The coronavirus variant first identified in the United Kingdom is now the most common strain of coronavirus in the United States, US Centers for Disease Control and Prevention Director Dr. Rochelle Walensky said Wednesday.
“Based on our most recent estimates from CDC surveillance, the B.1.1.7 variant is now the most common lineage circulating in the United States,” Walensky said at the White House COVID-19 Response Team briefing.
Studies have suggested that the UK variant is more contagious than the original strain, is possibly more dangerous and associated with a higher risk of death.
There are currently 16,275 confirmed cases of the B.1.1.7 variant in the United States, 据CDC称.
