The European Union is set to recommend halting nonessential travel from the U.S. because of the spread of Covid-19, diplomats said on Sunday. European officials have been considering the move for much of the last month, with the average U.S. infection rate now above that of the EU. The Slovenian presidency of the EU last week recommended removing the U.S. and five other countries from a list of countries allowed nonessential travel. A final decision is due on Monday.
