A new study just confirmed that the COVID strain that originated in the U.K., called B.1.1.7, could be far deadlier for those infected by it, The Washington Post reports. According to NERVTAG researchers, this variant is 30 to 70 percent deadlier than previous virus strains. The study’s authors concluded that there is significant evidence that B.1.1.7 is “associated with an increased risk of hospitalization and death compared to infection” from other strains of the coronavirus.

While it was just recently confirmed that the U.K. variant is deadlier—a fear Prime Minister Boris Johnson shared a month ago—experts have long suspected that the U.K. strain is more contagious than others, as well. Researchers from the London School of Hygiene and Tropical Medicine estimate that the variant is 43 to 82 percent more transmissible than previous variants. A Jan. 15 report from the Centers for Disease Control and Prevention (CDC) said that the strain is spreading so quickly that it is projected to become the dominant variant in the U.S. by March.

The CDC has reported three new variants in the U.S., with B.1.1.7 being the most prevalent. As of Feb. 14, the variant has already resulted in 1,173 COVID cases in 40 states across the country. The only states that have not reported cases of the U.K. variant are Arkansas, Idaho, Mississippi, Montana, Nebraska, North Dakota, Oklahoma, Rhode Island, South Dakota, Vermont, and West Virginia. According to the CDC, Florida has the most cases of the U.K. strain with 379.
