May 3, 2024 · To identify variants, scientists map the genetic material of viruses (known as sequencing) and then look for differences between them to see if they have changed. Since 2020, SARS-CoV-2, the virus that causes COVID-19, has been spreading and changing globally.
Feb 6, 2023 · What You Need to Know. New variants of SARS-CoV-2, the virus that causes COVID-19, will continue to occur. CDC coordinates collaborative partnerships which continue to fuel the largest viral genomic sequencing effort to date. The Omicron variant, which emerged in November 2021, has many lineages.
Sep 1, 2023 · Throughout the COVID-19 pandemic, many variants of SARS-CoV-2 have been found in the United States and globally. Scientists use multiple classification systems to describe and communicate similarities and differences between SARS-CoV-2 viruses. On This Page. Key Definitions. Types of Classification. Recombinants. Summary of Variant Classifications.
