The United States said last week that it would upgrade the State Department's travel alerts to some of the highest levels of travel bans in relation to the spread of Corona19.

The area is Daegu and Gyeongbuk.

Vice President Mike Pence made the comments at a press conference with US President Donald Trump at the White House.

It took the highest level of action in three days following the upgrade from Phase 2 'Enhancement' to Phase 3 'Travel Inventory' last month.

This measure is for Americans traveling abroad.

The United States says it has raised travel alerts to four levels in parts of Italy where Corona 19 is rapidly spreading.
