Human Immuno Deficiency Virus ( Hiv )

The disease AIDS is an acronym for acquired immunodeficiency syndrome. The first known case of the AIDS virus was found in 1970’s. The AIDS disease was made aware in hospitals among male patients who had same-sex relationships. The two main areas of this disease at that time was in New York and Los Angeles. “In 1982 the AIDS disease was enhancing Kaposi 's sarcoma and Pneumocystis jirovecii pneumonia” (Scavnicky, 2011). In order for a person to be diagnosed with AIDS is due to having the HIV virus. The first HIV virus was detected around 1950. It was considered to have originated from monkey’s or chimps. It later had been spread to humans. The AIDS name had surfaced after the latter stages of HIV have

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,

In the past four decades, human immunodeficiency virus (HIV) has been discovered, developed into an international epidemic, and

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.

HIV is mainly spread by sexual behaviors and needle or syringe use. Human fluids such as: Blood, Semen, Pre-seminal fluid, Rectal fluids, Vaginal fluids, Breast milk can transmit HIV to other people. HIV cannot be spread by air, water, dry body contact, and drinking fountains.There were some stories from people who received HIV by holding hands and hugging with a person with HIV. Another myth was that it was a homosexual disease. Lastly some people said that they have HIV thanks to breathing the same air as people affected with the virus. Anyone that has unprotected sex or shared body fluids have a

AIDS (Acquired immunodeficiency syndrome) is disease caused HIV (human immunodeficiency viruses). This research paper describes the evolution and origination of HIV and AIDS. There are two types of HIVs. These are called HIV-1 and HIV-2. HIVs result multiple cross species transmission from SIV (simian immunodeficiency viruses) that is viruses that infects primates. HIV-1 comes from SIV from chimpanzees whereas HIV-2 comes from sooty mangabeys. HIV-1 has four sub groups these includes M, N, O, and P. Each of groups has resulted from independent cross-species transmission event. Group M is the most virulent, and it is the first to be discovered. HIV-2 has groups that ranges from A to H. SIV are infecting West Africa primates. This fact is based on the first pandemic HIV-1 has emerged in colonial West African, and most researchers have sampled primates from this region only. Newly emerged SIVs are resulted from multiple cross species transmission and recombination. The cross species transmission occurs from non-humans to humans through eating bushmeat. The cross transmission influenced by host restriction factors, but HIVs were able to pass this barriers. Most SIV are non-pathogenic to the host; however, there is some evidence that some are pathogenic to their host. The age of the virus determined by using molecular clock method. Other studies have estimated the evolutionary timescale with same age as

Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS) are lentiviruses (a subgroup of retroviruses) that infect CD4 cells (commonly known as T-cells), macrophages and dendritic cells. The Virus can be transmitted through the rectum, the vagina, the mouth, and the opening of the penis. Only certain fluids contain the virus. They are blood, semen, pre-seminal fluids, rectal fluids, vaginal fluids and breast milk. The HIV virus infects a T-cell, multiplies and eventually the cell explodes. When that happens on a massive scale, your immunity is compromised. That makes it possible for infections, such as the common cold and pneumonia, to thrive. That is usually in the end stages of the disease.

It has been over 30 years since the first known cases of HIV (human immunodeficiency virus) which is the virus that causes AIDS (acquired immune deficiency syndrome) was reported. HIV attacks and disables the body 's immune system. The virus attacks, the T lymphocyte (T cell), a type of white blood cell. Formed in the bone marrow the T cell helps the body fight off germs and diseases. Once HIV enters the body, it attacks this cell, copies itself and destroys the cell. Being HIV-positive indicates that a person has been infected with the human immunodeficiency virus but does not yet have AIDS. After the white blood cell is destroyed, the virus moves on to the next healthy cell.

In general, the two main types are classified as HIV-1 and HIV-2 [12], and while both types appear to have the same clinical manifestations, HIV-2 tends to have a lower transmission rate upon effective contact (direct contact between infectious and susceptible individuals) and a lower incubation period (the time period between infection and clinical symptoms) [13-15]. HIV-2 is rarely found outside of West Africa which prompts the public to imply HIV-1 when talking about HIV in public literature worldwide [16]. HIV-1 is further divided into groups based on their close phylogenetic association with the Simian immunodeficiency virus (SIV) which is also a retrovirus capable of infecting around 45 species of primates [17, 18]. HIV-1 subtypes include groups M, N, O, P, with Group M (which stands for Major) encompassing over 90% of HIV-1 infections worldwide and is believed to be closely related to the SIVcpz isolated from the common chimpanzee (Pan troglodytes) [10, 19]. Other groups of HIV-1 appear to be less prevalent and geographically limited centered in west-central Africa with groups O and P showing phylogenetic similarities with SIVgor isolated from the Western Gorilla (Gorilla gorilla) [20, 21]. Analysis of HIV-1 has led to further create subtypes within group M based on the geographic prevalence, with subtypes

Human immunodeficiency virus (HIV) is a virus that alters the immune system, making the population with HIV vulnerable to infections and diseases. HIV can be found in the body fluids of an infected person. The virus is passed from one person to another through blood-to-blood and sexual contact. HIV can be transmitted in many ways, such as vaginal, oral sex, anal sex, blood transfusion, and contaminated needles. Patients with HIV cannot clear to virus out of their bodies like most other viruses do. Once a patient is diagnosed with HIV, he will have it for life. According to the Center for Disease Control and Prevention (2015), HIV can stay in the body for a long time and attack ones T-cells or CD4 cells, which are the cells that are needed

The year of 1959 saw the first case of the sexually transmitted immune eating disease HIV .Human Immunodeficncy Virus or HIV was tested positive in a man from Congo. HIV is the attack by a disease of the body’s immune system essentially decaying it over time. With the simple symptoms of the common influenza HIV is a silent killer with more than 70 million infections globally and more than 35 million deaths (World Health Organisation, 2015). HIV can be transmitted in many different ways, as well as having multiple symptoms and signs. There is no current cure for HIV or AIDS but there are multiple biological options being made available. HIV destroys the immune system atrociously, allowing for the body to become weak and contract other diseases, most commonly AIDS (Acquired Immune Deficiency Syndrome) HIV and AIDS is one of the world’s mortiferous disease and has a world of biological beauty and intelligence behind it.

HIV is a member of the Retroviridae (retrovirus) family, its genus: Lentivirus. HIV is an

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.

Human Immunodeficiency Virus (HIV) and Acquired Immuno Deficiency Syndrome (AIDS) are complex diseases that are generally misunderstood and cast a stereotype of the people who are infected. A disease that is relatively new in comparisons to some diseases came to light as a public issue in the 1980’s and is now known around the world. HIV and AIDS attack the T-cells and CD4 cells of a person’s body which make them have symptoms similar to the flu. This disease is exactly what the name describes , an immune deficiency that lead to a lowered immune system cause a weakened body. HIV is a disease that continues to attack a person’s body and progresses until it turns in the final stage which was named AIDS. It is not a definitive progressive because not all cases of HIV will lead to AIDS, some will just maintain HIV for the rest of their life.
