A.I.D.S.Serious viral disease transmitted through sexual contact or blood, causing a profound alteration of vital status in the absence of immune reactions. The virus that causes AIDS produces an effect on lymphocytes (on all T4) that prevents the body fend off any infection. Currently, within the generic term "human immunodeficiency virus (HIV), there are viruses HTLV III and IV HLTV. The disease causes a drastic decrease the body's defenses, so conditions that occur by opportunistic pathogens, either virus, bacteria, fungi and protozoa. Transmission occurs only through sexual contact or by exposure to blood or other body fluids of a healthy person with an infected person, also through the placenta from an infected mother to fetus. The sharing of syringes between healthy and infected people, or transfusion of contaminated blood, act as transmitters of the disease. Among the HIV-infected must have antibodies in their blood to the virus (HIV) but no symptoms of the disease, while others have developed the disease with all its manifestations. Between these extremes there is a spectrum of varying degrees of clinical involvement. Acquired immunodeficiency syndrome, most referred to by its acronym AIDS or AIDS is a disease that affects humans infected by HIV. They say a person has AIDS when his body due to the immunodeficiency caused by HIV, is not capable of providing an adequate immune response against infections that afflict humans.
