INTRODUCTION
HIV/AIDS
The Acquired immune deficiency syndrome (AIDS) was first identified as a distinct new disease in 1981. In 1983 HIV was identified at the causative agent for AIDS. The mean time from HIV infection to AIDS is approximately 10 years. There is no effective medicine to cure it and the infected individuals do not recover: that is, they continue to be infectious throughout their lives. HIV infection is a complex mix of diverse epidemics within and between countries and regions of the world, and is undoubtedly the defining public health crisis of our time. The AIDS is a disease of the human immune system caused by the human immunodeficiency virus (HIV). It becomes an important infectiousdisease in both the developed and developing countries. AIDS is a fatal disease which destroys the human’s immune system, leaving the victim vulnerable to a host of life threatening infectious, neurological disorders and unusual malignancies. The AIDS epidemic is one of the most destructive health crises of modern times, ravaging families and communities throughout the world. By 2012, more than 36 million people had died, an estimated 75 million were living with HIV. The most common ways in which HIV is spreading throughout the world include (i) sexual intercourse, (ii) sharing contaminated blood products or needles and (iii) by vertical transmission from infected mothers to their new born during pregnancy, labor (the delivery process) or breastfeeding. HIV infection is generally a slow progressive disease in which virus number in the body is a major indicator of the disease stages. In a normally healthy individual’s peripheral blood, the level of CD4+ T-cells is between 800 and 1,200/mm3 and once this number reaches 200 or below in...

...cused of being patient zero and the one who purposely and knowingly infected as many as 250 men a year on both sides of the Atlantic was nothing but one of the many wrong hypotheses made in this process of finding the origin of the HIV/AIDS virus. The fact that he had single handedly started the epidemic, today is largely discredited by most scientists. With time computer models estimated that the first human infection occurred around 1930, give or take 20 years. The earliest known infection of an identified human dates back to 1959 which was found in a plasma sample taken from an adult male living in the Belgian Congo. Many assumptions and hypotheses were made and a human eating a chimp seems to be the likeliest form the infection occurred.
This virus searches for a new vulnerable host in order to survive and carry the disease to the next victim. The critical aspect around the spread of a virus is how drastically the reproduction process occurs. Without being controlled, the contamination throughout any species causes the spread to take place in a toxic way, “On day one, there were two people. And then, four, and then, sixteen. In three months, it’s a billion.
Almost no one on Earth has any immunity at all to this virus, which makes ordinary vaccines useless against it. The sudden spread of the virus into Europe foreshadows an epidemic development that could be worldwide. Ultimately, there is no way to protect ourselves against epidemics. They will keep disappearing and coming back in new forms.
Different people define success in many different ways. What is considered success by one person may be viewed as failure by another person. Randy Shilts, a homosexual newspaper reporter / author, attempts to make fundamental changes in America’s opinion on AIDS. In Randy Shilts’s essay, "Talking AIDS to Death," he speaks of his experiences as an "AIDS celebrity." At the core of Shilts’s essay is the statement, "Never before have I succeeded so well; never before have I failed so miserably"(221). Shilts can see his accomplishments from two points of view- as a success and as a failure. Despite instant fame, Shilts is not satisfied with the effects his writings has on the general public. Shilts’s "success" and reasons for failure can both be considered when one decides whether or not his efforts were performed in vain.

Acquired Immune Deficiency Syndrome (AIDS) was first recognized as a new disease in 1981 when increasing numbers of young homosexual men succumbed to unusual opportunistic infections and rare malignancies (Gallant49).During this time, many people were contacting this disease because it was not discovered yet and people did not have knowledge about it.Scientists believe HIV came from a particular kind of chimpanzee in Western Africa. Humans contracted this disease when they hunted and ate infected animals. A first clue came in 1986 when a morphologically similar but antigenically distinct virus was found to cause AIDS in patients in western Africa (Goosby24). During this time, scientists had more evidence to support their claim about this disease. Once discovered this disease was identified as a cause of what has since become one of the most devastating infectious diseases to have emerged in recent history (Goosby101). This disease was deadly because it was similar to the Black Death, it was killing majority of the population. Since its first identification almost three decades ago, the pandemic form of HIV-1 has infected at least 60 million people and caused more than 25 million deaths ...

