Drugmakers worldwide are rushing to develop treatments for the flu-like illness caused by the new coronavirus that has killed more than 374,000 globally since it first emerged late last year in China.
"It would be difficult to conduct clinical trials at home due to low number of new cases and we understand discussions are underway with European countries for trials," Korea Centre for Disease Control and Prevention deputy director Kwon Jun-wook said on its daily briefing. There is currently no treatments for COVID-19 and human trials of several existing antiviral drugs have yet to show full efficacy.
