How does HIV work?
The World Vision School Programme explains how HIV works.
Your body is protected by an immune system made up of white blood cells. White blood cells help fight disease and germs. HIV is a very strong germ that attacks the white blood cells themselves. After a long struggle, lasting years, HIV kills most of the white blood cells, leaving the body unprotected. That’s when infections set in and AIDS develops. AIDS is short for Acquired Immune Deficiency Syndrome; HIV is the Human Immunodeficiency Virus that causes AIDS.
