However, repeated exposures can result in severe reactions. Swimmer’s itch usually resolves within 1–3 weeks without treatment. Short course of oral corticosteroid for a severe reaction.

Immediate towelling after exiting the water to reduce skin penetration of the parasites.To reduce the risk of cercariae on the skin: Use of chemical molluscicides such as copper sulphate or copper carbonate in small lakes to kill potentially infested snails.Reduce vegetation in high-risk areas to make the environment less favourable for the water snails.Feed birds with a drug to treat the parasite.rash reaction schistosomatidae skin swimmers swimmers swimming waterborne. To reduce parasite numbers in the environment: The image shows itchy, raised papules on the legs of a man. What is the treatment for swimmer’s itch? Preventative measures What is the differential diagnosis for swimmer’s itch? There is no widely available blood test to confirm an allergy to cercariae. Skin biopsies are not diagnostic but may be performed to exclude other causes of an itchy, blistering, or urticarial rash. Swimmer’s itch is suspected clinically based on the characteristics of the rash following bathing in infested waters. Secondary bacterial infection following scratching.Episodes become more severe with repeated exposures.What are the complications of swimmer’s itch? Outbreak of swimmer's itch in Denmark. Acta Derm Venereol. Cercariae may accidentally attach to human skin, penetrate the skin, die, and cause a local allergic reaction.Ĭredit: Images are from Tracz ES, Al-Jubury A, Buchmann K, Bygum A. Cercariae may penetrate the skin or are ingested by the aquatic bird/animal, develop into an adult worm, and the cycle starts again.

The miracidium enters the snail, elongates into a sporocyst, then matures into a cercaria which burrows out of the snail into the water. An egg hatches in the water to become a free-swimming miracidium in search of a specific snail species. The adult worm lives in a bird/animal, and the eggs are excreted via the intestines in the faeces. Schistosomes are parasitic flatworms with a lifecycle that involves aquatic birds (eg, ducks, geese, gulls, swans) or mammals (eg, beavers, muskrats), specific species of aquatic snails, and warm fresh or salt water. Swimmer’s itch is a disease of aquatic birds and humans are accidentally affected. However, it is only after repeated exposure to cercariae that the allergy develops and a rash eventuates. Young children are particularly susceptible as they tend to remain in shallow warm water where the snails are found in the highest numbers. Swimmer’s itch can affect anyone swimming in waters with infested snails.
