Chinese scientists are testing two antiviral drugs against the new coronavirus and preliminary clinical trial results are weeks away, the co-chair of a World Health Organization (WHO) meeting said on Wednesday.

Dr. Marie-Paule Kieny, a former WHO virologist, co-chaired the two-day, closed-door research forum in Geneva of more than 300 scientists and researchers, including some who took part virtually from China and Taiwan.

"The Chinese colleagues are very eager to participate in protocols which are being defined so that all the clinical trials are done according to the same standards and are looking towards the same outcome," she told a news conference. "They were very interested in working on such a master protocol."
