How the wildlife trade boosts the chance of a disease jumping from animals?

The wildlife trade is like a big party where animals from all over the world meet, and sometimes bring diseases with them.

Imagine you're at a playground, and kids from different classes come to play together. At first, it's fun, but if one kid has a cold and sneezes near others, soon more kids might catch that cold too. That’s what happens in the wildlife trade: animals are moved around, sometimes from far away, and they can carry diseases with them.

When wildlife traders move animals from one place to another, it's like moving kids from different classes into a new playground. These animals might not know each other, but now they're living together in the same cage or forest. If one of them has a disease, maybe something that only affects bats, for example, and the others are pigs or chickens, the disease might not hurt them at first.

But if the animals keep meeting new friends from other places, like at different markets or in new homes, that disease can spread more easily. It's kind of like when a cold goes around your class, it starts with one kid and then affects many others!

That’s how the wildlife trade gives diseases a jumping chance to move from animals into people, or even from one animal to another!
