ATLANTA — Georgia’s governor says the reopening of some of the state’s schools amid the coronavirus outbreak has gone well except for photos shared on social media showing students crowded together in hallways.

“I think quite honestly this week went real well other than a couple of virtual photos,” Gov. Brian Kemp said at a news conference with the U.S. surgeon general on Monday.

Photos shared widely on social media last week showed hallways packed shoulder to shoulder with students at North Paulding High School northwest of Atlanta. School officials later announced that six students and three staff members had tested positive for the coronavirus, and that the school would be closed Monday and Tuesday while the building is disinfected.

In nearby Cherokee County, 12 students and two staff members from a dozen schools tested positive for the virus during their first week back. The Cherokee County system reported that more than 250 students with potential exposure had been sent home to quarantine for two weeks.

Cherokee County also drew attention because of online photos. Dozens of students at two of its high schools squeezed together for first-day-of-school senior photos. None wore masks.
