What the University of Texas study said
Researchers at the University of Texas at Austin COVID-19 Modeling Consortium found the contagious COVID-19 variant originally discovered in the United Kingdom in December 2020 was already in the United States in October 2020.
- The findings were published in the journal Emerging Infectious Diseases.
The researchers said the coronavirus variant B117 went undetected throughout the entire world when scientists discovered it.
Lauren Ancel Meyers, the director of the COVID-19 Modeling Consortium at the University of Texas at Austin, said in a statement that the discovery of the U.K. variant came too late.
- “By the time we learned about the U.K. variant in December, it was already silently spreading across the globe,” she said. “We estimate that the B117 variant probably arrived in the U.S. by October of 2020, two months before we knew it existed.”

The researchers analyzed data from 15 countries to see what the chances were that travelers from the U.K. brought the variant to those 15 countries. The study found that the variants likely came between Sept. 22, 2020, and Dec. 7, 2020.
- The scientists predicted that the virus likely came to the U.S. by mid-October.
Concerns over U.K. variant
In February, experts worried the U.K. coronavirus variant would become the most dominant strain in the world, per BBC News.
