8 maj 2024 · Throughout the COVID-19 pandemic, SARS-CoV-2 variants have been designated as variants of concern (VOCs) and variants of interest (VOIs) on the basis of their potential to replace previously...
5 sty 2022 · Two weeks after the second vaccination with BNT162b2 in index patients, transmission of the alpha variant was 68% (95% CI, 52 to 79) lower than transmission of this variant from...
27 lip 2021 · Recently, three highly prevalent variants have been reported. These are the variant Alpha (B.1.1.7, 501Y.V1), the variant Beta (B.1.351, 501Y.V2), and the variant Gamma (P.1, 501Y.V3).
30 wrz 2021 · Using the parsimonious SARS-CoV-2 two-variant transmission model, we investigated the sensitivity of a VOC with immune-escape properties (VOC E) to the timing and properties of a VOC-targeted...
1 gru 2021 · There are many reasons for the paucity of robust empirical evidence on transmission of SARS-CoV-2 and the effectiveness of mitigation measures. It is extremely difficult to measure infectious SARS-CoV-2 virus in real world contexts, especially when airborne.
4 lis 2021 · SC2-VLPs provide a platform for rapid testing of viral variants outside of a biosafety level 3 setting and demonstrate N mutations and particle assembly to be mechanisms that could explain the increased spread of variants, including B.1.617.2 (Delta, which contains the R203M mutation). A new tool to probe SARS-CoV-2 variants.
4 kwi 2022 · Abstract. Coronavirus Disease 2019 (COVID-19) has caused tremendous losses to the world. This study addresses the impact and diffusion of the five major new coronavirus variants namely Alpha, Beta, Gamma, Eta, and Delta lineage.
