10 cze 2024 · Here we leverage genetic data on the transmission of three (Alpha, Delta and Omicron BA.1) variants of SARS-CoV-2 throughout England, to unpick the roles that climate and public-health...
6 dni temu · ECDC utilises three categories of variant classification to communicate increasing levels of concern about a new or emerging SARS-CoV-2 variant: variant under monitoring (VUM), variant of interest (VOI) and variant of concern (VOC).
10 cze 2024 · Samples collected from 96 unvaccinated COVID-19 patients were deep sequenced. The consensus sequences of the samples matched lineages B.1.1.7 (VOC Alpha), B.1.617.2 (Delta) and P.1 (Gamma) (33, 30 and 33 patients, respectively).
20 cze 2024 · The first nationwide outbreak of COVID-19 in Vietnam started in late April 2021 and was caused almost exclusively by a single Delta lineage, AY.57. In early 2022, multiple Omicron variants co ...

As of 4 July 2024 - 1722UTC, 101 countries shared 23,837 GRA (BA.2.86+BA.2.86.*) genome sequences with unprecedented speed from sample collection to making these data publicly accessible via GISAID EpiCoV, in some cases within less than 24 hours. Map of tracked variant occurrence.
18 cze 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.
11 cze 2024 · When specifically evaluating interactions with SARS-CoV-2 variants (Omicron, Kappa, and Delta), the GQDs with the most negative affinity energy values are consistently GQD-E. For example, for the Omicron variant, GQD-E shows a ΔG Binding of −158.1676 +/− 6.019 kJ/mol, while GQD-A shows −104.0118 +/− 2.898 kJ/mol.
