Acquired Immunodeficiency Syndrome or Acquired Immune Deficiency Syndrome (AIDS abbreviated) is a collection of symptoms and infections (or: syndrome) arising out of damage to the human immune system caused by HIV infection, or infection of other viruses that attack similar to other species (SIV, FIV, etc.).Own virus called Human Immunodeficiency Virus (HIV for short) is the virus that weakens the immunity in the human body. People who are exposed to this virus will become susceptible to opportunistic infections or tumor prone. Although there has been handling that can slow the rate of progression of the virus, but this disease can not be cured completely.
HIV and similar viruses are generally transmitted through direct contact between the skin layer (mucous membrane) or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal, and breast milk. Transmission can occur through sexual intercourse (vaginal, anal, or oral), blood transfusion, contaminated hypodermic needles, between mother and infant during pregnancy, childbirth, or breastfeeding, as well as other forms of contact with body fluids.
Scientists generally think that AIDS originated from Sub-Saharan Africa. Now, AIDS has become a plague. AIDS has infected an estimated 38.6 million people around the world. On January 2006, UNAIDS in collaboration with the WHO estimate that AIDS has caused the deaths of 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 has claimed the cause of death by 2.4 to 3.3 million lives in 2005 alone, and more than 570,000 people of whom are children. One third of these deaths occur in Sub-Saharan Africa, thus slowing economic growth and destroy the power of human resources there. Antiretroviral treatment can actually reduce the mortality rate and severity of HIV infection, but access to treatment is not available in all countries.
Social penalties for people with HIV / AIDS, are generally more severe when compared with patients with other deadly diseases. Sometimes the social punishment is also tertimpakan to health workers or volunteers, are involved in caring for people living with HIV / AIDS (PLWHA).
