Tomasz Lipniacki, (Institute of Fundamental Technological Research, Warsaw, Poland)<\/p>\n<p>The basic reproduction number R0 of the coronavirus disease 2019 has been estimated to range between 2 and 4. We used an SEIR model that properly accounts for the distribution of the latent period and, based on empirical estimates of the doubling time in the near-exponential phases of epidemic progression in China, Italy, Spain, France, UK, Germany, Switzerland and New York State, we estimated that R0 lies in the range 4.7-11.4. We explained this discrepancy by performing stochastic simulations of model dynamics in a population with a small proportion of super-spreaders.<\/p>\n<p>The novel SARS-CoV-2 Variant of Concern (VOC)-202012\/01 (also known as B.1.1.7), first collected on September 20, 2020, in Kent, UK, is a rapidly growing lineage. Based on GISAID we estimated that the replicative advantage of the VOC-202012\/01 lineage is in the range of 1.85-2.17 with respect to the 20A.EU1 variant (dominating in England in November 2020) and in the range of 1.99-2.36 with respect to other non-VOC-202012\/01 strains. Such significant replicative advantage and the fact that London serves as major international transportation hub suggest that the VOC-202012\/01 strain will likely become globally dominant, hindering containment of the COVID-19 epidemics prior to mass vaccinations.<\/p>\n<p>See also:<br \/>\nSARS-CoV-2 Variant Under Investigation 202012\/01 has more than two fold replicative advantage, Frederic Grabowski, Grzegorz Preibisch, Marek Kocha\u0144czyk, Tomasz Lipniacki<br \/>\n<a class=\"moz-txt-link-freetext\" href=\"https:\/\/doi.org\/10.1101\/2020.12.28.20248906\">https:\/\/doi.org\/10.1101\/2020.12.28.20248906<\/a><\/p>\n<p>Super-spreading events initiated the exponential growth phase of COVID-19 with \u211b0 higher than initially estimated, Marek Kocha\u0144czyk, Frederic Grabowski and Tomasz Lipniacki<br \/>\n<a class=\"moz-txt-link-freetext\" href=\"https:\/\/doi.org\/10.1098\/rsos.200786\">https:\/\/doi.org\/10.1098\/rsos.200786<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Szanowni Pa\u0144stwo, pierwsze w roku 2021 Konwersatorium im.
