...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 Diseases Sharelle Taylor HCA 240 Inflammation occurs when there is sickness or some type of injury to the body. Injured cells release a certain chemical that lets the immune system know that there is something wrong. They attract healing cells which are sent out to work on damaged tissue. HIV/AIDS is transmitted through many bodily fluids. These fluids are Blood, Semen, Pre-seminal fluid, Breast milk, vaginal fluids, Rectal mucous. Other body fluids and waste products...

...virus but HIV invades them and destroys your immune system. After HIV has destroyed your CD4 cells your body cant fight them any longer and then HIV turns into AIDS. AIDS is Acquired Immune Deficiency Syndrome, which is the final stage of HIV infection and when you reach this stage your immune system is shot which puts them at risk for opportunistic infections. People believe that HIV came from a chimpanzee in Western Africa. Humans came in contact with HIV when they hunted the affected animals. It could have gone as far back as the late 1800’s. HIV has not infected and has spread to every country in the world. Statistics show that 40 million people are currently living with HIV infection, and an estimated 25 million has died from the disease. 85% of HIV transmission is through heterosexual intercourse, and in the United States approximately one third of new diagnoses appear to be heterosexual transmission. Male to male contact still accounts for more than HALF of the new diagnoses in the U.S. and drug use contributes to that as well. The diagnosis may...

...Infectious Disease What is the stake of the American People and the Government by International Agencies to control Infectious Disease in Developing Countries? More people are at risk of infectious diseases than at any other time on history. Infectious diseases are worldwide problem requiring worldwide attention. Infectious diseases can weaken the strength of a nation's resources. In developing nations this poses even a greater threat. Diseases are threatening the economic stability of many developing nations. 50,000 people die everyday from infectious disease. Rift Valley Fever infects both livestock and humans. Rift Valley Fever is most commonly found in regions of eastern and southern Africa. It also exists in Madagascar and sub-Saharan Africa. The Bunyaviridae family includes the Rift Valley Fever disease. It is primarily spread from infected mosquitoes, who then infect animals. Generally they infect domestic animals, such as buffalo, cattle, sheep, camels and goats. Once the livestock are infected, other mosquitoes can spread the disease. It is also possible that the infection can be spread from other biting insects. The Rift Valley Fever outberak of 1997-1998 in eastern Africa killed both humans and livestock. It economically hurt trase in animals and the dairy indusrty.. the economy was crushed by trade imbargoes. Humans can get Rift Valley Fever in numerous ways. Humans can be infected from the mosquitoes or the bodily fluids of the infected animal...

...Chronic and Infectious Diseases Chronic and infectious diseases are diseases life threatening. A chronic diseases are non-communicable illnesses prolonged in duration, do not resolve spontaneously, and are rarely cured completely such as heart disease, cancer, stroke, diabetes, and arthritis (Centers for Disease Control and Prevention, 2009). However, an infectious disease or communicable disease is contagious and caused by a biological agent, such as a virus, bacterium, or parasite also known as pathogens (The Metro Health System, 2002-2012). There are some diseases, such as hepatitis B, hepatitis C, human immunodeficiency virus (HIV), and acquired immune deficiency syndrome (AIDS). Characteristics of a chronic disease, examining the relationship between a healthy nutritional diet, and cardiovascular disease, the effects of chronic, and infectious diseases, how exercise affects the immune system, and consumer awareness are the focus of this paper. Characteristics of a Chronic Disease Chronic diseases are often hard to detect because the disease spread slowly. According to UCLA Center for Neurovisceral Sciences and Women's Health (n.d.), “chronic illnesses also have multiple causes varying over time, including heredity, lifestyle factors, exposure to environmental factors and physiological factors” (Chronic Illness). Individuals who smoke cigarettes put him or her at risk of several types of chronic illnesses. “Cigarette smoking is an independent risk factor for lower extremity...

...Emerging and Remerging Infectious Disease: A Global Challenge Liberty University Emerging and Remerging Infectious Disease: A Global Challenge Emerging and re-emerging infectious diseases is a danger to the stability of nations and the world. Governments, international organizations and individual health professions have renewed their focus on current health care policies in an effort to reduce the threat of emerging infectious diseases (Simmerman, 2012). The basic definition of an emerging or re-emerging infectious disease is a disease whose incidence has increased in a defined time period and location. If the disease was unknown in the location before, the disease is considered to be emerging. However, if the disease had been present at the location in the past and was considered eradicated or controlled, the disease is considered to be re-emerging ("Emerging and Re-emerging Infectious Diseases," n.d.). Some of the diseases identified as emerging and re-emerging are the Avian influenza (H5N1), West Nile virus, Monkey pox, and severe acute respiratory syndrome (SARS), which an increase in outbreaks was noted in early 2003 (Simmerman, 2012). Emerging infections are caused by pathogens that are present in the environment and when these opportunistic pathogens are given the right conditions, they are able infect new host populations. Another major factor is infections that are antimicrobial drug resistant. In order to meet the challenge of these infections healthcare providers...

