A team of researchers has discovered one reason that likely makes SARS-CoV-2, the virus that causes Covid-19, so much more infectious than SARS-CoV-1, which caused the 2003 SARS outbreak. We discovered in these simulations that SARS-CoV-1 and SARS-CoV-2 have completely different ways of changing their shape, and on different time scales," said researcher from the University of Arkansas.
