Download file to see previous pages Public spending on AIDS had reached tens of billions of dollars by early 1990s, with these costs including medical care, research, education, and blood screening.
Now there had been approximately 150,000 reported cases of AIDS, and estimates of between 800,000 and 1.2 million individuals diagnosed with HIV. Spatial-analytic analyses of the diffusion and distribution of AIDS in the United States have indicated that AIDS during the early 1980s was concentrated in major metropolitan areas in California, New York/ New Jersey/ Connecticut/ Rhode Island, and Florida, and has since spread outward from these core areas. Large cities in the United States have become central in the developing characterization of AIDS. Reported AIDS cases in the metropolitan areas of New York City, Los Angeles, San Francisco, Miami, and Washington, DC, account for nearly one-third of all cases nationally (Appendix A).
From tracking and analyzing epidemiological information over time, researchers and policy-makers have concluded that AIDS can only be transmitted through sexual contact, exposure to infected blood or infected tissue such as through needle sharing, infected blood products, or transplantation, or parentally. Following these conclusions, policy-makers and service providers have attempted to dispel widely held myths concerning the potential for AIDS transmission via casual and non-sexual contact and insect bites. Epidemiological data have continued largely to characterize AIDS as critical for men who have sex with men and injecting drug users; over eight in ten of the cumulative reported AIDS cases nationwide have occurred between these two groups (Appendix A).
With the rise in the numbers of individuals diagnosed HIV positive or living with AIDS, the nation has also witnessed an increasing diversity in the epidemiology of AIDS. The Centers for Disease Control and Prevention's (CDC) tracking of reported AIDS cases has indicated that, while the epidemiology of AIDS remains largely defined through the two behavioral categories of male homosexual/bisexual contact and intravenous/injecting substance use, there has also been an increasing incidence of AIDS among newly emerging at risk groups, particularly women and individuals of color. For women, intravenous/injecting drug use and heterosexual transmission have constituted the primary modes of transmission, while children have contracted AIDS primarily through prenatal exposure. Studies of reported cases to the CDC have also indicated that African Americans and Hispanics are disproportionately at risk of contracting AIDS, considering their representation in the United States population and compared to the White non-Hispanic population.
Race in particular has become a potent factor in the contemporary and changing portrait of AIDS. The emphasis on race as a significant indicator of AIDS transmission and as a descriptor of AIDS epidemiology reflects the ongoing radicalization of the condition. But while there has been a growing emphasis on the connections between race and AIDS incidence, the risk of AIDS has not remained confined to any particular group. Populations, for example, once thought to be at little risk of contracti ...Download file to see next pagesRead More

AIDS in the United States

20 percent of adults have AIDS in seven countries of this area of Africa. The initial slow reaction and lack of concern during the early 1980’s and beyond by the U.S. is clear today. Forty thousand new instances of the disease is reported each year but exactly how many persons are infected is not known because the method intended used to track AIDS is flawed and not likely to be fixed anytime soon. However, the social effect of AIDS has been widely acknowledged. This has served to inform the public and slow the progression of the epidemic but not in the African American community. The continuing proliferation of AIDS is allowed by the lack of appropriate vaccines and the virus’ ability to evolve as it invades, weakens and finally...

... and needle sharing among injectable drug users. There is no cure for AIDS, even while a number of drugs have been developed thazt enable the disease to be managed for at least a few years. Presently “80-90% of patients with AIDS have died within 3-5 years after diagnosis with AIDS” (State, 2007). One of the major problems with AIDS is that a person may become HIV positive but remain symptom-free for years. But they are capable of transmitting HIV within days of becoming infected. The lag time between becoming infected and the onset of full-blown AIDS has been one of the most difficult epidemiological factors to overcome (Fan, 2004). The World Health Organization estimates that there are at least 30 million cases of AIDS currently...

... Your Section December 3, Your email Address Living with a disease like HIV/AIDS is not easy. Not only can HIV/AIDS create psychological illnesses in others, but also, often people diagnosed with HIV/AIDS have co-morbid psychiatric conditions along with substance abuse disorder. There is not enough data present about the health services used by HIV/AIDS patients with mental illnesses and/or substance abuse disorder. The advances in medicine in the 90s, and the anti-HIV combination therapies made it possible for people with HIV/AIDS to live longer, thereby making chronic condition care a burdensome issue not only for the patient but for the service providers. This not only includes economic factors, but also the fact that effective...

HIV/AIDS is a major pandemic that continue to frustrate the efforts by African countries in their quest to attain the MDG 6 goals. HIV/AIDS continue to rage in Africa often sustained by poor cultures and extreme poverty. In the first article HIV/AIDS Epidemic Still Ravaging African Countries by VOA’s Kim Lewis, the author dispels the notion that some of the African countries are winning the war against HIV/AIDS. The article asserts that the pandemic continue to kill millions of Africans on a daily basis. The condition is worse since most victims of the disease use the antiretroviral drug thus sustaining the spread of the disease...

HIV/AIDS with Particular Emphasis on Poverty

“Several years of experience in addressing the HIV/AIDS epidemic have confirmed that the promotion and protection of human rights constitute an essential component in preventing transmission of HIV and reducing the impact of HIV/AIDS”3 “It is trite to say that law cannot be a panacea for all social ills… the use of criminal law will not be counter-productive, and it will not do more harm than good.4” Hence, special attention should be given to the principle of non-discrimination and equality, and the principle of due process, of international human rights norms, when crafting legislation or policy related to HIV/AIDS, in the light of past and ongoing discrimination and stigma against people living wi...

Liberalization of foreign investment and technology policy of the government is supportive of establishing industrial units in the country.

Analysis of OReilly v Mackman Case

Judicial review is a concept which is constitutionally undecided as it on one side, it shores up the rule of law, democracy, and pre-eminence of parliament by facilitating the courts to check the boundaries of government authority and on another side, the courts are open to the decision on the plants based on the fact of separation of authorities that are intimating with the verdicts of democratically elected institutions. Judicial review is not apprehended with the virtues of government assessment but deals with whether the deciding authority has remained within the legal boundaries and whether broad principles of rationality and fairness adhere. The constitutional basis of judicial review is debated as one view holds that it is...

Analysis of the Methods of 3 Research Papers about Child Abuse

Research ethics was maintained as the identity of the individuals participating was kept secret. As far as the validity of the study was concerned, the researchers attempted to use content validity in order to get an accurate response. The content validity focused on measuring off the ethnicities and gender percentages within the area and attempting to get a random sample of individuals via the phone. Their approach to random calling allowed for a significant random sample in the study. There were a few issues, however, with this type of approach. Those answering the phone sometimes were not always the desired individual, and not all of the desired people were surveyed. Different replacements did have to be used, and the attempt w...

Since the turn of the 20th century, Great Britain and Northern Ireland have experienced a great influx of foreigners migrating into the country due to pull or push factors.

It (Houghton, Jenkins and Ephirams, 1990) suggested that if humans reduce the green house gas emissions, climate change could be averted. Soon after this report came out, Dansgaard et al. (1993, 218) made another study, Evidence for general instability of past climate from a 250-KYR ice-core record. This research paper (Dansgaard et al., 1993, 218-220) approached the issue of climate change from a tangential angle and their conclusions indicate that global warming was not a human-made phenomenon. The authors (Dansgaard et al., 1993, 218-220) of this research study questioned the traditional geological notion of a stable Holocene and stated...
