Variants of severe acute respiratory syndrome coronavirus 2 ( SARS-CoV-2) are viruses that, while similar to the original, have genetic changes that are of enough significance to lead virologists to label them separately. SARS-CoV-2 is the virus that causes coronavirus disease 2019 (COVID-19).
Feb 6, 2023 · 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.
Jun 5, 2024 · COVID-19 variants: It is usual for viruses to change and evolve as they spread between people over time. When these changes become significantly different to a previously detected virus, these new virus types are known as “variants.”
Mar 27, 2024 · From May 2021 onwards, WHO began assigning simple, easy-to-say labels for key variants. Considerable progress has been made in establishing and strengthening a global system to detect signals of potential VOIs or VOCs and rapidly assess the risk posed by SARS-CoV-2 variants to public health.
May 30, 2024 · A new variant of COVID-19, known as FLiRT, is now the most dominant strain in the U.S. This variant, which evolved from the omicron strain, is characterized by changes in its spike protein — the part of the virus that binds to host cells.
Sep 1, 2023 · The World Health Organization (WHO) names new coronavirus variants using the letters of the Greek alphabet, starting with the Alpha variant, which emerged in 2020. Below is a list of—and information about—some of the variants that have been top-of-mind.
Nov 20, 2023 · What are variants of SARS-COV-2, the virus that causes COVID-19? It is usual for viruses to change and evolve as they spread between people over time. When these changes become significantly different to a previously detected virus, these new virus types are known as “variants.”
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.
The Search For Covid-19 Variants. Sequencing the genome of SARS-CoV-2 allows scientists to identify emerging variants. Vaccine Variants. Dr. Jennifer Nuzzo, senior scholar at the Center for Health Security. The graphic and accompanying video detail the importance of sequencing the DNA of SARS-CoV-2, the virus that causes COVID-19.
Nov 15, 2023 · Learn more about the COVID-19 variants, including the Omicron variant, and what that means for people’s health.
