President Joe Biden this week will impose a ban on most non-U.S. citizens entering the country who have recently been in South Africa in a bid to contain the spread of a new variant of COVID-19, according to U.S. public health officials.
The president will also reimpose an entry ban on nearly all non-U.S. travelers who have been in Brazil, the United Kingdom, Ireland, and 26 countries in Europe that allow travel across open borders, the sources told Reuters.
Former President Donald Trump directed on Jan. 18 that those restrictions on Brazil and Europe be lifted effective Tuesday, but Biden’s proclamation will rescind that decision.
Biden, who took office on Wednesday, is taking an aggressive approach to combating the spread of the virus in travel after Trump rejected mandates sought by U.S. health agencies.
Some health officials are concerned that current vaccines may not be effective against the South African variant, which also raises the prospect of re-infection.
The variant — also known as the 501Y.V2 variant — is 50% more infectious and has been detected in at least 20 countries. CDC officials said they would be open to adding additional countries to the list if needed.
The South African variant has not yet been found in the United States but at least 20 U.S. states have detected a UK variant known as B.1.1.7. Current vaccines appear effective against the UK mutations.
Centers for Disease Control and Prevention director (CDC) head Rochelle Walensky will sign a separate order Monday requiring masks on all airplanes, ferries, trains, subways, buses, taxis, and ride-share vehicles, officials said. The new requirements are set to take effect in the coming days, they said.
On Tuesday, new CDC rules take effect requiring all international air travelers 2 and older to present a negative coronavirus test taken within three calendar days of travel or proof of recovery from COVID-19 to enter the United States.
The CDC will not, as it said on Jan. 12, consider granting temporary waivers to airlines to exempt some travelers from countries with limited testing capacity. Numerous U.S. airlines last week had asked CDC for waivers, airline officials said.
But CDC officials said they would consider case-by-case humanitarian exemptions for some travelers if needed.
CDC officials noted 120 countries currently have mandatory COVID-19 testing requirements for international travel.
