BEIJING – Share prices of Chinese biotechs that partner with Gilead Science Inc. have surged in China this week, after the U.S. firm’s remdesivir was identified as the most promising drug candidate to treat 2019-nCoV.

The drug screens prompted by the SARS and MERS outbreaks have been useful for quickly identifying drug candidates. But in terms of their epidemiology, “SARS and MERS were different from this coronavirus,” Allison McGeer explained at a Feb. 3 webinar by Evercore ISI.

At this very early point in the emerging 2019-nCoV outbreak, knowledge about the virus is insufficient to predict what shape that outbreak will ultimately take. But knowledge about the virus is accumulating at remarkable speed, and experience with other viruses is helping to shape the response to the newest coronavirus threat. 2019-nCoV, sometimes called Wuhan coronavirus after its source, is the third coronavirus after SARS-CoV and MERS-CoV with the potential to cause serious illness and death that has emerged since the beginning of the 21st century.

HONG KONG – In another example that communication is proving as difficult as containment in the current coronavirus outbreak, China’s state media reported, to increasing skepticism, that a traditional Chinese medicine (TCM) oral liquid could inhibit the new coronavirus.
