Swimmer’s itch is a skin rash caused by an allergic reaction to certain microscopic parasites at their larval stage. These parasites are released byinfected snails in both fresh water and salt water, but more common in the former. The parasite’s favored hosts are typically birds or specific mammals, however, when the parasite comes in direct contact with a swimmer, it burrows in the epidermal layer of the skin, thus resulting to skin rash and allergic reaction. However, because humans are not suitable hosts, the parasites will soon die while still in the skin.Swimmer’s itch can occur anywhere in the world, but it is more common during the summer months. It cannot be passed from person to person. Swimmer’s itch is also called cercarial dermatitis.

  • Eggs land in the water and will eventually hatch, releasing the free-swimming microscopic larvae.
  • Larvae will swim in water in search of aquatic snail.
  • Once the snail is infected, it will multiply and develop.
