Human immunodeficiency virus

Taxonomy Human immunodeficiency virus (HIV) in 1983, was an early report of a new disease discovered by both French virologist Luc Antoine Montagnier of the Pasteur Institute of Paris and Dr. Robert Gallo of the National Cancer Institute in Washington. The virus was at first named HTLV-III/LAV which is (human T-cell lymphotropic virus-type III/lymphadenopathy-associated virus) by an international scientific committee. The name was later changed to HIV Human immunodeficiency virus. Since the

HIV, the Human Immunodeficiency Virus, was first discovered by CDC in 1981 [3], then described as HTLV-III in 1983 and was later changed into its current name. Ever since its emergence, this virus has caused millions of infections throughout the world, with most of the cases originating in the African region [1]. This retrovirus has made it difficult in the past for scientists to treat it since it changes its RNA once inside the cell to DNA, through the enzyme reverse transcriptase, and keeps changing

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

1. Background HIV stands for Human Immunodeficiency Virus which attacks the immune system which makes it hard to fight off infection or disease. In the UK 100,000 people are currently living with HIV and one in five people in the UK have not yet been diagnosed. The virus is mostly transmitted through sexual activity but also by sharing needles and from mother to baby. This is transmitted either through pregnancy, birth or breastfeeding. The symptoms of HIV are flu-like symptoms and normally start

The Human Immunodeficiency Virus, HIV, is primarily a sexually transmitted infection. It can also be spread by contact with infected blood, most commonly IV drug users, or from mother to child during pregnancy, childbirth or breast-feeding. When HIV weakens the immune system HIV develops into AIDS. The start of HIV was said to come from a strain of DNA from Chimpanzee’s to contain polio. HIV/AIDS has become a widely spread virus that affects the human immune system. Africa has had the greatest

Picture this: a young child who is very skinny, ribs and all other bones are showing through the skin, they are born with HIV. it then leads to AIDS, due to their parents. HIV is a Human Immunodeficiency Virus. If HIV is left untreated, it can lead to AIDS, which is an acquired Immunodeficiency Syndrome. In Nigeria, Africa millions of people have the disease of AIDS and HIV. There is not many treatment options or solutions for this serious issue that takes place all over the country. There are a

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

Human Immunodeficiency Virus (HIV) is a virus that infects the cells of human immune system, causing destruction and impairing the cellular functions. Progressive deterioration of the immune system at cellular level causes associated infection to undermine the immune system putting the patient at risk of opportunistic infections. Acquired Immunodeficiency Syndrome (AIDS) is the most advanced stage of HIV. AIDS is caused when HIV related cancers hit the immune system by 20 or more opportunistic infections

retroviruses existed in non-human primates, it was believed that human retroviruses did not exist. However, after the T-cell lymphtropic virus was isolated from a patient with cutaneous T-cell lymphoma, the human T-cell leukemia/lymphoma virus (HTLV) became the first human retrovirus discovered and marked the beginning of scientific milestones. Since the initial discovery of HTLV in 1980, there have been 7 HTLV subtypes that have been established, the Human immunodeficiency virus (HIV) was discovered and

Introduction Human Immunodeficiency Virus (HIV) is an infectious agent that causes Acquired Immune Deficiency Syndrome (AIDS) in which the immune system breaks down, but it can take up to 10 years for HIV to turn into AIDS. This disease destroys CD4+ T cells, which are essential in helping the body fight disease (CDC, 2003). HIV can also invade the central nervous system which can cause severe neurological problems. AIDS was first reported in the United States in 1981, and since 1981 over 750,000
