Marathon Swimming Rash

A rise in incidence of skin rash that has been associated with swimming at Carden’s Cove on Lake Superior has been reported to the Thunder Bay District Health Unit by doctors at Marathon Family Practice. Based on information received, the rash is being treated as “Swimmer’s Itch”.

Swimmer's itch is a temporary skin infection acquired by bathers who come in contact with tiny worms called miracidia. The worms originate from waterfowl and mammals whose faecal material contains the worm eggs. The eggs hatch in the water and begin swimming to find a host. The tiny worms accidentally mistake humans as a host, and penetrate our skin as the water droplets evaporate.

Conditions of high waterfowl populations and warm water temperatures often trigger the problem.

After the bather leaves the water they may experience a tingling sensation and red spots will appear at the sites of penetration. Several hours later, the victim will experience a distinct itching sensation and the red spots will enlarge to form separate bumps.

Symptoms will vary depending on the sensitivity of the individual and with the severity of the infestation.

People swimming in lakes and rivers are advised to take the following measures:

• avoiding bathing areas suspected of being contaminated
• vigorously and completely toweling dry any skin surfaces wet with suspected water (before the water evaporates); and
• applying 70% alcohol immediately to spots on skin if experiencing a tingling sensation after swimming.

If a recent swim at a local beach has resulted in the distinct itching, some relief can be had by:

• Taking a bath with ½ cup of baking soda
• Applying anti-itch creams or lotions (consult a pharmacist).
• Taking antihistamine medication (always consult with your physician or pharmacist before taking any medication).
