Transmissibility and spread of SARS-CoV-2 variants.

Campbell Finlay u. a.: Increased transmissibility and global spread of SARS-CoV-2 variants of concern as at June 2021, in: Euro Surveillance Vol. 26, Issue 24 (2021), pii=2100509, online in: https://doi.org/10.2807/1560-7917.ES.2021.26.24.2100509. The authors present a global analysis of the spread of recently emerged SARS-CoV-2 variants and estimate changes in effective reproduction numbers at country-specific level using sequence data from GISAID. Nearly all investigated countries demonstrated rapid replacement of previously circulating lineages by the World Health Organization-designated variants of concern, with estimated transmissibility increases of 29% (95% CI: 24–33), 25% (95% CI: 20–30), 38% (95% CI: 29–48) and 97% (95% CI: 76–117), […]
