Los Angeles school officials on Wednesday confirmed the first coronavirus outbreak in the district at Grant Elementary School in Hollywood, sending home an entire classroom of children.

“The cases are concentrated in a single classroom and Los Angeles Unified is fully cooperating with the Department of Public Health,” the district said in a statement. “The district has alerted all those potentially impacted and the quarantined class has been provided with instructional materials to continue their studies.”

An outbreak is defined as three more cases over 14 days that are likely linked to one another. Wednesday was the eighth day of classes in the nation’s second-largest school system.

On Tuesday at 10 p.m., the district updated its online dashboard to record the seven linked cases at Grant.
