The Grey Bruce Health Unit has received reports of individuals suffering from swimmer’s itch.
The skin rash is caused by a common allergic reaction to certain microscopic parasites released from infected snails in fresh water such as lakes and ponds.
The parasite’s preferred host is a bird or mammal but it can burrow into the skin if it comes into contact with a swimmer, particularly if the water is left to evaporate after swimming.
Although humans are not suitable hosts and the parasites soon die, they may cause an allergic reaction and rash. The rash is not contagious.
Epson salt baths, cool compresses and calamine lotion can bring some relief from the itching, burning blisters.
Avoid marshy areas, and towel dry or shower after swimming.
