Scientists at EPFL have uncovered a cunning strategy that SARS-CoV-2, the virus that causes COVID-19, uses to increase its infectivity. SARS-CoV-2, the novel coronavirus first identified in late 2019, has since spread globally, leading to the COVID-19 pandemic that has affected millions. As countries grapple with its health, social, and economic impacts, scientists and researchers worldwide have been working tirelessly to understand the virus better and develop effective treatments and vaccines. In a new study, researchers at EPFL have unveiled a novel mechanism by which SARS-CoV-2 increases its infectivity. The study focuses on the virus's notorious Spike protein, which allows it to enter and infect human cells.
