>>>The spread of Covid-19 by someone who is not showing symptoms appears to be rare, Maria Van Kerkhove, the World Health Organization's technical lead for coronavirus response and head of the emerging diseases and zoonoses unit, said during a media briefing in Geneva on Monday.

>It's rare for the same reason as asymptomatic cases appear "rare" until you conduct community testing. At this stage we can't even reliably measure the asymptomatic cohort, let alone assess how they got it. Lets not forget that WHO also originally misled the world that the virus appears not to have any human spread at all because that also appeared "rare" due to lack of data. More realistically you might anticipate WHO calling for international community testing to allow more helpful advice, but WHO appears opposed to that idea along with numerous health officials and politicians. Not sure why, ought to be a no-brainer.
Not to worry: On Tuesday, WHO walked that statement back issuing a clarification that better defines what they were referring to when they used the term asymptomatic spread, which they now estimate at around 16 percent of cases.
