Mohave,
I hope your flu symptoms are not an amoeba infection. They are misdiagnosed as such and that is why that infection is so dangerous.
I clicked on your link and all you get is a web corkboard. I think if you fully research the data about these children you will find in both cases these children also swam at other locations before flu symptoms sent them to the hospital. That is why blame must be on the other locations too. Hope your symptoms do not send you there.
Get well soon !
