Clinical Information

AIDS (acquired Immunodeficiency Syndrome) is characterized by changes in the populations of T-cell lymphocytes. In an infected individual, the virus causes depletion of helper T-cell, which leave the person susceptible to opportunistic infections and some malignancies. The virus that causes AIDS exists as two related types known as Human Immunodeficiency Virus Type 1 and Type 2 (HIV-1 and HIV-2). The presence of HIV first elicits the secretion of p24 antigen during acute infection followed by the production of specific antibodies to either HIV-1 or HIV-2.
