Ms Von der Leyen, who attended a two-day summit of EU leaders in Brussels late last week, said she will be in quarantine until Tuesday morning.
Her isolation will keep her close to work, however. She has a small living quarters next to her office in the EU headquarters in Brussels.
Two weeks ago, EU Council president Charles Michel was forced to postpone a summit of EU leaders because he was quarantining.
Ms Von der Leyen took part last Tuesday in a special meeting of Portugal’s state council in the coastal town of Cascais, on the outskirts of Lisbon. State councillor Antonio Lobo Xavier tested positive for the virus on Sunday.
The meeting was attended physically by 15 of the 19 members of the president’s advisory body.
Portugal’s president, prime minister and the parliamentary president and five state councillors were tested on Sunday and were negative, media reported.
More tests are taking place on Monday.
