New COVID-19 Variants
Updated Jan. 15, 2021
What we know
Viruses constantly change through mutation, and new variants of a virus are expected to occur over time. Sometimes new variants emerge and disappear. Other times, new variants emerge and persist. Multiple variants of the virus that causes COVID-19 have been documented in the United States and globally during this pandemic.
The virus that causes COVID-19 is a type of coronavirus, a large family of viruses. Coronaviruses are named for the crown-like spikes on their surfaces. Scientists monitor changes in the virus, including changes to the spikes on the surface of the virus. These studies, including genetic analyses of the virus, are helping us understand how changes to the virus might affect how it spreads and what happens to people who are infected with it.
Multiple COVID-19 variants are circulating globally:
In the United Kingdom (UK), a new variant called B.1.1.7 has emerged with an unusually large number of mutations. This variant spreads more easily and quickly than other variants. Currently, there is no evidence that it causes more severe illness or increased risk of death. This variant was first detected in September 2020 and is now highly prevalent in London and southeast England. It has since been detected in numerous countries around the world , including the United States and Canada.
In South Africa, another variant called 1.351 has emerged independently of the variant detected in the UK. This variant, originally detected in early October, shares some mutations with the variant detected in the UK. There have been cases caused by this variant outside of South Africa, but it has not been detected in the US.
In Brazil, a variant called P.1 emerged and was identified in four travelers from Brazil, who were tested during routine screening at Haneda airport outside Tokyo, Japan. This variant contains a set of additional mutations that may affect its ability to be recognized by antibodies. This variant has not been detected in the US
