Who is Pathogen Spillover?

Pathogen spillover is when germs from animals jump to humans and start making them sick.

Imagine you're playing in a park with your dog, and you both get muddy. Then, later, you get a tummy ache, maybe the mud had some germs that came from your dog. That's kind of like pathogen spillover!

Germs on the Move

Sometimes, animals are full of germs that don’t bother them but can make humans very sick. For example, bats have a germ called Ebola, and when they get close to people, maybe by coughing or touching something, the germ can jump from bat to human.

How Germs Make the Jump

It's like sharing a toy with someone who has a cold: the germs go from one person to another. But with pathogen spillover, it’s more like when your dog sneezes on you, and then you get sick!

Sometimes people don’t even know they're playing with germs until they feel under the weather. That's why it's important to be careful around animals, or maybe just wash your hands after playing in the mud!
