The bars in this graph represent the number of SARS-CoV-2 sequences available in public repositories each week since December 2020. The blue bars show sequences published to public repositories by CDC (NS3 and contracts). The light gray bars show the sequences published to public repositories by state and local public health laboratories. The blue dotted line represents CDC’s current weekly sequencing goal. The published sequences are reported by week ending date. These numbers do not include academic contracts or all public health laboratory sequences that have been published. Sequences generated by CDC and contract laboratories are available to inform public health actions before they are published. Delays in processing data may impact displayed results. Weekly totals reflect date of submission and may change over time as sequences are published in databases.
*Numbers will be updated every Sunday by 7:00 pm.
