Phylodynamic studies on SARS-CoV-2 and its application to improve viral detection and prevent transmission.
The extremely high human-to-human transmissibility of SARS-CoV-2 allows the generation of thousands of mutations within its genome fueling the evolution and selection of several viral lineages with different characteristics. While several of these lineages become rare, others largely increase in prevalence, potentially jeopardizing the efficacy of vaccines and epidemic control strategies. SARS-CoV-2 is widely spread globally and is still responsible for large mobility/mortality and economical burden. This project focus on investigating molecular factors that mediate genomic evolution of SARS-CoV-2 aiming to provide knowledge to advance current viral detection and transmission preventing strategies.
