It seems with all the flooding and high water there is a large increase in “duck itch” or “swimmer’s itch. I feel the public should be aptly warned. Here is an article from BC Health. http://www.healthlinkbc.ca/healthfiles/hfile52.stm
I have found that applications of waterproof SPF 60 will help.
If bitten, then applications of Lanacane will relieve the itch.
