European health officials have called screenings and restrictions on travelers from China unjustified, a stark contrast to the growing number of countries calling for tougher measures.

Europeans have high levels of protection against COVID-19, and health systems on the continent can handle the current load of infections, the European Centre for Disease Prevention and Control said Thursday.

It was commenting in the wake of decisions by countries ranging from the U.S. to Italy and Japan to introduce COVID-19 tests for all travelers from China. Beijing’s recent move to scrap its strict "zero-COVID" policies has sparked a surge in infections in China, and worries elsewhere about new variants.

Italy’s plan to test arrivals from China followed its discovery that almost half of the passengers on two recent flights from the country were positive for COVID-19. It said Thursday that sequencing showed the strains were of the omicron variant.

So far, the European Commission has refrained from following Italy’s lead. It downplayed the risks, noting that omicron is already present in Europe and has "not significantly grown.”

"However, we remain vigilant and will be ready to use the emergency brake if necessary,” the commission added.

The ECDC echoed the commission. It said the strains circulating in China are already present in Europe and the potential for imported infections is low compared to the level of COVID-19 transmission already happening in the EU.

Officials are nonetheless closely monitoring the situation in China and are in regular contact with health officials there, it said.
