Any California resident who has suffered from a bout of the common cold may be able to generally describe what an illness is. Most may claim that an illness is a condition that affects a person's body due to the invasion of a bacterial or viral element into them. Different illnesses may cause individuals to suffer different symptoms, but in most cases the illnesses that individuals pick up in their daily lives resolve themselves without significant medical intervention.
