Infectious Disease
There is one sexually transmitted disease that everyone is afraid of and that is HIV or AIDS. It has been plaguing this country for years and other parts of the world for even longer. Scientist believes that the HIV virus came from a chimpanzee from Western Africa. They think the virus most likely jumped to humans when humans hunted these chimpanzees for meat and came into contacted with their infected blood (What is HIV / AIDS?, 2012) . After years the virus spread and infected multiple parts of African and then spread to other parts of the world.
HIV stands for Human Immunodeficiency Virus. This virus only affects human beings and what it does is weakens the immune system by destroying important cells. The cells it attacks are the T-cells or CD4 cells (What is HIV / AIDS?, 2012) . The human body has these cells to fight infections and disease. Therefore when it encounters the HIV virus the T-cells try to attack it but instead the HIV virus ends up invading those cells and uses them to make more copies of itself. Then when it is done it destroys them (What is HIV / AIDS?, 2012) . This process does not happen overnight. The HIV virus can lay dormant for a long period of time before an individual might know that they have contracted it.
Even when HIV is dormant it can still be spread to other human beings because HIV lives in semen, vaginal fluids, blood, and breast milk (Krantzler, PhD, MPH, 2007). There are specific ways one can contract the HIV virus. The most common way is by having vaginal, anal, or oral sex with someone who has HIV. Other ways one could contract the HIV virus are by sharing needles with infected people or being exposed to infected blood (Hiatt, Clark, & Nelson, 2010) . In addition if a mother has HIV and chooses to breast feed her child she can also expose her child to

...Infectious Disease HCA/240 March 4, 2012 Infectious Disease The purpose of this paper is to explain the inflammatory response to HIV and AIDS, describe the disease, how it is transmitted, and the environment factors that may make someone vulnerable to it. Additionally, this paper will identify standards and alternative treatments to HIV and AIDS, the methods used to control the spread of the disease and the consequences of not controlling it. Finally, this paper will include community health promotion and wellness strategies to help prevent the disease. AIDS was first noted in the early 1980s among men with multiple sexual contact with other men and drug users who shared hypodermic needles (Zelman, Raymond, Holdaway, & Mulvilhil. 2010). Since first note in the early 1980s HIV and AIDS have not been exclusive to men but have infected women as well. AIDS is now known as one of the top causes of death in women. HIV is the fourth leading cause of death among women today. HIV is growing among minorities and is the largest in African-American males, with a rate of 6% rate of an African-American male having the disease, and it is also higher with Hispanics more than Caucasians (Zelman, Raymond, Holdaway, & Mulvilhil. 2010). Subsequently, HIV and AIDS is not the same thing. According to the Center for Disease Control (CDC) AIDS is the full blown disease, while HIV is the virus that causes AIDS. First, Human immunodeficiency virus or HIV is the virus that...

...Infectious Disease HIV/AIDS Julie Maple HCA/240 October 7, 2012 Elizabeth Day Infectious Disease HIV/AIDS The Human Immunodeficiency Virus was discovered in 1985. HIV is a virus that is transmitted from one person to another by many different ways. For example, HIV can be transmitted by bodily fluids. It could be fluids like blood or semen that transmits the virus, because they came from the infected person into the other person. HIV/AIDS is commonly spread by sexual intercourse. I have also seen people get HIV/AIDS by sharing needles when using them for street drugs. HIV/AIDS reproduces, and as it reproduces, it tears down the body’s immune system, thus leaving the body susceptible to other illnesses and infections. The only environmental factors that could make a person vulnerable to HIV/AIDS would be the lack of recreational activities in the environment. There are also places in our neighborhoods that allow people to use drugs and engage in sexual activity. In my hometown there was this place at the community park called the rock. It was this huge rock that all the “cool” kids went to so they wouldn’t get caught doing their drugs or having sex. With HIV/AIDS there are two inflammatory responses. According to Brown (1995), “the production by B cells of antibodies which circulate all around the body in the bloodstream, and eventually bind to the agent. There are mechanics available which are very good at destroying anything which has antibody bound to...

