Each week, we share the number of first-hand, confirmed positive staff and student cases of COVID-19, and the number of quarantines in Mason City Schools.  Reasons for quarantine could include:  travel, close contact with a positive case (within 6 feet for 15 minutes or more), or waiting on COVID-19 test results.  Quarantine does not include positive case isolations which is reflected in the number of confirmed, first-hand positive cases of COVID-19.
