UK COVID Variant Now Spreading in US

It has been just three weeks since U.K. health officials announced discovery of a new strain of coronavirus had been detected in Kent and was rapidly spreading northeast toward London. The variant called B.1.1.7 was found to be far more contagious -- as much more as 70%. Almost immediately after it was detected, dozens of nations cut off travel from the U.K. Finally, after many countries had acted, the U.S. last week shut off travel from the U.K, but then quickly reversed its decision with the only requirement that U.S.-bound travelers must have tested negative within three days prior to departure.
