""We have a number of reports from countries who are doing very detailed contact tracing, they're following asymptomatic cases, they're following contacts and they're not finding secondary transmission onwards – it's very rare," she said. "
"However, after experts called her comments into question she told a live question and answer session the following day that her comments on asymptomatic spread were based on small number of studies of contact tracing and cluster investigations. She added that modelling estimates suggest that up to 40 per cent of transmission was by asymptomatic carriers."
'Modelling' - yeah, because that sounds like a reliable measure :) They did a fast walk-back on her comments, but the Wuhan study is pretty solid info.

Unfortunately buried in that Telegraph article:

I remember how well their modelling estimates worked for predicting the end of the world via climate change/global warming...haha.
