Thank you for the links. I found it before as well with some quick googling but I felt the title deceptive after reading the actual studies linked [0] [1].

>>> The sequence of events suggests that the coronavirus may have been transmitted by the asymptomatic carrier.

>>> If the findings in this report of presumed transmission by an asymptomatic carrier are replicated, the prevention of COVID-19 infection would prove challenging. The mechanism by which asymptomatic carriers could acquire and transmit the coronavirus that causes COVID-19 requires further study.

>>> Considering the reported similarity in viral loads between asymptomatic and symptomatic patients [14] and that transmission of SARS-CoV-2 by asymptomatic or paucisymptomatic cases may be possible, even though there is no clear evidence as yet of asymptomatic transmission, the relatively high proportion of asymptomatic infections could have public health implications

No clear evidence of asymptomatic transmission. A lot of 'probably', 'suggests' as before. It's certainly a growing possibility, but not I'd not call it proven yet as a big factor.
