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.

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.

TL;DR: Heterogeneous YF-associated profiles among the various genera of primates were detected and differences in susceptibility, viral load, and mortality rates should be considered in strategic surveillance of epizootics and control measures for YF.

TL;DR: In this paper, the authors used individual-level patient records following hospitalisation with suspected or confirmed COVID-19 to document the extensive shocks in hospital fatality rates that followed Gamma's spread across 14 state capitals, and in which more than half of hospitalised patients died over sustained time periods.

TL;DR: Evaluating the performance of a method based on phenol-chloroform (PC) and 2 commercial methods for RNA extraction, adapting their protocols for FFPE tissues showed favorable results, demonstrating the viability of the RNA.
