Abstract: Determining the transmissibility, prevalence and patterns of movement of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections is central to our understanding of the impact of the pandemic and to the design of effective control strategies. Phylogenies (evolutionary trees) have provided key insights into the international spread of SARS-CoV-2 and enabled investigation of individual outbreaks and transmission chains in specific settings. Phylodynamic approaches combine evolutionary, demographic and epidemiological concepts and have helped track virus genetic changes, identify emerging variants and inform public health strategy. Here, we review and synthesize studies that illustrate how phylogenetic and phylodynamic techniques were applied during the first year of the pandemic, and summarize their contributions to our understanding of SARS-CoV-2 transmission and control. In this Review, the authors describe how phylogenetic and phylodynamic methods provide insight into viral evolution, focusing on the SARS-CoV-2 pandemic. The approaches reveal routes and timings of transmission events, and they can assess the effectiveness of various intervention measures aimed at controlling the virus.

Differential responses of SARS-CoV-2 variants to environmental drivers during their selective sweeps
Tom Smith,Swapnil Mishra,Ilaria Dorigatti,Mahika K. Dixit,Michael Tristem,William D. Pearse +5 more
TL;DR: Environmental drivers of SARS-CoV-2 transmission vary across viral variants. While colder temperatures enhance the transmission of the Alpha variant, the Delta and Omicron variants show limited impact of climate on their transmission.
Phylodynamic approaches to studying avian influenza virus
TL;DR: How phylodynamics can be used to examine viral spread within and between wild or domestic bird populations at various geographical scales, identify factors associated with virus dispersal, and determine the order and timing of virus lineage movement between geographic regions or poultry production systems is assessed.

TL;DR: Phylogeographic inference of SARS-CoV-2 Delta wave in Texas, USA using a novel spatial transmission count statistic. The study investigates the spread of the Delta variant in Texas and finds that urban centers were the main sources of the epidemic, while rural areas were driven by repeated introductions.

TL;DR: A SARS-CoV-2 variant carrying the Spike protein amino acid change D614G has become the most prevalent form in the global pandemic, and it is found that the G614 variant grows to higher titer as pseudotyped virions.
