Answer:
HIV harms the body by attacking the immune system, leaving the body defenseless.
Step-by-step explanation:
HIV (human immunodeficiency virus) attacks the white blood cells of the body, interfering with the body's ability to fight infection. Without treatment this disease can last for years and may ultimately result developing AIDS (acquired immunodeficiency syndrome). An AIDS patient has completely lost the ability to fight even the smallest infections. AIDS results in death.
