Swimmer's itch is usually most prevalent in shallowĭownwind areas of lakes. Some common bird hosts include common mergansers, mallards, swans, and Middle when the parasite enters our skin instead of the birds. So how do humans fit into this picture? When the larval parasite leaves the snail, it then needs to enter a bird Hosts for the larval parasite stages and bird hosts for the adult parasite. Parasite species that cause swimmer's itch use aquatic snails as intermediate Sounds repulsive, but the parasite doesn't do any harm to humans besides causing Swimmer's itch is caused by a tiny parasite that enters Once you have had swimmer's itch, your skin may be more sensitive to it ![]() It can itch for a week or so and feel uncomfortable.

Snails carry the organism too, so if there are weeds or other debris near shore, there's a possibility that there are snails around also. Be sure to keep beaches clean of weeds and other debris that washes ashore. The organism drifts to shallow water near the shoreline, so it's best to avoid wading or playing in shallow water. If possible, swim from a raft or boat farther out in the water. Toweling off immediately after swimming helps avoid this scenario. The organism needs water to live, when water starts evaporating off the skin, it burrows in to survive. ![]() Stop feeding any geese or ducks near the dock. However, an important fact to consider is that the critter starts out in the intestinal lining of waterfowl, mostly ducks. The organism that causes swimmer's itch has a complicated life history. They can carry the adult form of the organism, so it is better if they aren't hanging around public beaches. Do not encourage waterfowl to hang around beaches. The DNR offers the following tips to minimize the likelihood of getting swimmer's itch: This behavior makes it easy for them to be moved around the lake, and tends to concentrate their numbers along the shoreline. The cercaria only lives for a day or so and typically inhabits the upper few inches of water, which increases its chances of coming into contact with a duck, its host. The life stage that causes swimmer's itch is called a "cercaria" which is an immature stage of a blood fluke common in waterfowl, according to the DNR. Much like poison ivy, the more times you come in contact with the organism that carries swimmer's itch, the more likely the chances are that you will get it. Each summer as lake water temperatures rise, some swimmers begin to get the itch - swimmer's itch, that is.Ī few reports have been made in the Park Rapids area already but there are no "hot spots," said Edie Evarts, Assistant Area Fisheries Supervisor for the Department of Natural Resources in Park Rapids.Īccording to the Department of Natural Resources, only 30-40 percent of people are sensitive to swimmer's itch. ![]()
