The United States has reported at least 2,753 cases of the coronavirus variants first spotted in the UK, South Africa and Brazil, according to the US Centers for Disease Control and Prevention.
Genomic sequencing has turned up cases of the three top variants of concern in 47 states, Washington, DC and Puerto Rico.
The CDC says this does not represent the total number of such cases circulating in the US -- just those detected by analyzing positive samples.
UK variant: The vast majority of these cases -- 2,672 -- are the more contagious variant known as B.1.1.7, which was originally detected in the UK. This variant has been found in 46 states, Puerto Rico and Washington, DC. About 24% of cases are in Florida.
South Africa variant: There have been 68 cases of a variant first seen in South Africa, called B.1.351, in 16 states and Washington, DC.
Brazil variant: 13 total cases of the P.1 variant first linked to Brazil have been discovered in 7 states.
