The move also extends a ban on travelers from Brazil, the United Kingdom, Ireland and 26 other European countries that had been set to expire Tuesday under a proclamation signed by former president Donald Trump shortly before he left office.
"With the pandemic worsening and more contagious variants spreading, this isn't the time to be lifting restrictions on international travel," White House spokeswoman Jen Psaki said during a Monday news conference. She said the move was part of the administration's "science-driven response" to the coronavirus.
The restrictions on travelers from South Africa are set to take effect Saturday.
In an interview on "CBS This Morning," Anthony Fauci, the government's top infectious-disease expert, said extending the ban and including South Africa "clearly will be helpful." Fauci said it is prudent to restrict travel of non-U. S. citizens.
"We have concern about the mutation that's in South Africa," he said. "It is clearly different and more ominous than the one in the U.K."
While some have questioned the value of travel bans, Fauci said one important difference this time around is that the ban dovetails with a requirement that all international travelers to the U.S. show proof of a negative coronavirus test.
Earlier this month, the Centers for Disease Control and Prevention warned that the variant of the coronavirus first seen in the United Kingdom would become the dominant strain in the U.S. within about two months. The South African variant, however, has not yet been identified in the U.S.
On Monday, Moderna said its vaccine will protect people from both the U.K. and South African variants of the virus. However, the vaccines' response to the South African variant was slightly diminished, officials said. As a result, the company said it work to develop a new vaccine that can be added to the current two-dose regimen.
The Biden administration is also taking steps to require travelers to quarantine after their arrival in the United States and to be tested a second time. Details on how those measures will be implemented are expected in the coming days.
Restrictions on travelers from 26 countries in Europe have been in place since mid-March, while Brazil was added to the list in May.
Under the ban, most non-U. S. citizens who have been in those countries in the past 14 days are barred from entering the United States. However, some exceptions are in place.
The extension of the ban comes as a new testing requirement for international travelers is set to take effect Tuesday.
Under the requirement announced earlier this month by the Centers for Disease Control and Prevention, all international travelers to the U.S. will be required to show proof of a negative coronavirus test before boarding a flight. PCR and antigen tests will be acceptable.
Those who refuse to be tested will not be allowed to fly. Travelers must be tested within three days before boarding their flights and airlines will be required to review travelers' documentation.
"As variants of the SARS-CoV-2 virus continue to emerge in countries around the world, there is growing evidence of increased transmissibility of some of these variants, as well as unknown health and vaccine implications," the CDC said in a statement. "Testing before and after travel is a critical layer to slow the introduction and spread of COVID-19 and emerging variants."
However, the agency said it would no longer issue waivers to countries with a limited ability to test travelers. The CDC had previously said it would allow carriers to apply for two-week waivers from the requirement.
"With the U.S. already in surge status, the testing requirement for all air passengers will help slow the spread of the virus as we work to vaccinate the American public," the agency said.
In addition to requiring proof of a negative test, Biden also has directed officials to explore the feasibility of requiring international travelers to quarantine or self-isolate once they arrive in the U.S.
The reinstatement of the ban is a blow to airlines that had hoped testing could replace bans and quarantines. Industry surveys have shown that people are more reluctant to travel if they must quarantine.
Since taking office, Biden has acted quickly to impose rules intended to reduce the spread of the virus as the administration seeks to ramp up efforts to vaccinate as many people as possible.
Last week, he signed an order mandating masks in airports and on many planes, trains, ships and intercity buses. The order followed one the president signed Wednesday, requiring that people wear masks on federal property.
