That study is an extremely weak support to the claim that this virus can't spread asymptomatically - it's nearly useless for that purpose. They only studied a small number of people at the very tail end of the infection who showed that they had some evidence of virus in them. They did not look at whether those patients actually had an active infection - they could have simply been detecting remnants of dead virus in their systems. They certainly didn't look at all at people in the incubation stage pre-symptoms.
- enriquec 6y agoNature is one of the two top journals in the world and their conclusions directly contradict what you're saying. This was a study of 10,000,000 people.

In ~30k people who recovered from covid, 107 tested positive for covid a second time. Roughly ~1000 people were in contact with asymptomatic carriers, but none (as in 0) tested positive for covid.

The numbers I find are ~20%. Sure, that isn't negligible, but I can understand why experts would base a strategy on those with symptoms.
