The three agents worked p.m. shifts at checkpoint B in the airport's Terminal B during their most recent days at work, according to the TSA.
The three agents last worked Feb. 21, Feb. 26 and March 2, respectively, and two were stationed at the checkpoint's X-ray machines, scanning luggage and performing patdowns as needed.

The agency did not confirm how many agents and air passengers may have been exposed to the virus during their shifts.
