Traces of the novel coronavirus were found in water samples taken from Lake Superior beaches in Duluth, Minn., according to researchers with the University of Minnesota Medical School, Duluth campus.
Since July, researchers have collected water samples from eight different beaches in Duluth in an effort to better understand how the novel virus “acts in the water and whether it can spread there,” the Star Tribune reported. (The Centers for Disease Control and Prevention says there is “no evidence that SARS-CoV-2, the virus that causes COVID-19, can spread to people through water” at oceans, lakes and other natural bodies of water, as well as pools, water playgrounds and hot tubs.)
In September, the researchers found traces of SARS-Cov-2 for the first time in water samples from Park Point, the beach at E. 42nd Avenue, and Brighton Beach.
“The research team describes the detection level at 100 to 1,000 copies per liter or 10,000 times lower than levels observed in wastewater,” the researchers said, according to the Star Tribune.
