Barely a week after Georgia reopened its public schools amid the ongoing COVID-19 pandemic, a school district north of Atlanta has ordered 925 students, teachers and staff to self-quarantine after dozens tested positive for the coronavirus. The district also announced the temporary closing of one of its hardest-hit high schools. Cherokee County School District Superintendent Brian Hightower said in a statement Tuesday that there had been 59 positive COVID-19 tests among students and staff since the Aug. 3 reopening. … At the end of Monday, about 300 of the school's 2,400 students, or 12.5%, were under quarantine, according to The Atlanta Journal-Constitution.
