Journal ArticleDOI

Nicholas G Davies,Sam Abbott,Rosanna C. Barnard,Christopher I Jarvis,Adam J. Kucharski,James D Munday,Carl A. B. Pearson,Timothy W Russell,Damien C. Tully,Alex D. Washburne,Tom Wenseleers,Amy Gimma,William Waites,Kerry L. M. Wong,Kevin van Zandvoort,Justin D. Silverman,Karla Diaz-Ordaz,Ruth H. Keogh,Rosalind M Eggo,Sebastian Funk,Mark Jit,Katherine E. Atkins,Katherine E. Atkins,W. John Edmunds +23 more
TL;DR: Using a variety of statistical and dynamic modeling approaches, the authors estimate that this variant has a 43 to 90% (range of 95% credible intervals, 38 to 130%) higher reproduction number than preexisting variants, and a fitted two-strain dynamic transmission model shows that VOC 202012/01 will lead to large resurgences of COVID-19 cases.

Atkins,W. John Edmunds +22 more
TL;DR: A novel SARS-CoV-2 variant, VOC 202012/01, emerged in southeast England in November 2020 and appears to be rapidly spreading towards fixation as mentioned in this paper.
Journal ArticleDOI

Barnard,Yung Wai D. Chan,Megan Auzenbergs,Amy Gimma,C. Julian Villabona-Arenas,Nicholas G Davies +50 more
TL;DR: In this paper, the authors compared the performance of testing with either PCR or lateral flow antigen (LFA) tests at the end of quarantine and daily LFA testing without quarantine, against the current 14-day quarantine strategy.
Journal ArticleDOI

Kucharski,Billy J Quilty,Hamish Gibbs,Samuel Clifford,Petra Klepac +52 more
TL;DR: The model findings highlight the substantial health and economic value of introducing SARS-CoV-2 vaccination and the net monetary values of physical distancing scenarios may be negative from societal perspective if the daily national economy losses are persistent and large.
Journal ArticleDOI
Association of tiered restrictions and a second lockdown with COVID-19 deaths and hospital admissions in England: a modelling study.
Nicholas G Davies,Rosanna C. Barnard,Christopher I Jarvis,Timothy W Russell,Malcolm G Semple,Malcolm G Semple,Mark Jit,W. John Edmunds +7 more
TL;DR: In this article, the authors examined the impact of lockdown stringency, timing, and duration on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission and hospital admissions and deaths from COVID-19.
