Antihistamines may stimulate the nervous system, causing hyperactivity Antihistamines may make young children sleepy. For children, consult your health care provider such as your local pharmacist, family doctor or HealthLink BC. There are some steps you can take that may reduce some of the itchiness. Check with your health care provider about what treatment is right for you.
People become more sensitive to the larvae and develop stronger responses each time. The reaction may last from 2 to 5 days and symptoms can last as long as 2 weeks. How long do the symptoms last?Ī rash may appear within 12 hours after infection. As these red spots grow, the tingling feeling becomes a strong itch. Small, pin sized red spots will appear, which grow into larger red rashes within several hours. Symptoms tend to be worse after repeat exposure.Īs you start to dry off and the larvae start to burrow into your skin, you may feel a tingling sensation. The severity of your symptoms will depend on how many larvae get on to your skin, and how sensitive you are to them.

Scratching can cause severe pain and swelling or cause your skin to become infected. Symptoms can range from a mild irritation to a very severe, itchy red rash. However, showering will not remove any larvae that have already burrowed under your skin If possible, have a shower and dry off right away. Dry yourself off with a towel as soon as you come out of the water.See HealthLinkBC File #39 Safety Tips for Swimmers or contact the Lifesaving Society at for more information on swimming safety and drowning prevention Make sure these structures are approved for swimming and do not dive into unknown waters. Use a pier or dock to enter the water to help reduce your risk of exposure, as there may be more larvae near the shore.There may be more snails and larvae around aquatic plants If you are unsure about the water, avoid areas with lots of weed growth. Not all beaches have signage for swimmer’s itch. Check for warning signs at public beaches, lakes and picnic areas for notices stating that swimmer’s itch may be present.Speak with other visitors to the area, local health officers or parks representatives about the water condition before getting in any lake, pond or beach.However, there are certain precautions you can take: There is no sure way to avoid swimmer’s itch entirely unless you avoid water bodies. Younger children’s skin can be more sensitive than the skin of an adult.They usually play by the shore where the presence of schistosomes and their larvae is higher.They are constantly getting wet without thoroughly drying off.Young children who wade and splash in shallow water bodies may be at higher risk because:
Who has a higher risk of getting swimmer’s itch? Their larvae are more likely to be found floating near the surface in shallow water along the shores of fresh waters and coastal beaches.Ĭases of swimmer’s itch have been reported across Canada, including in B.C., and the northern United States. Schistosomes are found in many lakes, ponds and coastal waters in British Columbia, usually in the warm summer months. Swimmer’s itch cannot be spread from person to person. It is the reaction to these tiny parasitic larvae under the skin that causes swimmer’s itch. Since the larvae cannot survive in humans they will die almost immediately. If schistosome larvae are present in a body of water and you are in that water (swimming or wading) there is a chance that one or more larvae will burrow under your skin. During their life cycle, schistosome larvae (called cercariae) leave their snail host and swim near the surface of the water, looking for bird and mammal hosts. Schistosomes spend their life cycle as parasites in the bodies of water snails and in the blood stream of aquatic mammals, ducks or other waterfowl. Swimmer's itch is a skin rash caused by an allergic reaction to small worm-like parasites called schistosomes (shiss-toe-soams).
