Swimmer’s itch reported in lake north of Phoenix

PHOENIX — Authorities said several cases of swimmer’s itch have been
reported in persons wading or swimming in Saguaro Lake northeast of Phoenix.

Health officials said swimmer’s itch is a rash caused by a tiny bird parasite
that can occur in natural bodies of water and have been reported in lakes
throughout Arizona.

It’s also known as cercarial dermatitis and lake itch.

People can be exposed when swimming or wading in shallow, marshy parts of
the water.

Symptoms consist of itchy reddish pimples and/or blisters that occur only on
portions of skin that are submerged in water and can persist for a few days up
to a few weeks.

Health officials said the rash goes away without treatment and symptoms are most
commonly treated with topical creams or lotions.