...Infectious Disease Victoria Jay HCA/240 June 8, 2014 Natasha Brown Infectious Disease What is the inflammatory response? According to "Definition of Inflammatory Response" (1996-2014), it is “a fundamental type of response by the body to disease and injury, a response characterized by the classical signs of ‘dolor, calor, rubor, and tumor’ -- pain, heat (localized warmth), redness, and swelling.” A very important part of the body’s defense system is inflammation; this is when there is a crucial protective response by the body’s system of self-defense (Definition of Inflammatory Response, 1996-2014). Acute inflammation lasts only a few days, it is short-lived whereas chronic inflammation lasts longer; like weeks, months, and maybe even years. When the inflammatory process is involved in healing and repair it may cause tissue damage. Inflammation can play a role in many disorders; for example Alzheimer’s, asthma, diabetes, osteoporosis, and even HIV/AIDS. According to U.S. Department of Health & Human Services. (2012), “More than 1.1 million people living in the United States are infected with HIV and almost 1 in 6 are unaware of their infection.” Gay and bisexual men of all races are affected by HIV the most. Those are a couple of statistics to think about. HIV stand for human immunodeficiency virus. HIV hinders the body’s ability to fight the organisms that cause disease by harming the immune system. HIV is a sexually transmitted infection and it can also be spread...

...Infectious Disease (Shingles) Tomakio Robinson February 3, 2012 Jessica Grippo HCA/240 Shingles virus which the medical terms use is herpes zoster, which is accompanied by a local rash and pain. Shingles virus usually covers certain areas of the skin encompassing about one to three dermatomes. The dermatome area is supplied by just one single nerve root, shingles is known by blisters superimposed by an aggressive red inflamed base. Shingles virus only occurs on one side of the body, the pain of shingles is very severe and those who have experienced the shingles virus describe shingles as a burning sensation. The area of the body which is affected by shingles virus becomes very sensitive to the touch which is medically known as allodynia. When allodynia is present many people usually wear loose fitting clothing because shingles are very painful. Shingles is a reaction of varicella-zoster virus, which is a form of herpes that causes chickenpox. Once a person has had chickenpox, the virus from the chickenpox remains in the nerve roots and remain inactive until it begins to flare up again; but this time instead of chickenpox the individual will get shingles. If someone has ever had a mild case of chickenpox can catch shingles. Any individuals with a weak immune system are very vulnerable to activating the virus that forms shingles. There are many ways the immune system can become weak such as recent surgeries, medications, serious illness or disease and poor nutrition...

...Hepatitis Cancer Patient Information Glenda Aldape HCA/240 December 6, 2012 Pukar Ratti Hepatitis B is the most common liver infection in the world. Worldwide, about 350 million people are chronic carriers of HBV (Hepatitis B Virus), among these carriers, more than 620,000 die from liver-related diseases each year. In the United States, hepatitis B mainly affects adults aged between 20-50 years. About 800,000 to 1.4 million Americans are chronic hepatitis B virus carriers, and the disease causes about 3,000 deaths each year. The good news is that infection with HBV is usually preventable because there is an effective vaccine. Use of the vaccine has resulted in an 82% decrease in the number of new infections reported in the United States each year. (www.emedicinehealth.com/hepatitis/article_em.htm) Figure 1: Estimated and reported cases of hepatitis B in the United States. Rates have fallen significantly since 1991 when routine vaccination of children was started. (www.emedicinehealth.com/hepatitis/article_em.htm) Hepatitis B is an infectious hepatitis caused by the hepatitis B virus (HBV). This infection has two possible phases; 1) acute, 2) chronic. Acute hepatitis B refers to newly acquired infections. Affected individuals notice symptoms approximately 1 to 4 months after exposure to the virus. In most people with acute hepatitis, symptoms resolve over weeks to months and they are cured of the infection. However, a small number of people develop a very severe, life-threatening...

...ork2012 - 2013 Catalog A Message from the President “Sullivan University is truly a unique and student success focused institution.” I have shared that statement with numerous groups and it simply summarizes my basic philosophy of what Sullivan is all about. When I say that Sullivan is “student success focused,” I feel as President that I owe a definition of this statement to all who are considering Sullivan University. First, Sullivan is unique among institutions of higher education with its innovative, career-first curriculum. You can earn a career diploma or certificate in a year or less and then accept employment while still being able to complete your associate, bachelor’s, master’s or doctoral degree by attending during the day, evenings, weekends, or online. Business and industry do not expand or hire new employees only in May or June each year. Yet most institutions of higher education operate on a nine-month school year with almost everyone graduating in May. We remained focused on your success and education, and continue to offer our students the opportunity to begin classes or to graduate four times a year with our flexible, year-round full-time schedule of classes. If you really want to attend a school where your needs (your real needs) come first, consider Sullivan University. I believe we can help you exceed your expectations. Since words cannot fully describe the atmosphere at Sullivan University, please accept my personal invitation to visit and experience...
