@OP: Corruption spreads through the Jungle.

The best way to stop corruption is to build a 3-block-thick retainer as it says in the article. And don't forget that you can use Purification Powder to turn corruption back to normal biome (and you can use Vile Powder to turn the Hallow back to normal).
