  • Coronavirus Variants and Mutations: Variants Tracker

    Updated Feb. 25, 2021
    By Jonathan Corum and Carl Zimmer

    Each coronavirus contains nearly 30,000 letters of RNA. This genetic information allows the virus to infect cells and hijack them to make new viruses.

    ... Over the course of the pandemic, a number of variants of SARS-CoV-2 have arisen. Some of them are raising worries that they may draw out the pandemic or make vaccines less effective.
    Feb. 23 Added the B.1.526 variant, which is spreading in New York City.
    Feb. 23 Studies suggest that a variant discovered in California is more contagious.
    Feb. 17 Maryland confirms its first case of the P.1 variant.
    Feb. 16 Massachusetts confirms its first case of the B.1.351variant.
    Feb. 15 Added the Q677 spike mutation, which was found in several lineages in the U.S.
    Feb. 15 B.1.351 is confirmed in a Connecticut resident hospitalized in New York City.
    Feb. 13 Studies suggest B.1.1.7 is likely more deadly than other circulating variants.
    Feb. 11 Illinois and North Carolina confirm their first cases of the B.1.351 variant.
    Feb. 7 South Africa stops using AstraZeneca’s vaccine against the B.1.351 variant.
    Feb. 7 The B.1.1.7 variant is doubling every 10 days in the United States.
    B.1.1.7 Variant of Concern 202012/01, or 501Y.V1 Emerged in Britain in December and is roughly 50 percent more infectious. Now detected in over 70 countries and 33 states.
    B.1.351 501Y.V2 Emerged in South Africa in December. Reduces the effectiveness of some vaccines.
    P.1 501Y.V3 Emerged in Brazil in late 2020. Has mutations similar to B.1.351.
    B.1 D614G Appeared in early 2020 and spread around the world.
    Several N501Y A defining mutation in several lineages, including B.1.1.7, B.1.351 and P.1. Helps the virus bind more tightly to human cells.
    Several E484K Appears in several lineages. May help the virus avoid some kinds of antibodies.
    Several K417 Appears in several lineages, including B.1.351 and P.1. May help the virus bind more tightly to cells.
    Several L452R Increasingly common in California, but not yet shown to be more infectious.
    Several Q677 Found in seven U.S. lineages, but not yet shown to be more infectious.
    B.1.427, B.1.429 CAL.20C Common in California, but not yet shown to be more infectious. Carries the L452Rmutation.
    B.1.526 Spreading in New York. One version carries the E484Kmutation, another carries S477N.
