All schools are closed Tuesday, March 10.

ATLANTA — A Fulton County Schools employee has tested positive for the COVID-19 coronavirus, the school system said in a release.

"Today, FCS was informed that we have an employee with a confirmed case of Coronavirus," Fulton County Schools said in the release. "Based on this concern, we’ve decided to enact immediate dismissal at the impacted schools."

In a press conference Tuesday afternoon district Superintendent Mike Looney said the teacher started feeling sick on March 6 at the school and called 911.

“The teacher felt ill at work. 911 was called. This particular teacher was transported from the school campus.” Looney said.

The sick teacher worked at two schools, Bear Creek Middle School in Fairburn and Woodland Middle School in East Point. Creekside High School was also released early because of it's close proximity to Bear Creek Middle School and because many families have students in both schools, the district said.

The district said it is in the process of providing the Department of Health with a list of students and staff members who the employee may have had contact with, so the health department can follow up.

All the extracurricular activities at all schools are also cancelled for Tuesday.

All Fulton County Schools and offices will be closed Tuesday, March 10 in order to clean and disinfect the facilities. More closures are imminent, according to a voicemail message the district sent to parents Monday afternoon. A decision on the length of closing and the next steps will be made by 5 p.m. Tuesday.
