This comes as the US is witnessing a significant rise in COVID-19 cases.Washington:
The United States has warned Americans travelling abroad to make "contingency plans" as countries around the globe grapple with rising numbers of COVID-19 cases spurred by the omicron variant.
"US citizens who do choose to travel internationally should make contingency plans, as they may have to remain in a foreign country longer than originally planned, which will be at their own expense. The Department recommends international travel insurance with coverage for COVID-related trip cancellation and medical benefits," the US State Department said in a statement.
"International Travel Challenges During COVID-19 US citizens who choose to travel internationally should be aware that they may face unexpected challenges related to COVID-19 as they attempt to return to the United States or attempt to travel from one overseas location to another," the statement added.
The US State Department also noted that all air travellers aged two and older, are required to show documentation of a negative viral test result taken within one day of the flight's departure to the US, or documentation of recovery from COVID-19.
This issue underscores the seriousness with which US officials are approaching the new omicron variant, the spread of which has already caused staff shortages and reductions, The Hill reported.
