HIV is contracted by body fluid contact. It initially infects macrophages, T cells and antigen-presenting dendritic cells in the bloodstream. After several weeks, the humoral immune system is triggered by the massive amount of HIV phages produced by infected cells. Antibodies bind to HIV and phagocytes begin removing the resulting complexes, causing a brief decrease in HIV in the blood.
