Nov. 24, 2021 — Countries across Europe are facing another surge in coronavirus cases, which could lead to another 700,000 deaths by March 1 if current trends continue, the WHO announced on Tuesday.

More than 1.5 million people have already died from COVID-19 in the 53 countries that make up the World Health Organization’s European region. That means the death toll could top 2.2 million by early 2022.

Europe “remains firmly in the grip of the COVID-19 pandemic,” the WHO said, noting that the coronavirus is the leading cause of death across Europe and Central Asia. Between now and March, intensive care units in 49 of the 53 countries will face “high or extreme stress.”

The WHO reported more than 2.4 million new cases across the region last week, which made up 67% of all COVID-19 cases worldwide during that time. Deaths increased to nearly 4,200 per day, doubling the 2,100 daily deaths reported at the end of September.

“As we approach the end of 2021, let’s do everything we can by getting vaccinated and taking personal protective measures to avoid the last resort of lockdowns and school closures,” Hans Kluge, WHO’s regional director for Europe, said in the WHO statement.

Some countries are putting strict measures into place again to contain the spread of the virus, which has sparked protests, according to The New York Times. On Monday, Austria returned to lockdown for at least 10 days, closing shops, restaurants, and holiday markets. The Netherlands also began a partial lockdown during the weekend, and Germany may announce new restrictions this week.

In addition, more countries are approving booster shots for fully vaccinated people, including France, Germany, and Greece, according to the BBC. More evidence is showing that vaccine protection is waning and breakthrough cases are becoming more common, according to the WHO, which encouraged countries to approve booster doses for vulnerable groups, health care workers, and people over age 60.

Europe and Central Asia face “a challenging winter ahead,” Kluge said. He called for a “vaccine plus” approach, which includes getting vaccinated, following physical distancing guidelines, and wearing masks.

Face masks reduce coronavirus transmission by 53%, the WHO said, which could prevent more than 160,000 deaths by March 1.

The U.S. State Department has responded to the European surge by adding Denmark and Germany to its “Do Not Travel” list, which is the highest-risk category for travel, according to The Washington Post.

The Level 4 designation means that both the CDC and State Department recommend against traveling to those countries, even if people are vaccinated. Other European countries were added to the Level 4 list last week, including the Czech Republic, Hungary, and Iceland.
