The new coronavirus strain that was first detected in the United Kingdom could already be circulating in the United States without notice, the U.S. Centers for Disease Control and Prevention said Tuesday.
“Ongoing travel between the United Kingdom and the United States, as well as the high prevalence of this variant among current UK infections, increase the likelihood of importation,” CDC said in a statement. “Given the small fraction of US infections that have been sequenced, the variant could already be in the United States without having been detected.”
The new variant is currently being referred to as “SARS-CoV-2 VUI 202012/01,” CDC said. It became prevalent across southeast England in November and reportedly accounts for 60% of recent infections in London, the agency said. CDC said it doesn’t know why the new strain of the virus emerged, but it could have been “by chance alone.”
“Alternatively, it may be emerging because it is better fit to spread in humans,” CDC said. “This rapid change from being a rare strain to becoming a common strain has concerned scientists in the UK, who are urgently evaluating the characteristics of the variant strain and of the illness that it causes.”
