The map below displays markers to show where swimmer’s itch outbreaks have been reported in Canada. An outbreak, as we define it, and in accordance with local health authorities in Alberta, is when five or more swimmer’s itch reports have been received from the same lake in the same week.
Please note that these reports have been generated through the use of our online survey, found on the “Report Your Itch” tab. Some of these lakes we are able to investigate for the presence of the parasite that causes swimmer’s itch for confirmation purposes, but at most lakes we are unable to do this.
Click on the marker you are interested in on the map below for further detailed information.
There are no current known outbreaks.
