Wisconsin SARS-CoV-2 (hCoV-19) Genomic Dashboard

enabled by data from GISAID

Number of sequences by selected time period of sample collection.

Cumulative number of sequences by date of sample collection.

Proportion of all sequence lineages over time by sample collection date. Variants of concern are shown in red, variants of interest are shown in purple, all other lineages are shown in blue.

Proportion of sequenced strains that are variants, over time by sample collection date.

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.

Proportion of sequenced strains matching the selected variant, over time by sample collection date.

Percentage of sequences identified as variants of concern by Healthcare Emergency Readiness Coalition (HERC) region, darker colors represent a greater proportion of variants identified. Hover over a region to see a breakdown of the variants of concern. Percentage is based on the number of sequences generated between:
