TL;DR: In this article, the authors used a two-category dynamical model that integrates genomic and mortality data to estimate that P.1 may be 1.7-to 2.4-fold more transmissible and that previous (non-P.1) infection provides 54 to 79% of the protection against infection with P.
Journal ArticleDOI
Test sensitivity is secondary to frequency and turnaround time for COVID-19 screening.

TL;DR: It is demonstrated that effective screening depends largely on frequency of testing and speed of reporting and is only marginally improved by high test sensitivity, and should prioritize accessibility, frequency, and sample-to-answer time.

TL;DR: It is concluded that surveillance should prioritize accessibility, frequency, and sample-to-answer time; analytical limits of detection should be secondary.

TL;DR: In this paper, the emergence and circulation of a new SARS-CoV-2 variant of concern, lineage P.1, that acquired 17 mutations, including a trio in the spike protein (K417T, E484K and N501Y) associated with increased binding to the human ACE2 receptor.
