HIV is a virus spread through certain body fluids that attacks the body's immune system, specifically the CD4 cells, often called T cells. Over time, HIV can destroy so many of these cells that the body can't fight off infections and disease. These special cells help the immune system fight off infections. Untreated, HIV reduces the number of CD4 cells in the body. This damage to the immune system makes it harder and harder for the body to fight off infections and some other diseases.

It must be recognized that there is not a single vitamin D compound but that there is a family of compounds that exhibit vitamin D activity.
