More contagious virus variant is found in Colorado
A case of the more contagious coronavirus variant first discovered in Britain was found in Colorado on Tuesday, Gov. Jared Polis said. It is the first confirmed case of the variant in the United States.
The variant was detected in a man in his 20s with no travel history, Polis said. The man was in isolation in Elbert County, southeast of Denver, he said.
“There is a lot we don’t know about this new COVID-19 variant, but scientists in the United Kingdom are warning the world that it is significantly more contagious,” Polis said in a statement. “The health and safety of Coloradans is our top priority and we will closely monitor this case, as well as all COVID-19 indicators, very closely.”
Scientists are worried about these variants but not surprised by them. It is normal for viruses to mutate, and most of the mutations of the coronavirus have proved minor.
“This should not be cause for panic,” said William Hanage, an epidemiologist at Harvard University.
“But it is cause to redouble our efforts at preventing the virus from getting the opportunity to spread.”
This month, British researchers observed that the variant was becoming more prevalent in parts of Britain. Their subsequent investigations suggest that
the variant — known as B.1.1.7 — spreads more readily than others.
Countries around the world have implemented stricter protocols for travelers entering from the United Kingdom. A new rule in the United States mandating that incoming travelers from the U.K. show proof of a negative coronavirus test upon entry went into effect Monday.
It’s not clear where B.1.1.7 arose. Britain has the biggest system for sequencing the genomes of coronaviruses, which may be why the variant was first found there. Cases of the variant have also been identified in France, Spain and other European nations, as well as Lebanon and Singapore. Health officials in Ontario, Canada, said Saturday that they had identified two cases of the variant in a couple with no known travel history or exposure.
The fact that the Colorado man identified Tuesday had no travel history raises the worrisome possibility that B.1.1.7 is already well-established in his community. “It didn’t teleport across the Atlantic,” Hanage said.
