Question

What can happen if the immune system does NOT recognize a germ that's invaded your body?

Answer 1

Answer:

When your immune system fails , you're left without any natural protection against illness. This leaves you open to “opportunistic infections”  sicknesses that can even come from things that ordinarily wouldn't harm you.

Answer 2

you could become sick and your immune system might start failing and your whole body could shut down from just that one germ.
