Britton Deerfield Schools in Lenawee County are closed Friday due to a flu outbreak.
Superintendent Stacy Johnson said the outbreak hit the staff the hardest.
"Our students are affected but the adults seem to be taking the brunt of it," Johnson said. "We are spending the day and weekend, if necessary, cleaning and disinfecting the buildings to prepare for our learners on Monday."
Johnson said the district plans to have school Monday.
