As of 1 July 2020, more than 10 million people been confirmed to have infected by SARS-CoV-2,
resulting in more than 500,000 deaths. No specific antiviral treatment for the SARS-CoV-2 is
currently available, but existing medication could be repurposed.
The investigators therefore propose to conduct an open-label randomized controlled trial on a
short course of interferon β-1b and ribavirin combination treatment for patients hospitalized
for COVID-19 infection.
