I am not a microbiologist Kitty, but I believe it is being caused by an unusual bloom of a certain kind of algae on the section of shoreline of Lake Erie that intakes the water supply for the area. Sort of like the red tide near Tampa.It says that it is caused by an excessive flow of nutrients that feeds the algae into the water of Lake Erie. I think that there are all kinds of algae and the red tide kind doesn't affect us...so I feel worried for the Toledo people and not worried about us.
Well not much. But I even wonder what happens to the poop of the Dr. brought here to be treated with the Ebola virus.
