Recombination: A process in which the genomes of two SARS-CoV-2 variants combine during the viral replication process to form a new variant that is different from both parent lineages. This may occur when a person is infected with two variants at the same time. The lineage that results from recombination is called a “recombinant.”.
Mar 27, 2024 · Tracking SARS-CoV-2 variants. All viruses, including SARS-CoV-2, the virus that causes COVID-19, change over time. Most changes have little to no impact on the virus’s properties. However, some changes may affect the virus’s properties, such as how easily it spreads, the associated disease severity, or the performance of vaccines ...
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 18, 2023 · A Variant of Interest (VOI) is a term used to describe a SARS-CoV-2 variant with changes that are known to affect how the virus behaves or its potential impact on human health. This can include, for example, its ability to spread, its ability to cause serious disease, or how easily it may be detected or treated.
Nov 20, 2023 · 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.
Mar 24, 2021 · Recently, two more SARS-CoV-2 variants, B.1.427 and B.1.429, which were first detected in California, have been shown to be approximately 20% more transmissible than preexisting variants and have ...
