Thurston County Public Health and Social Services have stated in a news release last week that the parasite that causes swimmer’s itch appears to be present in Long Lake.
Multiple reports were received from individuals who swam at Long Lake and appear to have swimmer’s itch. Additionally, swimmers at any freshwater lake need to be aware that the parasite may be present and that there are ways to avoid being infected by it.
Swimmer’s itch, also called cercarial dermatitis, appears as a skin rash caused by an allergic reaction to certain microscopic parasites that infect some birds and mammals.
These parasites are released from infected snails into fresh and saltwater, such as lakes, ponds and oceans. If the parasite comes into contact with a swimmer, it burrows into the skin, causing an allergic reaction and rash, according to the release.
Swimmer’s itch generally resolves on its own without lasting health effects. Common symptoms include tingling, burning or itching of the skin. The release advises individuals to avoid scratching the affected area, as this may lead to secondary infection. In cases of severe itching, a health care provider may recommend prescription-strength creams or lotions.
Ways to reduce the likelihood of getting swimmer’s itch include:
• Choose not to swim in areas where swimmer’s itch is a known problem or where signs have been posted warning of unsafe water.
• Choose not to swim near or wade in marshy areas where snails are commonly found.
• Towel dry or shower immediately after leaving the water.
• Apply water-proof sunscreen before entering the water to both protect from the sun and reduce the ability of the parasite to attach to the skin.
• Do not attract birds to areas where people are swimming.
