SARS‑CoV‑2 is a strain of the species severe-acute-respiratory-syndrome-related coronavirus (SARSr-CoV), as is SARS-CoV-1, the virus that caused the 2002–2004 SARS outbreak. [2] [17] There are animal-borne coronavirus strains more closely related to SARS-CoV-2, the most closely known relative being the BANAL-52 bat coronavirus.
Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus. Most people infected with the virus will experience mild to moderate respiratory illness and recover without requiring special treatment. However, some will become seriously ill and require medical attention.
Oct 6, 2020 · Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly transmissible and pathogenic coronavirus that emerged in late 2019 and has caused a pandemic of acute...
Mar 27, 2024 · It remains critical that global systems to detect signals of potential variants of interest (VOIs) or variants of concern (VOCs) and rapidly assess the risk posed by SARS-CoV-2 variants to public health are maintained, and data are shared, according to good principles and in a timely fashion.
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.”
Sep 1, 2023 · Variants of SARS-CoV-2, the virus that causes COVID-19, have been reported in many countries around the world. Learn more about the current variants of concern. CDC provides credible COVID-19 health information to the U.S.
Jun 28, 2024 · Since 2020, SARS-CoV-2, the virus that causes COVID-19, has been spreading and changing globally. These changes have led to the detection of variants in many countries around the world. The more significant of these variants are grouped in three different ways – variants under monitoring, variants of interest and variants of concern.
Dec 12, 2021 · Severe acute respiratory syndrome coronavirus 2 ( SARS-CoV-2 ), also known as “the novel coronavirus” due to genome variation relative to previously identified coronaviruses, is a positive sense RNA virus and the etiological agent of COVID-19.
Mar 27, 2024 · COVID-19, also called coronavirus disease 2019, is an illness caused by a virus. The virus is called severe acute respiratory syndrome coronavirus 2, or more commonly, SARS-CoV-2. It started spreading at the end of 2019 and became a pandemic disease in 2020.
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.
