Omicron Cases Continue Disrupting International Travel

First detected on November 11, 2021, in Botswana, Africa, the number of countries reporting cases of the SARS-CoV-2 virus variant known as Omicron in the EU/EEA continues to increase, confirmed the ECDC today.

The number of countries reporting Omicron cases continues to increase globally, with a total of 352 confirmed cases reported by 27 countries as of December 1, 2021, including 70 confirmed cases reported by 13 European Union and European Economic Area (EU/EEA) countries.

There are several uncertainties around Omicron in terms of transmissibility, severity, and immune escape potential.

Based on mathematical modeling conducted by ECDC, there are indications that Omicron could cause over half of all SARS-CoV-2 infections in the EU/EEA within the next few months.

Temporary travel-related measures should be carefully considered in light of the latest epidemiological situation.

Such measures might include the testing and quarantining of travelers who have recently returned from affected countries. In addition, public information around the emerging situation and the public health measures in place are essential to raise awareness and support their effective implementation.
