Hiv And The Human Immunodeficiency Virus

HIV or the Human Deficiency virus is like other viruses including the flu, but the one thing that makes this virus so different than any other is that the body is unable to clear this one out completely. Once someone is infected, there is no cure. Over time, HIV can also hide or mask itself in the body's cells. The cells within a person's body that fight off infection are called CD4 cells or T cells. HIV attacks these cells and copies or replicates itself inside these cells, then destroys them. HIV over time will destroy so many of these cells that the body is unable to fight off infection anymore. When this starts happening, AIDS or Acquired Immunodeficiency Syndrome happens which is the final stage

Human Immunodeficiency Virus is HIV that develops into AIDS, which is Acquired immunodeficiency syndrome. This virus starts to break down white blood cells, as a result the immune system starts to deteriorate and our greatest shield cannot fight any longer (Mayo Clinic, 2016). The CDC (2015) states, that over 1.2 million people live with HIV in the United States and most who are infected are oblivious of their disease. Healthy people 2020 has declared HIV a public health crisis in the United States, and continues to sweep the nation with more than 500,000 new cases each year (HealthyPeople2020,2016).

HIV stands for human immunodeficiency virus and can lead to acquired immunodeficiency syndrome (AIDS) if not treated (About HIV/AIDS, n.d). Unlike some other viruses, the human body cannot fully rid itself of HIV completely, even with treatment. Simply put, once you contract HIV, you have it for life. This disease attacks the body’s immune system, specifically the CD4 cells (T cells), which help the immune system stave off infections. When left to its own devices, HIV reduces the number of CD4 cells (T cells) in the body, making the person more likely to

HIV and AIDS have affected millions of people throughout the world. Since 1981, there have been 25 million deaths due to AIDS involving men, women, and children. Presently there are 40 million people living with HIV and AIDS around the world and two million die each year from AIDS related illnesses. The Center for Disease Control estimates that one-third of the one million Americans living with HIV are not aware that they have it. The earliest known case of HIV was in 1959. It was discovered in a blood sample from a man in Kinshasa, Democratic Republic of the Congo. Looking further into the genetics of this blood sample researchers suggested that it had originated from a virus going back to the late 1940’s or early 1950’s. In 1999,

Human immunodeficiency virus, also referred to as HIV, came to the forefront of disease research in the 1980s as the disease began to spread throughout the world, eventually reaching pandemic status. HIV is a viral disease that targets the body’s immune system, and can potentially lead to acquired immunodeficiency syndrome, AIDS. Currently there is no cure for HIV; however, there are treatments available that prolong the lives of the infected individuals and are successful in controlling the disease. Research for HIV is ongoing, and discoveries are still being made about how the disease works and functions once inside the body. In addition to research, advancements in treatment have been made, setting a precedent for more effective

Human Immunodeficiency Virus (HIV) is a fairly common diagnosis with an estimated 1.1 million people in the United stated who carry the infection and is predominantly seen in homosexual Caucasian and black males.1 Prognosis for individuals with HIV is vastly different and is dependent on many different variables. The Center for Disease and Control (CDC) has classified the HIV virus into 3 stages based on the symptoms and the pathological progression of the virus. The first stage of the virus lasts usually one to four weeks, which presents with similar symptoms of mononucleosis (2 p 367). Stage two of the virus roughly lasts about ten years, at which point the CD4+ t cell levels drop to around 1000 cells/microliter (2 p367). During the final stage, stage 3 occurs when the CD4+ T cells levels drop to 200 cells/microliter, and the person is now infected with AIDS and the progression of the infection may be very rapid (2 p367). Ultimately, the human immunodeficiency virus or HIV is a complex immune virus that is capable of destroying ones immune system, leaving their body defenseless.

Aids stands for an acquired immune deficiency syndrome and is caused by a virus called HIV or Human Immunodeficiency Virus. The immune deficiency was discovered and informed in the early 1980’s. This deficiency takes over the body, making humans much weaker and susceptible to catching diseases and infections. As HIV grows, it gets stronger and the syndrome progresses. Doctors are

HIV is a disease which eventually kills ones immune system, and as time progresses it leads to AIDS. When the HIV enters a human, it attaches itself to a CD4 receptor and continues to enter the T-Cell. It then reprograms the cell to produce more HIV using the enzyme, reverse transcriptase. The HIV then leaves the host cell, but kills it before it leaves. Then, the HIV cells attach their selves to new T cells, and infect those as well. After about 12 weeks, the HIV antibodies appear in the humans blood stream. The disease starts off with a fever, sweats, headache, sore throats and enlarged lymph nodes. Once the CD4 cell count decreases to 200 um, AIDS gets developed and the low T count cell lowers ones immune system. Then, the

HIV is an epidemic throughout all corners of the Earth, an estimated 35 million people were living with HIV globally at the end of 2013 according UNAIDS, and approximately 1.7 million People die of AIDS annually. There are so many reported cases of HIV/AIDS around the world, because it is so easily transmitted between individuals; HIV is transmitted through the mixing of body fluids via sexual intercourse, use of un sanitized medical equipment, during birth and while breast feeding. HIV attacks the immune system by destroying CD4 cells, which is a specific type of white blood cell that plays a major role in helping your body fight disease. Your immune system weakens as more CD4 cells are killed. You can have an HIV infection for years before it progresses to AIDS (4). HIV also uses the CD4 cell to multiply, as shown on figure

On September 24, 1982 the U.S. Centers for Disease Control and Prevention used the term AIDS (Acquired Immune Deficiency Syndrome) for the first time and the released the definition “a disease at least moderately predictive of a defect in cell-mediated

The human immunodeficiency virus develops in stages; there are three established stages in total of the virus. The stages of HIV infections include the Acute HIV infection, followed by the Clinical Latency phase, and eventually reaching the last stage, Acquired Immunodeficiency Syndrome (AIDS). The Acute stage exists between 2-4 weeks after HIV infection when trivial infection symptoms like fever, are symptomatic in some patients. After the Acute

By the end of 1981, there were about 270 reported cases of AIDS among homosexual men and around 45 percent of the them died. This created a theory among people that only homosexuals could contract these illnesses and in 1982, it was initially called gay-related immune deficiency (GRID) but later renamed to what we know now as Acquired immune deficiency

Most of them do not know they carry HIV and may be spreading the virus to others. Here in the U.S., nearly one million people have HIV infection or AIDS, or roughly one out of every 250 people. At least 40,000 Americans become newly infected with HIV each year, and it is estimated that half of all people with HIV in the U.S. have not been tested and do not know they are carrying the virus.

HIV is a virus that is spread almost all over the world. Although in some places health care isn’t as developed and therefore it spreads more in those regions. Sub-Saharan Africa holds more than 70%, 25 million, of all HIV positive people in the world. Second highest is Eastern Europe together with Central Asia with 1.3 million. It is spread over most of the world, including Asia and the Pacific, the Caribbean, Central and South America, North Africa and the Middle East and Western and Central Europe (“The Regional Picture”).

The human immunodeficiency virus (HIV) epidemic has spread to every country in the world and has infected 59 million persons worldwide, including 20 million who have already died. CDC estimates that about 56,000 people in the United States contracted HIV in 2006 (1). HIV is the virus that leads to acquired immune deficiency syndrome, or AIDS. In terms of fatalities, with more than 35 million deaths, the AIDS epidemic now ranks alongside the influenza pandemic of the early 1900s and the Bubonic plague of the fourteenth century(4).
