HIV/AIDS: A Global Epidemic

Human Immunodeficiency Virus also known as HIV is the virus that causes AIDS. HIV is a disease that attacks the immune system specifically targeting CD4 cells or T cells. HIV makes you more susceptible to certain types of cancers and infections that our bodies would normally resist such as pneumonia and meningitis (The Mayo Clinic, 2010). Acquired Immunodeficiency Syndrome is a global epidemic. There is an estimated 39.5 million people living with the virus today (The Mayo Clinic, 2010). Approximately 2.0 million people died from aid in 2008 (WHO, 2010). AIDS is developed in the final stage of the HIV infection.

A person can live symptom free with the HIV infection for an extended period of time. Years may go by before the virus is even detected. To move from an HIV-positive diagnosis to an AIDS diagnosis, one must have one of 23 indicator diseases and have a T4 (or CD4) cell count of less than 200 (Mulvihill, Zelman, Holdaway, Tompary, Raymond, 2006). A normal count ranges from 800 to 1,200 (The Mayo Clinic, 2008)

HIV is a very delicate virus. This virus will not last long outside the body. Because of this fact, the HIV infection cannot be transmitted through daily activities like greeting by shaking hands, hugging an infected person, or even through kissing. This disease is transmitted via contaminated body fluids including blood, semen, and vaginal secretions (Mulvihill, Zelman, Holdaway, Tompary, Raymond, 2006). HIV is also transmitted through sexual intercourse (anal, vaginal, or oral) or by the use of intravenous drugs. Babies exposed to the virus during birth or through breast milk are also at risk. The symptoms of HIV and AIDS are similar but do vary depending on the stage of the disease. Symptoms at

...Ethics: HIV/AIDS Name Institutional Affiliation Date HIV/AIDS for over three decades has been a global epidemic affecting all races, genders and ages. The prevalence of the calamity has not been limited by any borders as it has traversed the entire world to emerge as a global threat. Despite the emergence of other health epidemics such as Ebola and lately the Zika virus, HIV has remained not only as a giant slayer but also as a multitude slayer killing millions of victims since its inception into the earth’s surface. HIV is categorised as a virus, and it attacks the human immune system thus decreasing the ability of the human body to fight diseases while suppressing the multiplication of unwanted or dangerous cells such as cancer cells (Stolley & Glass, 2009). The origin of HIV/AIDS nonetheless is not without controversies with various theories as to how the condition emerged in existence. Despite the existence of the many controversies, there is the wider belief that HIV has its origins in the nation of the Democratic Republic of Congo specifically in Kinshasa around the 1920s. The most common answer to the origin of HIV/AIDS by scientists is that it originated from primates of a non-human kind in the form of human immunodeficiency virus (HIV) in Africa (Crawford, 2013). While it is believed that the virus had other sub-groups that equally gained human infectivity, the prevalent global catastrophe is associated a particular strain which is the HIV-1 that emerged in...

Hippa Laws for Hiv and Aids

...What is HIPAA's confidentiality laws for HIV and AIDS Melinda Royalty HCR220 Ashley Spencer January 18, 2015 What is HIPAA's confidentiality laws for a patient with HIV or AIDS? Are the regulations and laws different for these patients? These are important questions for the patients that are screened and have come back with a positive diagnosis. It is always important to know what your rights as a patient are. Many people don't know that the regulations and laws are no different for a patient with HIV or AIDS, but for patients with these two conditions their treatment is more complex and is handled differently than most other cases. They have a higher confidentiality rate than say somebody with cancer because of the discrimination that the patient could face if their diagnosis was known by the public. Why do HIV and AIDS patients have a higher confidentiality rate, because these patients are at a higher risk of being discriminated against than most other patients. (HRSA, N/A) For these patients their day to day lives can be turned upside down if their diagnosis is publicly know. Patients with HIV or AIDS can face discrimination against them by the health care field, some housing authorities, and within their place of employment. (HRSA, N/A) When HIV was first discovered there was such a widespread fear of it because nobody knew how it was spread. This lead to many people with this condition to be fired from their place of employment...

Olujide Adekeye, Augustine Ebiai and Sussan Olufunmilola Adeusi Department of Psychology, Covenant University, Ota, Nigeria E-mail: oadekeye@covenantuniversity.com, aebiai@yahoo.com, funmiswayas@yahoo.com Abstract The aim of the present study was to assess attitude of young people (n=287, mean=20.5 years) towards testing for HIV/AIDS. The participants completed a standard socio-demographic questionnaire, indicating sexual behaviour, cultural beliefs and practices, attitude to HCT, and knowledge of HIV/AIDS. Descriptive and inferential statistics at 0.05 alpha level were used to analyze the data. The study indicates that most participants have poor knowledge of HCT centres in their communities, but had a fairly high knowledge level of HIV. The findings of this study include that there is a significant difference in the disposition to HCT between respondents who have experienced sexual intercourse and those who have not (t = 3.866, df = 285: p<0.05) and between male and female respondents (t = 4.775, df = 285; p< 0.05). The study also shows that knowledge of HIV/AIDS was the strongest predictor of attitude of young people towards HCT ( = 0.547; t = 3.458 p<0.05), closely followed by cultural practices ( = 0.324; t = 2.740 p<0.05)...
