Acquired Immunodeficiency Syndrome or Acquired Immune Deficiency Syndrome (AIDS abbreviated) is a collection of symptoms and infections caused by the destruction of the human immune system caused by HIV infection, [1] or infection with other viruses that attack similar to other species (SIV, FIV, and others).
The virus called Human Immunodeficiency Virus (HIV for short) is the virus that lowers immunity in the human body. People who are infected with the virus would be vulnerable to any infection or tumor prone. Although there has been handling can slow the spread of the virus, but the disease is not completely curable.
HIV and the virus-like viruses are generally transmitted by direct contact between the skin layers (mucous membrane) or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid, and breast milk. [2] [3] Transmission can occur through sexual intercourse (vaginal, anal, or oral), blood transfusion, contaminated hypodermic needles, between mother and baby during pregnancy, childbirth, or breastfeeding, or other forms of contact with the body fluids.
Scientists have generally found that HIV originated in sub-Saharan Africa. [4] Today AIDS has become a disease. AIDS estimated 38.6 million people worldwide. [5] In January 2006, UNAIDS in collaboration with the WHO estimate that AIDS has killed more than 25 million people since it was first recognized on June 5, 1981. Thus, this disease is one of the deadliest plague in history. AIDS claimed to have caused the death of as many as 2.4 to 3.3 million in 2005 alone, and more than 570,000 of them are children. [5] A third of these deaths occur in Sub-Saharan Africa, retarding growth economy and destroy the power of their human resources. Antiretroviral treatment can actually reduce the death rate and severity of HIV infection, but access to treatment is not available in all countries. [6]
Social punishment for people affected by HIV / AIDS, are generally more severe when compared with other deadly disease. Sometimes the social penalties also helped the health worker or volunteer, involved in caring for people living with HIV / AIDS.
Transmission of HIV
New HIV reproduce themselves seem emerged as small dots (colored green) on the surface of lymphocytes after attacking cell; viewed with an electron microscope.
AIDS is the most severe form due to infection with HIV. HIV is a retrovirus that usually attacks the vital organs of the human immune system such as CD4 + T cells (a type of T cells), macrophages, and dendritic cells. HIV destroys CD4 + T cells directly and indirectly, whereas CD4 + T cells necessary for the immune system to function properly. If HIV has killed CD4 + T cells to shrink in number to less than 200 per microliter (mL) of blood, then the immunity at the cellular level will be lost, and the result is a condition called AIDS. Acute HIV infection will progress to clinically latent infection, and symptoms of early HIV infection and ultimately AIDS; were identified by examining the number of CD4 + T cells in the blood and the presence of certain infections.
Without antiretroviral therapy, median duration of progression of HIV infection to AIDS is nine to ten years, and the average survival time after an AIDS only about 9.2 months. [7] However, the rate of progression of the disease varies greatly in each person , from two weeks to 20 years. Many factors that influence it, such is the power of the body to defend against HIV (such as immune function) from an infected person. [8] [9] The parents generally have weaker immune systems than younger people, and thus more at risk of disease progression rapid. Less access to health care and the existence of other infections such as tuberculosis, can also accelerate the development of this disease. [7] [10] [11] Genetic Inheritance infected person also plays an important role. Some people are naturally resistant to multiple HIV variants. [12] HIV has some genetic variation and a variety of different forms, which will cause the rate of clinical disease progression varies as well. [13] [14] [15] highly active antiretroviral therapy will be able to extend the average time berkembangannya AIDS , and the average survival time of people with abilities.
