Rock Hudson, who eventually died from AIDS. Hudson's death was shocking because of the dramatic change in his appearance as well as the realization that Hudson, handsome, masculine co-star of the film classic Giant, in addition to a string of romantic comedies with Doris Day, was a gay man. Reverend Jerry Falwell called AIDS "proof of society's moral decay," while conservative columnist Pat Buchanan deemed the…
In other words, people become so depressed and fall into such a state of despair upon hearing that they have HIV that their immune system is weakened, which is the real cause of developing AIDS. Null blames doctors for creating a self-fulfilling prophesy in the mindset of people diagnosed with the illness, even in the minds of children. He believes that children who do not understand what causes various types
Origin of HIV The mystery of HIV and its origins is one that cannot be easily solved. In the thirty-odd years which have passed since the official recognition of AIDS by the CDC and the subsequent search for its cause, various theories have been floated regarding its nature, its development, its ability to adapt, our ability to combat it, and -- most importantly for some -- its origin. How did the
Nephrotic Syndrome is not a disease. It is a condition that is characterized by damaged glomeruli in the kidney. This damage might be caused by one or more disease. These diseases can be related to the kidney as in Familial Focal Segmental Glomerulosclerosis, abbreviated FFGS or membranous nephropathy. Or it can present from relatively distantly related diseases such as heart diseases, hypertension, diabetes and lupus. The types of diseases that
Immune System and Stress How quickly a deceased human (or animal) body breaks down is testament to how well the immune system works. While a body is alive, the immune system protects the body at every living moment from bacteria and other foreign invaders. The immune system is a complex system of cells -- which have varying functions -- and generated at discreet regions of the body, a circulatory system --
The viruses that cause AIDS (HIV) and hepatitis can be carried in clotting factors however there have been no documented cases of such transmission in about ten years. Prevention of viruses can be prevented by: careful screening of donors; testing of donated blood products; treating donated blood products with a detergent and heat to destroy viruses (Hemophilia 2006). Both preventive and as-needed therapy can be administered at home, thus
Abstract This paper provides an extensive review of literature on deaf students and deafness. The purpose of the literature review is to obtain an understanding of what deafness is, what causes deafness, how it occurs, and what deaf culture is like for deaf people. The review identifies schools and programs that are used to help the deaf community and it also examines the outcomes of deaf students in general education. It
