CDC update about the Variants in U.S.

Updated on Apr. 2, 2021

Global Variant Reports

B.1.1.7:

This variant was first identified in the US in December 2020.
It was initially detected in the UK.

B.1.351:

This variant was first identified in the US at the end of January 2021.
It was initially detected in South Africa in December 2020.

P.1:

This variant was first detected in the US in January 2021.
P.1 was initially identified in travelers from Brazil, who were tested during routine screening at an airport in Japan, in early January.

B.1.427 and B.1.429:

These two variants were first identified in California in February 2021 and were classified as VOCs in March 2021.

These variants seem to spread more easily and quickly than other variants, which may lead to more cases of COVID-19. An increase in the number of cases will put more strain on health care resources, lead to more hospitalizations, and potentially more deaths.

So far, studies suggest that antibodies generated through vaccination with currently authorized vaccines recognize these variants. This is being closely investigated and more studies are underway.
