Cumulative number of variants sequences identified over time by sample collection date.

Variants of concern have evidence of an increase in transmissibility, more severe disease (increased hospitalizations or deaths), significant reduction in neutralization by antibodies generated during previous infection or vaccination, reduced effectiveness of treatments or vaccines, or diagnostic detection failures.

For more information on these variants of concern visit CDC's Variant Surveillance or Wisconsin DHS Emerging SARS-CoV-2 Variants.

Cumulative number of variants sequences identified over time by sample collection date.

Variants of Interest contain specific mutations that have been associated with changes to receptor binding, reduced neutralization by antibodies generated against previous infection or vaccination, reduced efficacy of treatments, potential diagnostic impact, or predicted increase in transmissibility or disease severity.

For more information on these variants of concern visit CDC's Variant Surveillance or Wisconsin DHS Emerging SARS-CoV-2 Variants.
