May 8, 2024 · Variants of Concern (VOC) As of 3 March 2023, ECDC has de-escalated BA.2, BA.4 and BA.5 from its list of SARS-CoV-2 variants of concern (VOC), as these parental lineages are no longer circulating. ECDC will continue to categorise and report on specific SARS-CoV-2 sub-lineages in circulation that are relevant to the epidemiological situation.
May 13, 2024 · The version of the Covid-19 virus behind the latest spike in infections shares many of the same symptoms as earlier variants of Sars-CoV-2 : a sore throat, fatigue, headache and a cough ...
May 13, 2024 · Two of these mutations—456 and 346—eliminate binding sites for antibodies that neutralize SARS-CoV-2. However, those same antibody binding sites are also important for the virus to bind to and enter cells. So in evading antibodies, these FLiRT variants may have also lost some ability to bind to their receptor.
May 8, 2024 · The WHO SARS-CoV-2 variant risk-evaluation framework 12 is designed to assist in evaluating the risk posed by emerging SARS-CoV-2 variants based on the evidence available and the level of ...

May 24, 2024 · Some variants grow and persist in the community while many variants simply fi zzle out. Most variants do not have a meaningful impact on things like hospitalization rates, severity, or infectivity. California follows the CDC’s SARS-CoV-2 Variant Classifications and Definitions (cdc.gov) .
May 28, 2024 · KP.2 is a member of a group of SARS-CoV-2 variants sometimes called “FLiRT” variants (so named because of the technical names for their mutations: F for L at position 456, and R for T at position 346). Other FLiRT variants, including KP.1.1, have also been identified as circulating in the US, but have not yet become as widespread as KP.2.
May 15, 2024 · SARS-CoV-2 (the virus that causes COVID-19) evolves over time, which results in a new strain (variant) of the virus. With COVID-19, new variants continue to emerge, with some variants disappearing while others will persist. The SARS-CoV-2 variants are classified into four groups: new variants of concern, variants of high consequence, variants being monitored and variants of interest. The AMA ...
