Two cafeterias used by White House staff members were closed and contact tracing was conducted after an employee tested positive for the coronavirus, a Trump administration official said on Wednesday night.
The cafeterias are in the Eisenhower Executive Office Building and the New Executive Office Building, which are part of the White House complex and are next to the West Wing.
It was not immediately clear whether the employee was a cafeteria worker, and the White House did not say what kind of symptoms the person showed.
The White House notified employees about measures in an email and said that there was no need for them to self-quarantine, according to the official, who spoke on condition of anonymity because the person was not authorized to speak publicly about the situation.
The staff members were advised to monitor for symptoms of the virus and instructed to stay home if they felt sick, the official said.
The development came just hours after President Trump spoke at the White House daily briefing on the pandemic, which his administration resumed this week. Mr. Trump’s job approval ratings have sagged amid a surge in new cases across the South and the West.
After months of resisting calls for him to recommend that Americans wear masks, Mr. Trump finally did so this week. The president also acknowledged that the pandemic was likely to get worse before it gets better.
Mr. Trump and members of his administration are regularly tested for the virus, as are credentialed journalists who cover the White House. But it was not immediately clear what testing protocols were in place for employees in the executive office buildings in the complex.
Despite the rigorous precautionary measures, Mr. Trump’s administration has not been able to keep the virus at bay.
In May, a military aide who had contact with Mr. Trump tested positive for the virus, as did Katie Miller, the press secretary for Vice President Mike Pence.
This month, Mr. Pence postponed a planned trip to Arizona after Secret Service agents set to travel with him tested positive for the coronavirus or showed symptoms of having it. And also this month, Kimberly Guilfoyle, the former Fox News commentator who is dating Donald Trump Jr., contracted the virus.
