New York: 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.
The coronaviruses that cause SARS and Covid-19 have spike proteins that move into active and inactive positions, and the study indicates how those molecular movements may make the Covid-19 virus more infectious compared to the SARS virus, according to researchers, including one of Indian-origin named Vivek Govind Kumar.
