A new variant of COVID believed to have first surfaced in the U.K. was discovered in Colorado on Tuesday, with health officials confirming a man in his 20s with no travel history had contracted the disease.

While much is still unknown about the new strain, analysis conducted by authorities in the U.K suggests it is up to 70 percent more transmissible than other variants, playing a significant role in a surge in cases across London and the south east of England.
