HIV (Human Immunodeficiency Virus) Infection - Topic Overview. HIV (human immunodeficiency virus) is a virus that attacks the immune system, the body's natural defense system. Without a strong immune system, the body has trouble fighting off disease. Both the virus and the infection it causes are called HIV. White blood cells are an important part of the immune system.
HIV is a virus spread through certain body fluids that attacks the bodyâs immune system, specifically the CD4 cells, often called T cells. Over time, HIV can destroy so many of these cells that the body canât fight off infections and disease. These special cells help the immune system fight off infections.
