As the world evolved health problems have evolved with it. One of the many health problems that medical professionals deal with today is HIV/AIDS. HIV is a virus spread through body fluids that affects specific cells of the immune system, called CD4 cells, or T cells. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. When this happens, HIV infection leads to AIDS (www.cdc.gov).
This is just one of the questions our group inquired about when we began our investigations into the latest of AIDS research. AIDS Acquired immune deficiency syndrome, AIDS, is a serious disease that becomes more and more common in our nation and around the world. AIDS is defined by certain criteria established by the U.S. Centers for Disease Control and Prevention based on lab evidence such as T4 cell count, the presence of certain diseases, and other conditions. WHAT CAUSES AIDS? This disease is caused by the virus known as Human Immunodeficiency Virus Type 1 (HIV-1) (Structure of HIV), which attacks cells in the immune system, leading to the system's inability to resist harmful organisms.
Human Immunodeficiency Virus is a dangerous, deadly disease among the human race. HIV is when the bacteria goes into the lymphocytes, and make the body believe the cell is a germ. Soon after, the immune system will begin to attack itself and will get weaker each time. HIV has infected thousands and thousands of people in the world, from Asia to Europe, to the United States. Millions are infected and this can last for a life time.
Introduction Even though there is a rapid advancement in medical inventions, still the human immunodeficiency virus (HIV) is the most challenging virus that will drag the human lives to the deadly disease acquired immunodeficiency syndrome (AIDS). It spreads its wings all over. HIV cannot be cured, but it can be prevented. It has become the greatest life threatening disease and affects unbelievably high percent of human beings. Nowadays, besides other deadly diseases, HIV/AIDS becomes more complex and crucial health issue that challenges several medical inventions.
These cells fight infections and various cancers. When HIV invades the body's CD4 T-cells, the damaged immune system loses its ability to defend against diseases caused by bacteria, viruses, and other organisms (Chipps 2). HIV progresses in stages based on the amount of virus in the blood. Stage one or the Initial Stage, is also called the Acute Retro viral Syndrome. During this stage fu like symptoms often appear within three to six weeks of exposure to the virus.
HIV is different, the human immune system can’t get rid of it and scientist are still trying to figure out why our immune system can’t clear it. HIV hides in your body for long periods and it attacks a key part of our immune system, your CD4 cells or T cells. CD4 cells are a type of white blood cell that circulate around our bodies, scanning for cellular abnormalities and infections (www.tcells.com). Which your body must have to fight the virus. AIDS stands for Acquired Immuno Deficiency Syndrome, which means that AIDS is the cause of a different virus, which is HIV.
"The 80s will go down as the decade that AIDS began. We want to know, - Why" (Bevan 27)? One of the reasons is the promiscuity of sexually active people during the 1980s and the sharing of intravenous hypodermic needles and syringes by drug users.Secondly, AIDS is caused by the human immunodeficiency virus, or HIV. This virus attacks the antibodies in a person’s immune system, thereby disabling that system. HIV works in an unusual way because it uses the immune system to its advantage.
Until recently it was believed that AIDS related deaths as a result of HIV infection were caused primarily by opportunistic infections, usually bacterial or fungal, gaining a foothold in an immuno-compromised individual. Many of these secondary infections are the result of T-cell mediated immunodeficiency induced by HIV. The sequels of HIV infection often leads to a neuropathological state as a result of unusual secondary infections such as Toxoplasmosis. Postmortem studies have demonstrated that in addition to secondary infection, neurological manifestations may be due to vascular events, tumors (CNS lymphoma) and direct HIV-1 infection. In humans, HIV is known to infect T-lymphocytes within the body binding to the CD-4 receptors present on the cell surface, but in the brain, recent studies have suggested that microglial cells and macrophages serve as the reservoirs of HIV.
Some might not know that AIDS is in fact the final stage of the HIV infection. HIV is the Human Immunodeficiency Virus that can only infect human beings. This is similar to many other viruses like the flu but there is one very important difference. Our bodies for some reason are not able to get rid of this horrible virus and scientist are still trying to figure out why this is ("What Is HIV/AIDS?," 2012). This virus weakens your immune system by destroying cells that are important to fighting disease and infection ("What Is HIV/AIDS?," 2012).
AIDS (Acquired immune deficiency syndrome or acquired immunodeficiency syndrome) is a disease progressive of HIV (Human Immunodeficiency Virus). AIDS and HIV are a very dangerous disease that ignore an individual’s race, gender, economic class or age group and can affect anyone at any time if they put themselves in a situation where they could be at risk. The virus compromises the body's immune system, causing it to break down and become less effective when combating illnesses and bacteria. Even a common cold could prove fatal to a person infected with AIDS or HIV. The disease alters the immune system, causing exposure to infections and illness far more dangerous for those positively infected.
