...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.

...Some scientists expressed surprise at Dr Van Kerkhove's initial comments.
Liam Smeeth, professor of clinical epidemiology at the London School of Hygiene and Tropical Medicine, said evidence so far suggests that asymptomatic and pre-symptomatic are an "important source of infection to others".
"There remains scientific uncertainty, but asymptomatic infection could be around 30 per cent to 50 per cent of cases. The best scientific studies to date suggest that up to half of cases became infected from asymptomatic or pre-symptomatic people," he said.

Here's a link to a vid from yesterday's Q & A with Drs Van Kerkhove and Ryan. In the first 5-6 min Dr Van Kerkhove clarifies her response from the previous day that seemed to stir things up wrt asymptomatic transmission. A simple misunderstanding, not nearly as nefarious as journalists would have you believe.
Not a whole lot of specific information provided in the 43 min. But that simply underscores how little we know about Covid-19 and why they speak in generalities.
