ELI5: Explain Like I'm 5

Body substance isolation

Okay kiddo, imagine you have a big container of Legos and you want to keep them safe and separate. You might sort them into different piles - blue ones go in the blue pile, red ones go in the red pile, and so on. This is kinda like what grown-ups do when they're trying to keep their bodies safe from yucky germs and diseases.

When someone is really sick, they might have these germs on their skin or in their blood or poop. So, doctors, nurses, and other helpers wear special clothes and gloves to keep their own skin safe. They might wear something like a big blue or green apron that covers them from neck to knees. They wear face masks to catch droplets of germs that might fly out of someone's mouth. They might even wear special goggles or glasses to protect their eyes!

Just like you wouldn't want to mix your blue and red Legos together, doctors and helpers don't want any of the sick person's body substances to touch their own skin, eyes, or mouth. That's why they call it "body substance isolation" - they're isolating, or separating, their own body from the sick person's body substances.

Once they're all covered up, they can help the sick person without getting sick themselves. They can give them medicine, change their bandages, or whatever needs doing. And when they're all done, they take off their gloves, apron, and mask, and throw them away safely. Then they wash their hands super-duper well to get rid of any germs that might have snuck through.

So, that's what body substance isolation is all about - keeping the sick person's germs away from the doctor's or nurse's skin, eyes, and mouth, so they don't get sick too. Easy peasy, right?
