Swimmers at Boulder Beach in the Lake Mead National Recreation Area are reporting having developed a rash similar to poison ivy.
It turns out it's due to an unusually large population of waterfowl at the shoreline and in the water. The rash is likely swimmer's itch.
Swimmer's itch occurs when parasites present in some birds come into contact with human skin. The parasite produces eggs that are passed in the feces of infected birds, according to the Centers for Disease Control and Prevention.
Swimmer's itch can typically be treated with anti-itch lotion or corticosteroid cream. You should always dry off with a towel after swimming.
It appears most of the swimmers were affected this past weekend. While the beach is not closed, park rangers are monitoring the shoreline. If you see excess droppings in the water, it is advised that you stay out.
