Human Immunodeficiency Virus (HIV) Essay - 912 Words

Human Immunodeficiency Virus (HIV) Life History The human immunodeficiency virus (HIV) is an obligate intracellular parasite found exclusively in humans. It is responsible for weakening the immune system and leading to acquired immunodeficiency syndrome (AIDS). The first case of AIDS was diagnosed in the U.S. in 1981, and in 1984 it was first proven that HIV caused AIDS. There is currently a pandemic of HIV/AIDS, with the highest incidence rate in Sub-Saharan Africa and the lowest rates in Western Europe and North America, due to better healthcare. Transmission HIV is spread by sexual contact or blood-to-blood contact. HIV is most commonly spread by sexual contact, including vaginal, anal and oral sex. Another important mode†¦show more content†¦HIV primarily attacks CD4+ helper T cells by recognizing and binding the CD4 receptor on the surface of the T cells. It can sometimes invade monocytes and macrophages as well since they also have some CD4 receptors on their surfaces. Tumor necrosis factor alpha (TNF-a) and interleukin-6 (IL-6) are secreted at higher levels in infected individuals, and this may help activate the HIV proviruses (latent viruses). HIV has a high mutation rate during replication with the reverse transcriptase, which is why it is able to readily evade our immune response. Disease HIV causes the gradual weakening of the immune system which can culminate in acquired immunodeficiency syndrome (AIDS). About 2-4 weeks after initial infection with HIV there are generally flu-like symptoms that usually resolve themselves in a couple of weeks. The infected person then may go asymptomatic for a long time, often many years. The average development of AIDS in western nations, if untreated, is about 10-12 years after the initial infection of HIV. Persons with AIDS experience fatigue and excessive weight loss, along with fever, night sweats and swollen lymph nodes. The immune system is highly diminished in AIDS patients making them susceptible to many opportunistic diseases such as pneumonia caused by Pneumocystis carnii. AIDS patients can also develop neurological disorders and certain cancers associated such as Kaposi’s sarcoma andShow MoreRelatedHuman Immunodeficiency Virus ( Hiv )1359 Words   |  6 PagesThis paper explores the human immunodeficiency virus (H IV) as well as the simian immunodeficiency virus (SIV). The virus has infected two million adults and children by the year 2005 already. The virus continues to race around the world, and new HIV infections are at 50,000 per year (Martine Peeters, Matthieu Jung, Ahidjo Ayouba) (2013). The final outcome of the HIV infection is Acquired Immune Deficiency Syndrome (AIDS).

HIV, or Human Immunodeficiency Virus, is the virus that is spread through certain bodily fluids and can lead to AIDS (Acquired Immunodeficiency Syndrome). HIV attacks the immune system by destroying CD4+ T cells, which leaves the person infected with HIV vulnerable to other infections, diseases, and other complications.1 Once this virus is acquired, the human can ne ver fully rid itself of thisRead MoreHuman Immunodeficiency Virus ( Hiv )884 Words   |  4 Pages(2010), Human Immunodeficiency Virus (HIV) is a virus that affects the human immune system, leading to a chronic, progressive sickness that leaves people susceptible to opportunistic infections. When the body no longer can fight or resist infections, the condition is at this point referred to as AIDS, which means Acquired Immunodeficiency Syndrome. Averagely, it has been found to take more than ten years to develop from initial infection of HIV to AIDS.

More than 33.4 million people worldwide are infected with the HIV virus today. HIV stands for Human Immunodeficiency virus. HIV is a virus similar to that of the flu or common cold. The differentiating factor is that with the flu and cold, your body will eventually clear the virus out of your system, but with the HIV virus, the immune system cannot clear it. Getting HIV means you have it for life.

It is important to show compassion rather than judging that patient based on a virus. The hygienist plays an important role in making the patient feel comfortable and in a judgment free environment.

Though blood fulfills various functions to ensure our survival, it can also act as the mechanism through which we become diseased.

HIV is a fatal disease which stands for â€Å"Human Immunodeficiency Virus† it is a failure to the immune system to protect the body from any infections. This virus causes a condition called acquired immunodeficiency syndrome. When HIV is left untreated it leads to another disease called â€Å"AIDS†. It can occur in any age, race, sex or sexual orientation. The highest risk of contracting HIV is having unprotected sex and sha ring needles with others.

HIV first demanded notice in the early 1980s in the United States in homosexual men displaying illnesses like Pneumocystis carinii pneumonia and Kaposi’s sarcoma. The disease was soon observed in IV drug users, hemophiliacs, and blood transfusion recipients, but became publicized as a â€Å"gay disease,† nicknamed by the media as GRID, or Gay-RelatedRead MoreHuman Immunodeficiency Virus ( Hiv )1349 Words   |  6 Pages Human Immunodeficiency Virus (HIV) is a retro virus that causes AIDs by infecting the T Helper cells of the body’s immune system. The AIDS virus is the final stages of the HIV virus. HIV is a lentivirus genus, which is a subgroup of the retrovirus that causes the AIDS virus. Even with proper treatment, an infected person has a life expectancy of less than ten years.As the virus weakens t he human immune systems, this effectleaves the patient compromised and at risk to opportunistic infections
