At least 2,581 cases of coronavirus variants first spotted in the UK, South Africa and Brazil have been reported in the United States, according to data updated Tuesday by the US Centers for Disease Control and Prevention.
The vast majority of these cases, 2,506, are the more contagious variant known as B.1.1.7, which was originally detected in the UK. This variant has been found in 44 states, Puerto Rico and Washington, DC. About a quarter of these were found were in Florida.
In addition, 65 cases have been reported of a variant initially seen in South Africa, called B.1.351, in 16 states and Washington, DC.
Lastly, 10 cases of the P.1 variant first linked to Brazil have been discovered among five states.
CDC says this does not represent the total number of such cases circulating in the US, but rather just those that have been found by analyzing positive samples. The agency cautions that its numbers may not immediately match those of state and local health departments.
