The prevalence of bird schistosomes in snail host populations was significantly lower than that of other digenean species. In our research, lymnaeid snails were collected from several Polish lakes for two vegetation seasons. Since we have little understanding of the behavior of these parasites inside the human body, the monitoring of their invasion in snail host populations is highly recommended.
These parasites have developed a number of strategies to invade vertebrates.

have been identified as a causative agent of swimmers’ itch, a skin disease provoked by contact with these digenean trematodes in water.

Tingling, burning or itching of the skin, small reddish pimples, or small blisters.Children are more likely to develop swimmer’s itch because they tend to spend time in shallow water and they are less likely to towel dry themselves after leaving the water. Those swimming and/or water skiing in deeper water are less likely to come into contact with the parasite. The conditions in which snails thrive are gravelly shores with wave action, so the potential for snails and swimmer’s itch is everywhere around the lake. Who May Develop Swimmer’s Itch?Īnyone who swims or wades in water containing the parasite may be at risk. When the larvae are present in the lake they sometimes mistake us for hosts -which we are not - but they can burrow a tiny bit into our skin and cause an uncomfortable rash. Swimmer’s itch, also known as cercarial dermatitis, is an irritating yet harmless rash caused by the human body’s reaction to a microscopic parasite found in warm, shallow water. These parasites are the tiny larvae of blood flukes, which are hosted by aquatic birds and snails. Here are steps you can take to avoid developing the rash. A number of individuals are reporting that they have contracted “Swimmer’s Itch” after swimming in Copake Lake.
