The United States has reported at least 618 cases of coronavirus variants across 33 states, according to data posted Thursday by the US Centers for Disease Control and Prevention.
The vast majority (611) of these cases are the more contagious variant known as B.1.1.7, which was originally detected in the United Kingdom. Florida has the highest count, with 187 cases, and California follows with 145. The rest are scattered across a few dozen states.
In addition, there are five cases of the variant called B.1.351, which was initially seen in South Africa. Two cases are in South Carolina, and three in Maryland.
Lastly, Minnesota has identified two cases of the P.1 strain, first linked to Brazil.
The CDC says this does not represent the total number of such cases circulating in the US, but just those that have been found by analyzing positive samples.
