The causes and effects of the acquired immune deficiency syndrome

Your doctor will give you a vaccine. Then they will test your blood for its response to the vaccine a few days or weeks later. How are immunodeficiency disorders treated? The treatment for each immunodeficiency disorder will depend on the specific conditions.

The causes and effects of the acquired immune deficiency syndrome

It is also defined by numerous opportunistic infections and cancers that occur in the presence of HIV infection. About 47 million people worldwide have been infected with HIV since the start of the epidemic.

The virus attacks the immune system and leaves the body vulnerable to a variety of life-threatening illnesses and cancers. Common bacteria, yeast, parasites, and viruses that ordinarily do not cause serious disease in people with fully functional immune systems can cause fatal illnesses in people with AIDS.

HIV has been found in saliva, tears, nervous system tissue, blood, semen including pre-seminal fluid, or "pre-cum"vaginal fluid, and breast milk. However, only blood, semen, vaginal secretions, and breast milk have been proven to transmit infection to others.

Transmission of the virus occurs: Through sexual contact -- including oral, vaginal, and anal sex. Through blood -- via blood transfusions now extremely rare in the U. S or needle sharing. From mother to child -- a pregnant woman can passively transmit the virus to her fetus, or a nursing mother can transmit it to her baby.

Other transmission methods are rare and include accidental needle injury, artificial insemination with donated semen, and through a donated organ. HIV infection is not spread by casual contact such as hugging and touchingby touching dishes, doorknobs, or toilet seats previously touched by a person infected with the virus, during participation in sports, or by mosquitoes.

This is why blood banks and organ donor programs screen donors, blood, and tissues thoroughly. Those at highest risk include homosexual or bisexual men engaging in unprotected sex, intravenous drug users who share needles, the sexual partners of those who participate in high-risk activities, infants born to mothers with HIV, and people who received blood transfusions or clotting products between and prior to standard screening for the virus in the blood.

People infected with HIV may have no symptoms for ten years or longer, but they can still transmit the infection to others during this symptom-free period. Meanwhile, their immune system gradually weakens until they develop AIDS.

However, there is a tiny group of patients who develop AIDS very slowly or never at all. These patients are called non-progressors and many seem to have a genetic difference which prevents the virus from attaching to certain immune receptors. The symptoms of AIDS are primarily the result of infections that do not normally develop in individuals with healthy immune systems.

These are called "opportunistic infections. Common symptoms are fevers, sweats particularly at nightswollen glands, chills, weakness, and weight loss.

See the signs and tests section below for a list of common opportunistic infections and major symptoms associated with them. Initial infection may produce no symptoms. However, some people develop what feels like a "flu" about two weeks after contracting the virus.

Many other illnesses and corresponding symptoms may develop in addition to those listed here. Mycobacterium Avium -- a blood infection by a bacterium related to tuberculosis Cytomegalovirus infection -- a viral infection that can affect almost any organ system, especially the eyes In addition to the CD4 lymphocyte count, chest X-rays, Pap smears, and other tests are useful in managing HIV disease.

Gay men who engage in receptive anal sex may wish to consider anal Pap smears to detect potential cancers. There is no cure for AIDS at this time. However, several treatments are available that can delay the progression of disease for many years and improve the quality of life of those who have developed symptoms.

Antiviral therapy suppresses the replication of the HIV virus in the body. A combination of several antiretroviral agents, termed Highly Active Anti-Retroviral Therapy HAARThas been highly effective in reducing the number of HIV particles in the blood stream as measured by a blood test called the viral load.

This can help the immune system bounce back for a while and improve T-cell counts.

Human Immunodeficiency Virus And Acquired Immune Deficiency Syndrome - What You Need to Know

However, HIV tends to become resistant in patients who do not take their medications every day. Genetic tests are now available to determine whether the virus is resistant to a particular drug -- these may be useful in determining the best drug combination and adjusting it if it starts to fail.

Different combinations of medications are tried to attempt to reduce viral load. This is often not successful, unfortunately, and the patient will usually develop AIDS and its complications.

HAART is a collection of different medications, each with its own side effect profile.The first cases of the acquired immune deficiency syndrome (AIDS) were reported in but it is now clear that cases of the disease had been occurring unrecognized for at least 4 years before its identification.

The disease is characterized by a susceptibility to infection with opportunistic pathogens or by the occurrence of an aggressive form of Kaposi's sarcoma or B-cell lymphoma.

The human immunodeficiency virus (HIV) which causes acquired immune deficiency syndrome (AIDS) has brought about a global epidemic of massive proportions. HIV is a retrovirus and also the term often applied to the infection before the deterioration of the immune .

HIV stands for human immunodeficiency alphabetnyc.com 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 alphabetnyc.com once you get HIV, you have it for life.

What Are Immune Deficiency Disorders? Human immunodeficiency virus / acquired immune deficiency syndrome (HIV/AIDS). Causes of Erectile Dysfunction;. Human immunodeficiency virus (HIV) is the virus that causes AIDS. When a person becomes infected with HIV, the virus attacks and weakens the immune system.

Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV). [9] [10] [11] Following initial infection, a person may not notice any symptoms or may experience a brief period of influenza-like illness.
