What Is Human Immunodeficiency Virus? Essay

There have been 4,043 reported diagnosed cases of Human Immunodeficiency Virus infection (HIV) per 100,000 populations. Human Immunodeficiency Virus is a virus that attacks the body’s immune system. The Human Immunodeficiency Virus attacks a specific white blood cell called T- helper cells which are used to fight off infection. As the virus destroys the t- helper cells, it replicates, destroying the immune system of the individual. Individuals who have the Human Immunodeficiency Virus Infection will have to constantly take medication to suppress the spread of the disease. If left untreated it will become very difficult for the individual’s body to fight off the virus resulting in death.

Human immunodeficiency virus (HIV)/AIDS is a pandemic problem affecting global health. At the end of 2015, 36.7 million people were living with HIV/AIDS globally. The rate of incidence is more prevalent in Sub-Saharan Africa with almost 1 in every 24 adults living with HIV/AIDS. In the united states, HIV/AIDS is a diversified health problem affecting all sexes, ages and races and involving the transmission of multiple risk behavior. However, with the introduction of various prevention programs and antiretroviral drugs, the incidence of HIV/AIDS has reduced.

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].

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,

HIV/AIDs is a huge epidemic still plaguing society today. The lack of knowledge and technical advances has caused an increasing number of cases. It has made its way around the world since the 1940s, causing countries to join together in the fight against AIDs. With all the campaigning that has been done the numbers of cases continue to rise. Countries have separated the disease into three patterns to make it easier to distinguish the effects that AIDs has on different regions of the world. As well as what subtypes sprout from what areas. HIV/AIDs can be spread in many different ways. The future is still uncertain for the victims whom lives have been dramatically changed by this deadly disease.

HIV stands for (Human Immunodeficiency Virus). If not treated properly, it can be turned into a disease called AIDS (Acquired Immunodeficiency Syndrome). HIV affects the body's immune system, primarily targeting the T cells. In result of this, the human body is more vulnerable to get more infections

“Everyday the HIV/AIDS pandemic continues to kill three times as many people than died during the terrorist attacks of September 11, 2001” (Elbe 2006, p.119). The Human Immunodeficiency Virus (HIV) weakens the immune system by destroying the cells that fight disease and infection. In the final stages of the HIV infection, it can lead to the acquired immunodeficiency syndrome (AIDS). Not all people who are diagnosed with HIV progress to acquiring AIDS, although once you have been diagnosed with the HIV infection, you have it for life. HIV/AIDS have claimed the lives of more than 39 million people globally since the discovery (World Health Organisation 2014) with a majority of these cases being in sub-Saharan Africa.

HIV stands for Human Immunodeficiency virus. If the virus goes untreated it can lead to AIDS. AIDS stands for Acquired Immunodeficiency Syndrome. HIV attacks the body’s immune system such as the T cells. T cells help fight off infection. When it goes untreated, it decreases the number of T cells in a person’s body. This leads to AIDS, which is the last stage of HIV. AIDS occur when the immune system is severely damaged and you become more prone to infections. When the T cell count is lower than 200, then you’ve moved on to this stage. People who have AIDS usually live up to 3 years subsequently.

The human immunodeficiency virus gets its name by the sole species it affects and the characteristic damage it does to the body, which is also known as HIV. Viruses are notorious for the mode in which they reproduce; a virus enters the body, seizes the body’s cells, and uses it as a host. This is the only way for viruses to replicate. HIV takes over the body’s T cells, also known as CD4 cells, which are important to defend the body from various antigens. Normally, T cells would respond to infection and diseases by neutralizing, creating antibodies to fight off the antigen the next time it comes around, or lessen the effects it has on the body. Infections such as pneumonia that would make a regular person incredibly ill could be fatal to someone

HIV attacks the body’s immune system, by destroying CD4 cells also knows as T cells, that are a type of white blood cells that help the body immune system fight off infections. T cells have proteins that helps the HIV virus bind. If HIV is left untreated, it can reduce the numbers of infected CD4 cells in the body, making the person's more prone to infections ("CD4 Count, HIV, and AIDS: Test and Results -- What They Mean," n.d.). Over time, HIV can completely destroy these cells and the body can no longer fight off infectious disease. When the body begins losing its ability to fight infections and the CD4 cell

Diseases, infections, and viruses effect the population around the world each and every day. One of those viruses is the Human Immunodeficiency Virus, or better known as HIV. HIV is a virus that attacks the immune system, causing it to become weak and vulnerable. HIV can later on turn into AIDS, or Acquired Immune Deficiency Syndrome. There is currently no known cure for HIV or AIDS, but there are treatment plans available to help prolong HIV from turning into AIDS.

“HIV also known as human immunodeficiency virus is a virus that attacks the immune system, the body 's natural defense system.” When a person has a weak immune system as oppose to a strong immune system the body has a hard time fighting off the disease. The HIV virus and the infection that it causes is called HIV. White blood cells are an important part of the immune system. One of the major symptoms and by far the worst is when HIV infects and destroys certain white blood cells. If too many white blood cells are destroyed, the body can no longer defend itself against the virus or infection. The last part of HIV infection is AIDS. People with AIDS have a low number of white

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 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”).
