Countries worldwide are scrambling to address the spread of the omicron variant and part of their response has included a range of travel restrictions.

The U.S. has restricted travel from a number of countries in Southern Africa. Similar restrictions have been made by countries in Europe and Asia despite the variant first being identified in Europe.
