Rochester's School 29 will continue with remote learning until Thursday.
Superintendent Lesli Myers-Small says the decision came out of an abundance of care for the staff.
At least 8 staff members at the school tested positive for the coronavirus last week.
The district also confirmed a custodial staff member died.
Staff, students and families will be able to get tested for coronavirus tomorrow, at Wilson Foundation Academy from 11 a.m. to 3 p.m.