The increase of population density over the past century due to an overall increase in population and the desire of many to live in major city centres. This population density has an adverse affect on the spread of infectious disease as the more people the larger amount of contact between individuals. Due to this increased contact it only takes one sick individual to spread a disease to potentially thousands through the transferal of microbes. A well known example that demonstrates just how quickly this can occur is the influenza virus. New strains of this virus are constantly emerging and the spread of these strains is aided by the close proximity of people living in cities. One of the latest flu strains to break out is the H7N9 a type of bird flu which broke out in china in the 2013 flu season. China has one of the highest population densities in the world and this is possibly the reason they see such a high rate of outbreaks. The H7N9 influenza strain infected 28 people and killed 8 in the first 9 days of the virus being recognized. Once the virus was tracked back to its source, a poultry market in shanghai, the outbreak was contained. The SIR model is used to track the spread of fl...
The Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome, commonly known as HIV/AIDS is a disease, with which the human immune system, unlike in other disease, cannot cope. AIDS, which is caused by the HIV virus, causes severe disorder of the immune system and slowly progresses through stages which disable the body’s capability to protect and instead makes it vulnerable for other infections. The first blood sample to contain HIV was drawn in 1959 in Zaire, Africa while molecular genetics have suggested that the epidemic first began in the 1930s (Smallman & Brown, 2011). Currently, according to the Joint UN Program on HIV/AIDS, 35.3 million people worldwide are living with HIV. In 2012, an estimated 2.3 million people became newly infected with the virus and 1.6 million people lost their lives to AIDS (Fact Sheet, UNAIDS). It is due to the globalized international society that a disease which existed in one part of the world has managed to infect so many around the world. Globalization is narrowly defined by Joseph Stiglitz as "the removal of barriers to free trade and the closer integration of national economies" (Stiglitz, 2003). Globalization has its effects in different aspects such as economy, politics, culture, across different parts of the world. Like other aspects, globalization affects the health sector as well. In a society, one finds different things that connect us globally. As Barnett and Whiteside point out (2000), “health and wellbeing are international concerns and global goods, and inherent in the epidemic are lessons to be learned regarding collective responsibility for universal human health” (Barnett & Whiteside, 2000). Therefore, through all these global connections in the international society, t...
The AIDS virus is the most common disease, and with no cure, an infected person will die. It is estimated that 90 to 95 percent of AIDS infections occur in developing countries where the world’s worst living conditions exist.
Acquired Immunodeficiency Syndrome (AIDS) first came to light in 1981. There has been a long and arduous global effort on the prevention of HIV/AIDS. HIV is a virus that is spread through body fluids that affect the specific T-cells of the immune system. Without treatment HIV infection leads to AIDS and there is no cure for AIDS. HIV infection can be controlled and the importance of primary pre...

The field of medicine is another high subscriber to this forecasting technique. Potential diagnoses are frequently made based on a patient’s history or that of his ancestors and the calculated likelihood of him/her acquiring certain conditions. Statistics and probability aid in the decision making process of which test may be required for a given symptom and how a possible outbreak may be detected and contained. Strategies for isolating and dealing with diseases are often made with the aid of statistics on the percentage of a population that may have been infected and the probability of its escalation.
...ile the pandemic will absolutely leverage the rate of financial development, structural alterations are furthermore expected to be one of the prime economic hallmarks of the AIDS pandemic (Arndt 427-449). The effect of the HIV/AIDS epidemic can be visualized by the overwhelming change in mortality rate of South Africans. The yearly number of mortalities from HIV increased distinctly between the years 1997, when about 316,559 people died, and 2006 when an estimated 607,184 people died ("HIV AIDS IN SOUTH AFRICA"). Those who are currently assuming the burden of the increase in mortality rate are adolescents and young adults. Virtually one-in-three females of ages 25-29, and over 25% of males aged 30-34, are currently living with HIV in South Africa (UNAIDS). The good news, thanks to better supply of ARV treatment, is that life-expectancy has risen vastly since 2005.
