What are immune evasion on multiple fronts?

Immune evasion on multiple fronts is when germs hide or trick your body’s defenders so they can keep causing trouble.

Imagine you're playing hide and seek with your friends in a big house. Your job is to find them, but they’re really good at hiding, some go under the couch, others behind the fridge, and one even wears a costume that looks just like a chair! That makes it harder for you to catch them all.

Germs are like those sneaky friends, when your body tries to fight them off with its defenders, like white blood cells or antibodies, germs use different tricks to avoid being caught. Some of them might change their look so they’re not recognized anymore, others might hide inside the body’s own cells, and some even make it harder for the defenders to work together.

This is why sometimes you get sick more than once, the germs didn’t just run away, they used different ways to outsmart your body’s defenders.
