However, it is only after repeated exposure to cercariae that the allergy develops and a rash eventuates. Young children are particularly susceptible as they tend to remain in shallow warm water where the snails are found in the highest numbers. "We spent most of our time out in the middle of the lake where it's really not an issue, so I'm not all the worried.Swimmer’s itch can affect anyone swimming in waters with infested snails.

"A lot of people aren't susceptible to it," Murray said. Not everyone who comes in contact with the parasites will be affected, according to research, because the blemishes they cause are the result of an allergic reaction. The parasite is present in lakes and reservoirs around the country, but no single state agency in Utah tracks the occurrence of swimmer's itch. Cases have also been reported at Sand Hollow Reservoir in Hurricane and at Wide Hollow Reservoir near Escalante, according to Utah State Parks spokeswoman Deena Loyola.
