Anyone up for a nice, refreshing, early-autumn swim on the Nevada side of Lake Mead? Well, steer clear of Boulder Beach, which has been infected with – ick – swimmer’s itch.
Rangers say that an above-normal waterfowl population may be to blame for the poison ivy-like rash that was reported by at least a dozen swimmers over the weekend.
Also known as schistosome cercarial dermatitis, swimmer’s itch is caused when flatworm parasites that are found in some birds burrow into human skin and cause an allergic reaction. In some areas of the country, it's also known as lake itch or duck itch.
“The symptoms include tingling, burning, itching, small reddish pimples and small blisters that can appear within 12 hours,” a park official told the Los Angeles Times.
