Last time I swam in a freshwater lake was circa 1982 in Minnesota. Now they get these scary warnings in the summer, a real downer in a state known for its lake-cabin culture...

MDH: Since it's been hot, avoid going underwater or plug your nose when you're swimming

The Minnesota Department of Health (MDH) is warning swimmers that a "very rare" brain-eating amoeba may be present in Minnesota lakes.

MDH Director Kris Ehresmann told reporters in the COVID-19 media call Friday that because it's been so warm in Minnesota since the start of July, swimmers should assume the rare amoeba called Naegleria fowleri is present in the state's lakes and rivers so they should take the proper precautions.

Naegleria fowleri is an amoeba that's found around the world in warm freshwater and soil. Only in the past decade has the amoeba been found in the northern United States and, according to Ehresmann, typically only after prolonged stretches of hot weather (like Minnesota has been experiencing), which cause water temperatures to rise and water levels to drop.

The amoeba very rarely infects people, but when it does it happens while they're swimming or diving in warm lakes or rivers. It enters through a swimmer's nose and travels to their brain, where it destroys the brain tissue. It can cause a "very rare" but severe brain infection called primary amebic meningoencephalitis (PAM), which is often fatal, MDH's website states.
