have you read the report? It's really not a 'debunking'.
For a start: "The researchers said that their findings did not show that the virus couldn’t be passed on by asymptomatic carriers, and they didn’t suggest that their findings were generalisable."
And: "But, he added, “there is plenty of evidence elsewhere showing that people infected with covid-19 may be temporarily asymptomatic and infectious, before going on to develop symptoms.”
Also: Song said, “It is very important to say that these asymptomatic cases were identified shortly after the relaxation of a very stringent lockdown in Wuhan that lasted more than 70 days. By then, the epidemic in Wuhan had been effectively brought under control. It is too early to be complacent, because of the existence of asymptomatic positive cases and high level of susceptibility in residents in Wuhan.”
