AIDS (Acquired Immune Deficiency Syndrome) is the final and most serious stage of HIV disease , which causes severe damage to the immune system. According to the Centers for Disease Control and Prevention, AIDS begins when a person with HIV infection has a CD4 cell count below 200. (CD4 is also called "T-cell", a type of immune cell.) AIDS is also defined by numerous opportunistic infections and cancers that occur in the presence of HIV infection.

Acquired immunodeficiency syndrome (AIDS) is the final and most serious stage of the disease caused by the human immunodeficiency virus. Symptoms begin when an HIV-positive person presents a CD4-cell (also called T cell, a type of immune cell) count below 200.

A person with HIV can look and feel perfectly healthy. But that person can give HIV to others as soon as he or she is infected with the virus.

Acquired immune deficiency syndrome (AIDS) is an infectious disease caused by the human immunodeficiency virus (HIV). AIDS is the advanced form of infection caused by HIV and typically only manifests itself after a long latency period after initial HIV infection.

Human immunodeficiency virus (HIV) is a retrovirus that causes acquired immune deficiency syndrome (AIDS) by infecting helper T cells of the immune system. The most common serotype, HIV-1, is distributed worldwide, while HIV-2 is primarily confined to West Africa.

|
Acquired immunodeficiency syndrome, or AIDS, is the final, life-threatening stage of infection with any of the human immunodeficiency viruses (HIV-1, its many subtypes, or HIV-2), which are transmitted from person to person sexually (including via anal, oral, and vaginal intercourse, both heterosexually and homosexually), through contact with blood (mainly via equipment used to inject illicit drugs and, rarely, via medical uses of blood), and perinatally (from mother to fetus or newborn during pregnancy, labor, and delivery, or after birth through breast-feeding). ORIGIN AND HISTORY HIV-1 and HIV-2 both appear to have been transmitted to humans from primates in Central and West Africa, probably to hunters or processors of carcasses of primates consumed as food (referred to as " bush meat " ).

|
|
HIV (human immunodeficiency virus) was identified in 1983 by the French scientist Luc Montagier and his staff at the Pasteur Institute in Paris. Ever since that discovery, scientists have been searching for ways to treat those infected with HIV, and to produce a vaccine to prevent its spread.

Anticoagulants are drugs used to prevent clot formation or to prevent a clot that has formed from enlarging. They inhibit clot formation by blocking the action of clotting factors or platelets.

Autoimmune disorders are conditions caused by an immune response against the body's own tissues.
|
|
Autoimmune disorders are conditions in which a person ' s immune system attacks the body ' s own cells, causing tissue destruction. Autoimmunity is accepted as the cause of a wide range of disorders, and it is suspected to be responsible for many more.

|
|
Diseases in which the immune system attacks the body ' s own healthy tissues, forming antibodies in an assault on mistakenly identified " foreign invaders. " Autoimmune disorders occur when the body ' s immune system loses its ability to recognize the differences between self and nonself tissues.

This condition involves losing blood. This can occur internally (when blood leaks from blood vessels inside the body), externally through a natural opening (such as the vagina , mouth, or rectum), or externally through a break in the skin.
|
|
Call 911 if you can’t stop the bleeding or the victim shows signs of shock.
|
|
|
Preventing Bleeding During ChemotherapyChemotherapy can make your blood less able to clot. This happens because the treatment reduces the number ofplatelets(clotting agents) in your blood.

Candidiasis is an infection caused by a species of the yeast Candida , usually Candida albicans . This is a common cause of vaginal infections in women.
|
|
Candidiasis (thrush, monilia infection) is caused by a fungus that most commonly infects the mouth (usually of infants or persons with weakened immune systems), or the vagina (yeast infection). Another form of candidiasis causes painful inflammation under the fingernails (paronychia).
|
|
Candidiasis is an infection caused by a species of the yeast Candida , usually the Candida albicans fungus. Candida is found on various parts of the bodies of almost all normal people but causes problems in only a few.

|
Oral thrush is a yeast infection that affects the mouth. Babies with thrush are often fussy and may have trouble feeding. Thrush is seldom serious in healthy children and adults.

Fungi are types of parasitic plants that include molds, mildew, and yeast. A fungal infection is an inflammatory condition in which fungi multiply and invade the skin, the digestive tract, the genitals, and other body tissues, particularly, the lungs and liver.
|
|
Fungal infections of the skin are among today ' s most common infectious diseases, and they occur worldwide. Superficial fungus infections fall into three broad categories: the dermatophytes (ringworm), tinea versicolor, and cutaneous candidiasis (yeast infection).

Graves' disease is an autoimmune disease -- one in which the immune system attacks certain tissues -- that causes overactivity of the thyroid gland ( hyperthyroidism ).
|
![]() |
Hypoparthyroidism is having too little parathyroid hormone , which causes abnormal blood levels of calcium and phosphorus.
|
|
Hypoparathyroidism is the result of a decrease in production of parathyroid hormones by the parathyroid glands located behind the thyroid glands in the neck. The result is a low level of calcium in the blood.

Myasthenia gravis is a neuromuscular disorder characterized by variable weakness of voluntary muscles, which often improves with rest and worsens with activity. The condition is caused by an abnormal immune response .
|
|
|
Myasthenia gravis (MG) is an autoimmune disease that causes muscle weakness. It affects the neuromuscular junction, interrupting the communication between nerve and muscle, and thereby causing weakness.
|
|
|
Myasthenia gravis is an autoimmune disease that causes muscle weakness. The name myasthenia gravis literally means "grave muscle weakness".

Myasthenia gravis is an autoimmune disease that causes muscle weakness. Myasthenia gravis (MG) affects the neuromuscular junction, interrupting the communication between nerve and muscle, and thereby causing weakness.
|
|
|
Myasthenia gravis (MG) is a chronic autoimmune disease characterized by fatigue and muscular weakness, especially in the face and neck, that results from a breakdown in the normal communication between nerves and muscles caused by the deficiency of acetylcholine at the neuromuscular (nerve-muscle) junctions. MG is the most common primary disorder of neuromuscular transmission.

Pernicious anemia is caused by a lack of intrinsic factor, a substance needed to absorb vitamin B-12 from the gastrointestinal tract. Vitamin B-12 is necessary for the formation of red blood cells. Anemia is a condition where red blood cells are not providing adequate oxygen to body tissues. There are many types and causes of anemia. (See the general article - anemia ) Pernicious anemia is a type of megaloblastic anemia .
|
|
|
Pernicious anemia is a disease in which the red blood cells are abnormally formed, due to an inability to absorb vitamin B 12 . True pernicious anemia refers specifically to a disorder of atrophied parietal cells leading to absent intrinsic factor, resulting in an inability to absorb B 12 .

Hypopituitarism is a condition caused by low levels of pituitary hormones.
|
|
Hypopituitarism is loss of function in an endocrine gland due to failure of the pituitary gland to secrete hormones which stimulate that gland ' s function. The pituitary gland is located at the base of the brain.
|
|
Hypopituitarism, also known as the underactivity of the pituitary gland (an endocrine gland), is loss of function in the pituitary and the failure to secrete hormones that affect many of the body ' s functions. The pea-sized pituitary gland is located at the base of the brain , and is attached (by a stalk) to the hypothalamus.
