Canyon creek,
I don’t know which case in MN you are talking about, but the lake my family camps at every memorial weekend “had a child infected with it”. It was reported on all the news channels. Mn Dept of health said it was a brain eating amoeba. The lake is around 8000 acres very popular lake with many beaches. After the news broke people stopped swimming, booking resorts and using the lake. The resort we go to almost had to shut down. Fast forward a few months, turns out it was not a brain eating amoeba, but meningitis I believe. There was hardly a mention in the news when the real cause was determined. All the public panic from our own dept of health was in-warranted. They never apologize and said they stand by there decision to warn the public of the threat. So imo you can worry about something that might happen to couple people a year or be like my family and enjoy swimming in the lake every year.
