Four Fox Business employees have tested positive for the coronavirus, according to an announcement from the media giant on Saturday.

The employees all worked out of the Fox Business office in New York City.

According to a memo sent by Fox News Media CEO Suzanne Scott and president and executive editor Jay Wallace, those who work directly with the positive employees must self-quarantine for fourteen days from the last time they were in contact as a precaution.

“On the advice of medical professionals, we have now made the determination that this employee’s direct co-workers/team self-quarantine for 14 days since last contact,” the statement, obtained by the Hill, read.

“In addition to taking every necessary precaution and following every protocol, we are deep cleaning all areas this employee was in contact with, in addition to the daily sanitizing and disinfecting that has been performed several times a day throughout all key areas of the building.

On Friday, the network had announced that they would be removing two hours from their programming amid the pandemic. They also reported that Lou Dobbs is in self-quarantine “out of an abundance of precaution” after a staffer on his show tested positive for the virus.

A staffer at NBC News in NYC passed away from the virus earlier this week.
