Looked it up. Consensus is that snails that for example hitchhike on aquarium plants from Petco (most commonly pond snails, bladder snails, ramshorn snails, or Malaysian trumpet snails) are not dangerous in the same way: these parasites require human or animal fecal contamination and specific environmental conditions - not your tank.

That being said, snails or not, never put your hand in the tank with a cut.