...Taurean Bullard March 4, 2012 What is the infections agent (pathogen) that causes this infectious disease, the name of the bacteria, virus, or parasite? Staphylococcus Aureus is the infectious pathogen that can cause a variety of illnesses from minor skin infections like boils, carbunkles, cellulitis, impetigo, abcesses and of course staph infection. This pathogen can also lead to life-threatening diseases such as pnuemonia, menengitis, toxic shock syndrome, bacteremia, and sepsis. How is this infectious agent transmitted through food or water? This infectious agent can be transmitted by skin, soft tissue, respiratory, bone, joint, endovascular to wound infections. It is also carried in the respiratory tract, nasal passages. It can also be transferred onto clothes, bedding and on the skin of carriers. If someone that is a carrier doesn't wash their hands properly then the staph can easily get into any food or drinks they handle and thus be transferred to someone else. Infections may spread through contact with pus from an infected wound, skin-to-skin contact with an infected person by producing hyaluronidase that destroys tissues, and contact with objects such as towels, sheets, clothing, or athletic equipment used by an infected person. What is an example of a real life outbreak of this foodborne illness in the United States? There was an outbreak of Staphylococcus Aureus at the World's Fair Park event site July 30, 2005. This event took place in Knoxville...

...Step 1 Why do poor countries have a predominance of infectious diseases as opposed to the lifestyle-related diseases of wealthy countries? What is your response to the global health inequalities that exist? Step 2 Willi’s social imagination template has been a helpful tool for this topic. It helped me to understand how four factors can affect the way people live. The template consist of four different factors; historical, structural, cultural and critical. This has helped me understand how one factor links to the other that has resulted in different health issues around the world. In order to understand each factors, (Germov,2009) explains that history refers to how the past influences the present. Culture refers to how culture impacts on our lives. Structural factors refers to how particular forms of social organisations such as media, politics, technology, etc affect our lives while critical factors refers to how we can improve our actual environment. Based on my readings about Thailand as well as Australia, I found that there are extreme differences between the two. Even though Thailand is still developing while Australia has already developed, in Thailand there is a high risk of developing numerous infectious diseases due to malnutrition, poverty, hunger, agriculture, pollution, poor sanitation, HIV/AIDS and other diseases, no electricity supply, social and cultural exclusion, war, poor water quality, and inadequate health care food (Nikhil Ghimire, 2014). While people...

...Title: Infectious Disease paper on HIV/AIDS By: Susan Rhine Date: June 17, 2012 Class: Health and Diseases Teacher: Alexis Deavenport Infectious diseases are rampant throughout the world and only seem to be getting worse. Some of these diseases are treatable, but some are still untreatable even with many years of research. Some of these diseases include: Tuberculosis, HIV/AIDS, Influenza, Chickenpox, Methicillin-resistant Staphylococcus Aureus(MRSA), Clostridium difficle, Hepatitis B, and Rotavirus. Any of these diseases if contracted, can cause death. The one disease that I would like to discuss today is HIV/AIDS. This is one of the most deadly diseases in the world today. If a person has HIV does not necessarily mean that the person will also have the AIDS virus; it just means that they have the virus that causes AIDS. However; if a person has AIDS, then they will also have HIV because it is the virus that causes AIDS to be brought on. Unfortunately, the spread of AIDS has been great since the year 1981, with over 980,000 cases reported in the United States alone. It is important to know that HIV and AIDS are not the same disease. HIV stands for Human Immunodeficiency Virus and is a virus that can be caught on contact. HIV can eventually turn into the AIDS virus even though it takes time varying in length from a couple months to years. AIDS stands for Acquired Immune Deficiency Syndrome. When the HIV virus ends up attacking a person’s immune system...

...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...

...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 diseases are now the world's biggest killer of children and young adults. They account for more than 13 million deaths a year - one in two deaths in developing countries. Over the next hour alone, 1 500 people will die from an infectious disease - over half of them children under five (WHO, 1999). The main causes of these deaths from infectious diseases occur in developing countries - the countries with the least money to spend on health care. Instead of this, in wealthy countries people are suffering from non-communicable diseases, just because of their illness related behaviour.Non communicable diseases are the top cause of death worldwide, killing more than 36 million people in 2008. Cardiovascular diseases were responsible for 48% of these deaths, cancers 21%, chronic respiratory diseases 12%, and diabetes 3% (WHO, 2011). This health inequality effects not just how people live, but often dictates how and at what age they die. In this essay I would like to reflect upon the main causes, preventions about all diseases whether it is infectious or lifestyle related diseases, and my response to the global health inequalities that is existing. According to Willi (2004) the sociological imagination consist of four interrelated parts:1) Historical factors, 2) Cultural factors, 3) Structural factors, and 4) Critical factors. I would like to explain historical factors in relation of my topic. I am born and grew up in Asian region, there People are likely to try native...

... | |Infectious Diseases | | | | | African trypanosomiasis or sleeping sickness as many call it is a parasitic disease that can be contracted by either human or animals. The disease is transmitted by the tsetse fly which can be found all over Africa but the ones contaminated with the disease are found in region of sub-Saharan Africa. The disease has been said to have been in Africa since way back in the 14th century and one of the first epidemics that was recorded happened in 1901 in which a "devastating epidemic had erupted in Uganda, killing more than 250,000 people, about two-thirds of the population in the affected lake-shore areas" (CDC). According to the World Health Organization the disease covers 36 countries and 60 million people. The majority of the affected population live in remote areas of sub-Saharan Africa with little access to health care clinics which is why in these rural area the disease often goes untreated and misdiagnosed. The distribution of African trypanosomiasis...
