Local athletic directors 'cautiously optimistic' about new school contact tracing guidelines and last updated 2021-05-07 17:01:35-04 ROCKFORD, Mich. â The Michigan Department of Health and Human Services (MDHHS) will no longer enforce the school quarantine guidelines that resulted in students who were in close contact with a COVID-19 positive person to stay home. Local athletic directors are reacting to Fridayâs news, but say they are cautiously optimistic. We are just weeks away from the end of the spring sports season, and high school senior athletes have been concerned, not necessarily about testing positive, but afraid of being contact traced due to sitting close to somebody in a classroom.
