PRO/AH/EDR> COVID-19 update (495): animal, cat, transmission model
COVID-19 -- Worldwide/UnknownThe evolutionary mechanisms by which SARS-CoV-2 viruses adapt to mammalian hosts and, potentially, escape human immunity depend on the ways genetic variation is generated and selected within and between individual hosts. Using domestic cats as a model, we show that SARS-CoV-2 consensus sequences remain largely unchanged over time within hosts, but dynamic sub-consensus diversity reveals processes of genetic drift and weak purifying selection. Transmission bottlenecks Read more [...]
