Due to demand and surging cases, Minnesota is expanding its free coronavirus testing options.  On Wednesday, Governor Walz said sites in Mankato, Moorhead, St. Cloud and Winona will be open an additional day.  This will increase capacity at each by about 500 tests.  The additional day will be added in Mankato and St. Cloud on October 15th as well as in Moorhead and Winona on October 17th.  Reports say COVID-19 testing at the sites was up about 10-percent last week compared to the week prior.
