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 that can make you sick. HIV (or human immunodeficiency virus) weakens your immune system, your bodyâs built-in defence against disease and illness. Anyone can be infected with HIV. You can have HIV without knowing it. You may not look or feel sick for years, but you can still pass the virus on to other people.
