President Joe BidenMonday’s statement by Mr. Johnson indicated that the U.S. will not impose travel restrictions in an effort to limit the spread and distribution of the omicron Covid-19 strain, which could lead to some stockpiling.

On Friday, stocks in the aerospace and aviation industries fell after several countries announced cases of the omicron variant. New travel restrictions were also implemented. Visitors from South Africa (where scientists reported it first), as well from Botswana Zimbabwe, Namibia and Lesotho were temporarily blocked by the U.S. starting Monday.

Biden indicated that travel restrictions will be based on how widespread the variant is, at a news conference about the variant.

He said, “I don’t anticipate that at the moment.” Biden said that he does not believe lockdowns should be necessary.

This new rule comes three weeks after strict U.S. travel regulations that barred foreigners entering from Brazil, India and South Africa during a pandemic were lifted. According to airline executives, bookings increased after the Administration set a date for lifting the restrictions that were in effect since the outbreak.
