Most countries in the bloc do not require Americans to isolate upon arrival, but a few have kept quarantine requirements in place this summer, including, in some cases, for inoculated visitors.
Still, most vaccinated American tourists have been able to enjoy the beaches of Greece, Spain or Portugal, the Italian countryside or the streets of Amsterdam or Paris without hurdles, boosting a tourism industry that was closed to them last year.
In countries such as France, Greece and Spain, U.S. visitors make up the largest contingent of tourists from non-European countries. In others, such as Portugal, total spending by Americans is among the highest of any nationality.
But as the United States returns to a daily average of 100,000 Covid hospitalizations over the last week, the European Council has advised E.U. countries to keep their borders shut to nonessential travel by unvaccinated Americans, in the hope of containing the spread of the Delta variant. The seven-day average of U.S. Covid hospitalizations peaked in mid-January with nearly 140,000 people hospitalized, according to federal data.
One of the council’s criteria for lifting restrictions is that a country should have fewer than 75 coronavirus cases per 100,000 inhabitants over the past 14-day period, but the United States has a reported infection rate well above that threshold, according to data provided by the European Center for Disease Control. The United States is also classified as a red zone by the agency, the second-most risky color, after dark red.
