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 respiratory...
SARS-CoV-2 has consistently mutated over the course of the pandemic, resulting in variants that are different from the original SARS-CoV-2 virus. Throughout the COVID-19 pandemic, many variants of SARS-CoV-2 have been found in the United States and globally.
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.”
Jun 5, 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.
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.
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).
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.
Apr 9, 2024 · COVID-19 (coronavirus disease 2019) is a disease caused by a virus named SARS-CoV-2. It can be very contagious and spreads quickly. Over one million people have died from COVID-19 in the United States.
