Hiv Is An Organism Of Human Beings Better And Understand How The Organisms On Earth Fit Together

As a disease, HIV, or the Human Immunodeficiency Virus is a blood-borne virus that is transmitted from person to person via sexual intercourse, mother to child, or intravenous drug paraphernalia. The virus itself causes, usually over a period of time, Acquired Immunodeficiency Syndrome, or AIDS. AIDS actually targets the immune system and causes an immunosuppression which makes people who have the virus more susceptible to cancers and infections. This is the most unique feature of the HIV/AIDS virus and is the most deadly since its implications are destructive if not properly treated (Moore 51). The significance of this disease is one that began in the 1980’s and initially was thought to be a virus only found within homosexual communities and was even originally called Gay-Related Immunodeficiency Virus. However, in 1981, it was found that the virus was spreading beyond the gay community when Blacks accounted for 25% of the HIV/AIDs population and a trend began where Blacks continued to contract HIV significantly more than

HIV is a sexually transmitted disease that attacks the body’s immune system by diminishing CD4 cells that help prevent and fight illnesses. HIV is a virus, more specifically a retrovirus that transcribes its RNA into the host cell’s DNA, and is spread by a transfer in bodily fluids namely drug injection and condomless sex. As the disease progresses into acquired immune deficiency syndrome (AIDS), the virus continues eliminating CD4 cells until the immune system becomes virtually ineffective [5]. Scientists first identified HIV in 1985 in response to the AIDS crisis plaguing the United States [6]. With no cure yet available, those affected with HIV must rely on antiretroviral drug therapy to decrease their chances of developing AIDS [7].

What is HIV? It is a virus that attacks the body’s immune system that can lead to acquired immunodeficiency syndrome or AIDS if not treated. The Kaiser Family Foundation (2008), states that HIV attacks the body’s immune system, specifically the CD4 cells (T cells), which help the immune system fight off infections. If left untreated, it reduces the number of T-Cells in the body, making the person more likely to get other infections. Also noted is the fact that HIV destroys so many of these cells that it renders the body helpless in fighting off the infections, while it takes advantage of the weaker immune system. This occurrence is part of the

History: HIV was believed to have originated in the Congo, where it was transmitted when a human came in contact with a species of chimpanzee that had acquired the virus. From then on, the virus only continued to spread, where it could have been believed to infect anywhere from 100,000 to 300,000 people (“History of HIV and AIDS Overview”). The first forms of confirmed HIV discovered in the world took forms in two highly dangerous illnesses, Pneumocystis carinii pneumonia (PCP) and Kaposi’s Sarcoma. These rare diseases were first discovered and researched, although they didn’t know they were directly linked

HIV is a retrovirus that that contains RNA and is a member of the subfamily of viruses called lentivirus, in this group infection develops slowly. It

HIV-1, responsible for most of the disease today, was first discovered to have originated from Chimpanzees in 1999. HIV-2, the second type of the virus, was discovered to be transmitted through monkeys most likely through the consumption of their meat. There are two different types of the illness: HIV-1 and HIV-2. HIV, Human Immunodeficiency Virus, essentially breaks down the body’s CD4 cells which help to assist fighting off infections in your body. Overtime, this will hindrance your body’s ability to fight off diseases which can be potentially life threatening. The last stage of HIV is linked to AIDS, Acquired Immunodeficiency Syndrome. AIDS is a specific group of diseases/conditions that are indicative of severe immunosuppression related to infection with HIV. This makes people infected with the disease more vulnerable to opportunistic infections which their body will be unable to fight off towards the later stages of the disease. Most people diagnosed with AIDS have an estimated three years to live, but people that do not get diagnosed have an estimated one year to survive.

The Human Immunodeficiency Virus, also known as HIV, is a virus that attacks and destroys a person’s CD4 cells which are cells used to help fight

HIV is very popular in America HIV belongs to a group of retroviruses called lentiviruses. The genome of retroviruses is made of RNA. And every virus has two single chains of RNA, for replication, the virus needs a main cell, and the RNA must first be transcribed into DNA, which can be done with the enzyme reverse transcriptase. HIV infects mainly the CD4+ lymphocytes. It also to a lesser degree monocytes, macrophages, and dendritic cells. Once infected, the cell turns into an hiv-replicating cell and loses its function in the human immune system. HIV is a ball-shaped virus. It has two single strands of RNA for its genome. The RNA is made to carry the genetic information that passed on when new hiv particles are produced. This is different from a normal cell and it uses DNA to carry its genetic information.

HIV is a human immunodeficiency virus for which the virus is responsible for HIV infections. The virus attacks the immune system making it impossible for the immune system to fight off infections and diseases. HIV is a lentil retrovirus with a genetic complexity not seen previously among any kind of retrovirus. It operates in an inconspicuous nature comprising several parts: HIV destroys immunologically important white blood cells called T-helper cells (CD4+.) It goes inside a host cell DNA, where it can remain stays for extended periods and it inactively infects cells of monocyte lineage that can move throughout the body. It also has an affinity to nerve cells making it neurotropic and its antigenic biological properties are heterogeneous. However, HIV is distinct from acquired immune deficiency syndrome AIDS, which is the full syndrome that consequently damages the immune system. AIDS is a stage when an

The team was interested in tracing the evolution of hiv (human immunodeficiency virus) to investigate

HIV is a quite detrimental virus that has caused much disruption during the 1980’s when it came to life. HIV is “one of the fastest evolving of all organisms” (Rambaut A. ET. Al. 2004) HIV has found ways in which to resist drugs and shows evolutionary mechanisms. The HIV virus has also

To be a retrovirus is not the same as a virus. HIV is a retrovirus and it is classified as this because HIV’s genetic information is being enclosed by RNA instead of DNA. HIV targets a specific cell within the immune system and those are the T cells or also known as CD4+ cells. HIV causes immune dysfunction by destroying these cells. HIV contains a glycoprotein, called gp120 that is vital for the virus to enter the T cell. It attaches to the surface, called the CD4+. As it attaches, the retrovirus’ membrane fuses to the lymphocyte cell membrane, therefore gaining entry into the cell.

HIV is the human immunodeficiency virus that causes AIDS. A member of a group of viruses called retroviruses, HIV infects human cells and uses the energy and nutrients provided by those cells to grow and reproduce. AIDS (acquired immunodeficiency syndrome) is a disease in which the body's immune system breaks down and is unable to fight off certain infections, known as "opportunistic infections," and other illnesses that take advantage of a weakened immune system. When a person is infected with HIV, the virus enters the body and lives and multiplies primarily in the white blood cells. These are the immune cells that normally protect us from disease.

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 HIV belongs to the genus Lentivirus and the family Retroviridae. The members of the genus Lentivirus have different morphology and associate biological properties common for all. These viruses also infect and affect many species of the animal kingdom; the most affected being the human species. However, in the structures, the HIV has a relatively different structure from the other retroviruses. The HIV causing virus has a roughly spherical structure with a diameter of approximately 120 nm and around 60 times smaller than a red blood cell (Lowe 8). However, it is larger than the general structure of a virus. The
