Florida and California, in particular, have significantly higher B.1.1.7 case counts. Since then, at the time of publication, nearly 1,000 B.1.1.7 infections have been identified in 34 states, according to CDC data. A Colorado man in his 20s with no reported travel history tested positive and recovered in isolation. The B.1.1.7 variant was first identified in the U.S. How many states have confirmed B.1.1.7 infections? in September 2020 and that it is associated with “more efficient and rapid transmission.” It’s now been detected in several countries, including the U.S. The CDC reports that B.1.1.7 is estimated to have emerged in the U.K. Weiss, as this is the piece of the coronavirus that latches onto human cells. Occasionally, the wrong set of combinations and mutations can occur.”ī.1.1.7 is notable for its number of mutations- six key mutations, to be exact- including some that directly involve the spike protein, which has generated “great interest,” says Dr. “Most of these are defective, don’t replicate very well, don’t carry on, and don’t matter. of Biostatistics & Epidemiology at the Rutgers School of Public Health previously told. Weiss, M.D., professor at both the Rutgers New Jersey Medical School and the Dept. ![]() “When SARS-CoV-2 replicates, errors get made-not infrequently,” Stanley H. They’re not always a cause for concern, but others are worth watching when they begin to spread rapidly. ![]() It’s important to remember that all viruses mutate. What is B.1.1.7 and where did it come from?Ĭoronavirus variants, like B.1.1.7, began to emerge after the original, dominant strain of SARS-CoV-2 began to mutate. Here’s what experts know about the B.1.1.7 coronavirus variant so far, and what you can do to protect yourself. scientists have analyzed, I’m pretty convinced that there is a degree of increase in seriousness of the actual infection, which we really have to keep an eye on.” “The data has not come out officially, but taking a look at the preliminary data that the U.K. The findings are “concerning,” Anthony Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases, said in a January 35 interview on Today. government’s science advisory group found that there is a “realistic possibility” that a B.1.1.7 infection “is associated with an increased risk of death” when compared to other strains of the virus. In a January report, researchers from the Centers for Disease Control and Prevention (CDC), warned that B.1.1.7 could become the dominant strain of SARS-CoV-2, the novel coronavirus that causes COVID-19, by March. is on a similar trajectory as other countries where B.1.1.7 rapidly became the dominant SARS-CoV-2 variant, requiring immediate and decisive action,” the researchers wrote. every nine days, with an increased transmission rate of up to 45%. The variant, B.1.1.7, has been detected in at least 34 states so far and is expected to continue circulating.Ī new preprint study estimates that cases of the variant are doubling in the U.S. A highly infectious coronavirus variant that was first detected in the U.K.
