European land snails become hosts for the worm when they eat their eggs in animal faeces. These then hatch in their gut to produce 'sporocyst' larvae. Each sporocyst produces up to 4,000 tadpole-shaped larval worms an hour, known as cercariae. 18 окт. 2002 г.
Can you get worms from snails?

Can you get sick from playing with snails?

Are snails harmful to humans?
Freshwater snails carry a parasitic disease called schistosomiasis, which infects nearly 250 million people, mostly in Asia, Africa and South America. “It's one of the world's most deadly parasites,” says Susanne Sokolow, a disease ecologist at Stanford University's Hopkins Marine Station.
