Great progress was made in the U.
Centers for Disease Control and Prevention CDC reported a small grouping of Pneumocystis carinii pneumonia now classified as Pneumocystis jiroveci pneumonia cases in five gay men in Los Angeles, California. Although there are treatments for AIDS, there is no cure, nor a vaccine.
The virus, which can remain latent for up to 10 years, is the underlying cause of AIDS. Originally thought to have been transferred through sexual intercourse with those primates, epidemiologists theorize the disease actually spread when hunters came into blood contact with primates infected with SIV, which is the form HIV takes in infected sub-Saharan monkeys.
AIDS patients contract opportunistic infections through viruses or bacteria that cause such diseases as Kaposi Sarcoma, tuberculosis, and a host of unusual infections and cancers. Those with HIV who did not exhibit symptomatic diseases that the U.
The decrease in the number of those cells that serve as "middlemen" in the immune response, results in a weakened immune system that is more susceptible to immunodeficiency diseases. Although only a small number of Helper T-Cells are actually infected with HIV at any given time, researchers have been able to detect an ongoing cycle of death and infection of new target cells during the course of the disease.
Antiretroviral drug therapies with protease inhibitors, which reduce HIV in the blood and increase the number of Helper T-Cells the immune system needs to fight off infection, are taken in conjunction with other drugs to slow the progression to AIDS.
The multi-drug therapy approach has led to a percent drop in the number of people susceptible to opportunistic infections, or those who have died from AIDS.
Initially found almost exclusively in homosexual men and injection drug users, the overwhelming majority were males. By30 percent of new HIV infections in the U. They also attributed 23 percent of the U.
AIDS was the fifth leading cause of death among to year-old women in the U.
It has been determined that the transference of HIV is caused through anal, vaginal, or oral sex; blood transfusions; the use of contaminated needles in a health care setting and through drug injection; or from mother to child during pregnancy, childbirth and breastfeeding.
In Africa, it also is known to be transmitted during child circumcision with an instrument tainted with the HIV virus. Initially, HIV was found exclusively in sexually active heterosexuals in Africa. Their research also indicates its entrance date was actually aroundwhich does not coincide with the Dugas introduction story that appeared in And the Band Played On, written by San Francisco Chronicle reporter Randy Shilts.
The first known case of HIV was found in a person who died in the Congo in First thought to have only affected the male homosexual population, the term GRID or Gay-related Immunodeficiency Disease was originally proposed for the syndrome.
Instead, a less controversial and more neutral term called AIDS was adopted.
Early reports of unusual infections and cancers in otherwise healthy young homosexual men began to surface in San Francisco, Californiaand New York City in Findings of an atypical pneumonia and a cancer in homosexual men — previously found only in elderly Mediterranean men — was the subject of the first report of its kind in the Morbidity and Mortality Weekly Report.For a short time, the new disease was called gay-related immunodeficiency syndrome (GRIDS), but by September of , the CDC had published a case definition, using the current designation of acquired immune deficiency syndrome (AIDS) in print, and it was rapidly adopted by researchers.
AIDS Definition Acquired immune deficiency syndrome (AIDS) is an infectious disease caused by the human immunodeficiency virus (HIV). There are two variants of the HIV virus, HIV-1 and HIV-2, both of which ultimately cause AIDS.
Introduction. The AIDS epidemic in the United States officially began on June 18, , when the U.S. Centers for Disease Control and Prevention (CDC) reported a small grouping of Pneumocystis carinii pneumonia (now classified as Pneumocystis jiroveci pneumonia) cases in five gay men in Los Angeles, tranceformingnlp.comered to be a pandemic, Acquired Immunodeficiency Syndrome (AIDS) claimed.
AIDS: AIDS (acquired immunodeficiency syndrome), transmissible disease of the immune system caused by the human immunodeficiency virus (HIV).
HIV slowly attacks and destroys the immune system, leaving an individual vulnerable to a variety of other infections . In moderate doses caffeine has mainly positive effects for most people. But it increases production of cortisol, which can lead to health problems including anxiety, weight gain and heart disease.
