Infected snails then release a different kind of larvae known as cercariae, which is why swimmer’s itch is called cercarial dermatitis. These larvae swim around the water looking for a certain species of snail, and if they come into contact with the snail, the larvae will multiply and further develop. If those eggs reach water, they hatch and release tiny, microscopic larvae. The parasites lay eggs in the infected animal’s blood and then the eggs are passed through the infected animal’s poop.
