On Monday, NBC News' Blayne Alexander reported that a Transportation Security Administration officer working at Hartsfield-Jackson Atlanta International Airport has tested positive for coronavirus.

The officer was working in the international departures section of the airport, which is reportedly now shut down as airport officials disinfect it. In the meantime, the international arrivals area is being used for both arrivals and departures.

Atlanta's airport is the world's busiest since 2000 — in 2019, the airport served more than 300,000 passengers a day. It is the largest hub for Delta Air Lines, and a major international gateway to the United States.
