Another new Covid subvariant has been detected and is now spreading rapidly around the world - already making up a quarter of new cases in some countries. BF. 7, also known as BA. 5.2.1.7, is now making up 25% of cases in Belgium and 10% of cases in Denmark, France and Germany.
Dr Stuart Ray, vice chair of medicine for data integrity and analytics at Johns Hopkins’ Department of Medicine, told Fortune: "The same growth advantage in multiple countries makes it reasonable to think that BF. 7 is gaining a foothold."
He added: "It’s been a while since we went from Alpha to Beta to Gamma to Delta, then to Omicron. We may be complacent. This may be feeding into the notion that this is behind us.”
