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 infection means a person has been infected with the Human Immunodeficiency Virus (HIV). HIV damages the body's immune system, the system that fights infections. Without the immune system's protection, the body is defenseless against serious and potentially life-threatening diseases.
