The United States is now warning against travel to Israel and several European countries as the more contagious delta variant fuels coronavirus outbreaks mostly among the unvaccinated.

The State Department and Centers for Disease Control and Prevention issued new travel advisories Monday for Israel, Cyprus, Portugal and Spain, as well as Kyrgyzstan, citing surging case numbers in all five countries.

The warnings came as the White House also said it had no plans to lift broad restrictions on visitors from Britain, countries in Europe’s Schengen region and other nations such as Brazil, China, India and South Africa. Spain and Portugal have already reopened to U.S. travelers — and Canada said it would allow entry to vaccinated Americans beginning next month.

But, “given where we are today … with the delta variant, we will maintain existing travel restrictions at this point,” White House press secretary Jen Psaki said Monday.

Here are some significant developments:

  • European lawmakers and business groups voiced mounting criticism of continued U.S. restrictions on international travel. As vaccinated American tourists are traveling back and forth for their summer holidays in Paris or Rome, European allies or partners of the Biden administration are finding it increasingly difficult to defend the U.S. approach.
  • Officials in Tokyo reported a record for coronavirus infections Tuesday, registering 2,848 new cases, its highest daily count ever and four times the average at the end of June. Even as case numbers spiked in the city, however, the situation inside the Olympic bubble appeared to be much more under control.
  • After the president of Tajikistan’s sister died in the hospital, reportedly of covid-19, her three sons attacked and beat up the country’s health minister and a senior doctor, according to local media. The reports cast a rare spotlight on the sudden surge of cases in this Central Asian country that for a time denied it had any infections.
  • Fresh coronavirus outbreaks are forcing factory shutdowns in countries such as Vietnam and Bangladesh, aggravating supply chain disruptions that could leave some U.S. retailers with empty shelves as consumers begin their back-to-school shopping.
  • Iran, one of the pandemic’s hardest-hit nations, reported its largest single-day increase in new coronavirus cases Tuesday, recording nearly 35,000 infections and 357 deaths. The recent surge has been blamed on the more contagious delta variant. About 3 percent of the population is fully vaccinated, according to publicly available figures.
  • Chinese researchers found that antibodies produced by the Sinovac coronavirus vaccine fell below a key threshold about six months after the second dose, raising concerns about waning immunity as new variants spread.

The U.S. government, as it raised its travel advisories to the highest levels for Cyprus, Portugal and Spain, strongly urged U.S. residents to avoid all travel to those countries even if fully vaccinated. Similar warnings were issued for travel to Britain last week, as new cases soared and the government in London scrapped nearly all public health restrictions.

Because of the coronavirus situation in those countries, “even fully vaccinated travelers may be at risk for getting and spreading COVID-19 variants,” the CDC said.

For Israel, the West Bank and Gaza Strip, the CDC issued a slightly less severe Level 3 notice, “indicating a high level of COVID-19” in the country, and urged unvaccinated people to “avoid nonessential travel to Israel.”
