Overall, at least 12,053 cases of coronavirus variants first spotted in the UK, South Africa and Brazil have been reported in the US, according to the Centers for Disease Control and Prevention.
Most of these cases, 11,569, are the more contagious variant known as B.1.1.7, which was originally detected in the UK. This variant has been found in 49 states, Puerto Rico and Washington, DC.
In addition, there are 312 reported cases of a variant first identified in South Africa, called B.1.351, which has been detected in 30 states and Washington, DC, and then 172 reported cases of the P.1 variant first identified in Brazil have been discovered in 22 states.
According to CDC data, three states — California, Florida and Michigan — have the highest total numbers of variant cases. Florida leads with 2,351 reported cases of the B.1.1.7 variant, 49 cases of P.1 and 15 cases of B.1.351.
Michigan has the second highest number of reported variants cases, with 1,237 cases of B.1.1.7 and five cases of B.1.351 and California has reported 822 cases of the B.1.1.7 variant, 33 cases of P.1 and 10 cases of B.1.351.
