Map Shows Which U.S. States Have Reported New COVID Strains

A map published by the Centers for Disease Control and Prevention (CDC) shows which states have reported cases of the new coronavirus variants, as overall virus cases in the U.S. continue to decline.

According to the map, three main variants of the novel virus are spreading across the U.S.: the B.1.1.7 variant, the B.1.351 variant and the P.1 variant.

The map shows the B.1.1.7 variant, which is believed to have first emerged in the U.K. in September, as the most prominent variant in the U.S. This variant has accounted for at least 1,661 cases across 44 states.

According to the map, Florida has the most reported cases of B.1.1.7, with 433, followed by Michigan, with 210, and California, with 195. As the CDC notes, this variant is associated with increased transmissibility, but "early reports found no evidence to suggest that the variant has any impact on the severity of disease or vaccine efficacy."

Other states that have seen high case counts of the B.1.1.7 variant are Georgia, which has reported 85 cases; New York, with 82; Colorado, with 71; Texas, with 60; and New Jersey, with 50.

The B.1.351 variant is the second most prominent in the U.S. and has been reported in 10 states, with a total of 22 cases, according to the map.

According to the CDC's report on emerging variants, the B.1.351 strain was first identified in South Africa, but there is currently "no evidence to suggest that this variant has any impact on disease severity."

There are at least eight cases of the B.1.351 variant in Maryland and three cases in Virginia. California, Texas, Illinois, South Carolina, North Carolina, Connecticut and Massachusetts have also seen at least one case.

The third variant identified by the CDC is the P.1 variant, which was first detected in Japan among four travelers from Brazil.

"There is evidence to suggest that some of the mutations in the P.1 variant may affect its transmissibility and antigenic profile, which may affect the ability of antibodies generated through a previous natural infection or through vaccination to recognize and neutralize the virus," the CDC wrote.

According to the CDC map, there are at least five reported cases of the P.1 variant across four states. Minnesota has two confirmed cases, while Oklahoma, Florida and Maryland have all reported one case.

The variants map comes as the news about case counts remains positive. According to a virus tracker from the CDC, as of February 20 the nation had a seven-day moving average number of at least 65,990 cases, which is a significant decrease from the previous month. The weekly average number of cases was 193,447 on January 20.

The decline in cases could be a result of the increasing number of vaccine doses administered. According to the CDC's vaccine tracker, at least 63,090,634 doses have been administered across the U.S.

Newsweek reached out to the CDC for comment but did not receive a response in time for publication.
