Where is the UK coronavirus variant in the US? States that have identified the mutation — so far

The UK coronavirus variant is known as B.1.1.7

In the ongoing battle against the novel coronavirus, a more contagious mutation of the pathogen that was first identified in the United Kingdom late last year has since been found in the United States, and federal health officials have recently voiced concerns that the variant – known as B.1.1.7 – could become the dominant strain in the U.S. by March. 

Thankfully, at this time, experts are confident that existing coronavirus vaccines should be effective in protecting against the strain, and, for now, it isn’t thought that the variant causes more severe illness or is transmitted in a different way than COVID-19 – meaning mask-wearing, social distancing, and handwashing, among other preventive measures, should still work. 

Additionally, the much-discussed antiviral drug Remdesivir, which became the first FDA-approved treatment for COVID-19 last fall, should be effective against new strains, the Gilead Sciences CEO recently said.


Colorado was the first U.S. state to identify the mutation, though it has since been discovered in numerous other states, including New York, California, Florida, Georgia, Pennsylvania, WisconsinIndiana and Minnesota,among others. 

According to estimates from the Centers for Disease Control and Prevention (CDC), more than 300 cases of the variant have been identified across the U.S. so far. Read on to see which states have reported cases of B.1.1.7.
