The employee, who was not identified, works at Orlando International Airport in Florida, and received the positive result earlier Saturday, FOX 35 of Orlando reported.
The officer is at home resting and will remain there until cleared by a doctor, a TSA spokesperson told the station.
As a precaution, an unspecified number of other TSA officers who worked closely with the stricken employee have been advised to stay home as well for 14 days to monitor their own conditions, according to FOX 35.
It was not immediately clear how closely the officer with the virus had come into contact with travelers at the airport.
“Enhanced cleaning” of all areas where the employee worked was done after the officer was diagnosed, the TSA said in a statement.
The Orlando airport is the nation’s 10th busiest, with some 50 million travelers passing through each year. It accommodates flights from 35 passenger airlines and five cargo airlines, the Orlando Sentinel reported.
