Yes. Hardmode corruption spreads through grass, stone, sand, and mud. It also spreads faster and across gaps (up to 2 blocks wide, like hallow). You're going to have to get underground and quarantine the deep corruption unless you want literally your entire underground that isn't hallow to be corruption.
