The agent that leads to the development of the acquired immunodeficiency syndrome (AIDS). Individuals infected with the virus have an increased risk of developing lymphoma. The lymphomas are of the B cell type and may involve the brain or be widespread at the time of occurrence. Patients carrying the virus become immunologically impaired and are susceptible to unusual infections that are caused by microbes that usually do not infect healthy persons. (See Opportunistic Infection)
a class of viruses that infect and destroy helper T cells of the immune system
The retrovirus that causes AIDS, acquired immune deficiency syndrome.
A virus that infects and destroys CD4 T cells in the immune system.
HIV is a retrovirus which leads to Acquired Immunodeficiency Disease Syndrome (AIDS) in humans. HIV destroys the body's natural defences against disease by multiplying in the cells sent by the immune system to destroy it, making infected individuals susceptible to a wide range of opportunistic infections. Many of these infections are not normally serious, but HIV gives them the opportunity to have a lethal impact.

(HIV) The retrovirus that attacks T-cells in the human immune system, destroying the body's defenses and allowing the development of AIDS.
The virus destroys cells in the immune system, which makes it difficult for the body to fight off infections; toxins, or poisons; and diseases. HIV causes AIDS, a late stage of the virus characterized by serious infections, malignancies and neurologic dysfunctions.
The retrovirus isolated and recognized as the etiologic (i.e., causing or contributing to the cause of a disease) agent of AIDS.
This is a retrovirus that causes acquired immune deficiency syndrome (AIDS), a disease that destroys the body's ability to protect itself from infection and disease. It is transmitted by the exchange of body fluids or blood transfusions.
The causative viral agent of AIDS.
(HIV) any of a group of retroviruses that infect and destroy helper T cells in the immune system to a degree diagnostic of AIDS (acquired immune deficiency syndrome).
A virus that attacks certain cells of the body’s immune system and causes acquired immunodeficiency syndrome (AIDS).
A virus that weakens several body systems and destroys the body's immune system, making it easier for life threatening opportunistic infections and cancers to invade the body.
A virus that reduces the immune system functioning in affected individuals and is linked to AIDS.
A retrovirus transmitted by sexual contact, blood and blood products, or by an infected mother to her foetus or newborn at birth. This infection usually results in AIDS.
(HIV) OR acquired immunodeficiency syndrome (AIDS). AIDS was first reported in 1981 in the United States and has since become a major epidemic, killing nearly 12 million people and infecting more than 30 million others worldwide. The disease is caused by HIV, a virus that destroys the body's ability to fight infections and certain cancers.
The virus responsible for AIDS. All blood donations are tested for HIV, and those that test positive are destroyed. Donors with confirmed positive results are permanently disqualified.
A nine kilobyte retrovirus of the lentivirus family, believed to be cytopathic of T and B lymphocytes and haematopoietic stem cells, and associated with two types of cancer, encephalopathy, and 26 opportunistic infections.
HIV, the cause of AIDS. HIV has also been called the human lymphotropic virus type III, the lymphadenopathy-associated virus and the lymphadenopathy virus. No matter what name is applied, it is a retrovirus. (A retrovirus has an RNA genome and a reverse transcriptase enzyme. Using the reverse transcriptase, the virus uses its RNA as a template for making complementary DNA which can integrate into the DNA of the host organism). Although the American research Robert Gallo at the National Institutes of Health believed he was the first to find HIV, it is now generally accepted that the French physician Luc Montagnier (1932-) and his team at the Pasteur Institute discovered HIV in 1983- 84. See the entire definition of Human immunodeficiency virus
A retrovirus that attacks helper T cells of the immune system and causes acquired immunodeficiency syndrome (AIDS); transmitted through sexual intercourse or contact with infected blood.
a slow-acting retrovirus of the lentivirus family, believed to be the sole or primary cause of AIDS. HIV is transmitted sexually, through blood or vertically (from mother to child). There are 2 known types: HIV-1 and HIV-2. (hiv)
the cause of HIV Disease and AIDS -- A retrovirus (lentivirus family) that attacks the immune system. Formerly called HTLV III and LAV. (hiv-1)
An infectious disease that destroys the immune system by attacking T helper cell.
the virus associated with AIDS. The Anti-HIV test for exposure to the AIDS virus detects antibodies to HIV. A positive result from the anti-HIV means that the person has been exposed to the AIDS virus, has developed antibodies to the virus and may be a carrier of the virus. All blood units that test positive are destroyed and the blood donor is permanently deferred from donating blood.
Human T-cell lymphotropic virus type III; a cytopathic retrovirus (subfamily Lentvirinae, family Retroviridae) that is about 100 nm in diameter, has a lipid envelope, and has a characteristic dense cylindrical nucleoid containing core proteins and genomic RNA; it is the etiologic agent of acquired immunodeficiency syndrome (AIDS). Formerly or also known as the lymphadenopathy virus (LAV) or the human T-cell lymphotropic virus type III (HTLV-III). Identified in 1984 by Luc Montagnier and colleagues. RNA; it is the etiologic agent of acquired immunodeficiency syndrome (AIDS).
A transmissible retrovirus that causes AIDS in humans. Two forms of HIV are now recognized: HIV-1, which causes most cases of AIDS in Europe, North and South America, and most parts of Africa; and HIV-2, which is chiefly found in West African patients. HIV-2, discovered in 1986, appears to be less virulent than HIV-1 and may also have a longer latency period.
a viral infection that currently has no cure. HIV is passed during sexual intercourse, as well as when HIV-infected needles are shared and from infected mother to infant. It is estimated that 600,000 to 900,000 people in the U.S. are infected with HIV. HIV attacks a person's immune system, leading him or her to be susceptible to a host of diseases and conditions, and eventually progress to Acquired Immunodeficiency Syndrome (AIDS).
A type of retrovirus (human immunodeficiency virus) that infects helper T cells of the immune system. It is responsible for various illnesses including the fatal illness acquired immunodeficiency syndrome (AIDS). Two strains have been identified. The most common serotype, HIV-1, is distributed worldwide, while HIV-2 is primarily confined to West Africa.
HIV is a virus that lives and reproduces in the human body. Over time, HIV destroys part of the immune system and renders it ineffective. When the immune system is sufficiently depleted it can no longer overcome infections, illnesses and some cancers. When a person contracts two HIV-related illnesses (or Opportunistic Infections) simultaneously they are usually given an AIDS diagnosis.
The etiologic agent that causes AIDS.
The retrovirus thought to cause AIDS. Many different strains of HIV have been isolated. Name and acronym selected by respected group of international scientists in 1986 to describe HTLV-III; LAV; and ARV.
HIV. The cause of acquired immunodeficiency syndrome (AIDS).
The virus that causes AIDS.
The infectious agent that causes acquired immune deficiency syndrome (AIDS).
Retrovirus that is associated with the onset of AIDS.
The retrovirus that weakens the immune system, particularly by causing the death of many CD4+ T cells which coordinate the immune system's response to intruders. After a number of years (typically 5 - 10), this weakening of the immune system leaves the body open to attack from opportunistic infections, eventually leading to the development of Acquired Immune Deficiency Syndrome (AIDS).
