The senior department official, Peter Berkowitz, held face-to-face meetings the same day with British officials. He had similar meetings with French diplomats a few days later in Paris before flying back to the United States on a commercial airline — and then testing positive for the coronavirus.
Mr. Berkowitz’s trip two weeks ago to Budapest, London and Paris has angered other State Department employees who believed it was unnecessary. It has irritated foreign officials whom he may have exposed to the virus. And it has raised questions about the limits of in-person diplomacy during a pandemic — especially as cases are again skyrocketing across the United States and Europe.
State Department protocols generally call for diplomats who are showing symptoms of the virus — including repeated coughing — to quarantine until they can be tested. Then, if they test positive for Covid-19, they are expected to remain overseas until they test negative or, in extreme cases, can be brought back to the United States with a biomedical unit.
