The Swiss Minister of Health, Mr. Berset, has proclaimed that children do not transmit CoV2 to others. Can somebody please direct me to any peer-reviewed paper describing this astonishing finding? I seem to have missed it.

[before you jump at me: I know that kids rarely develop overt COVID. What I am asking, is why Berset thinks that asymptomatic kids would not transmit to others (e.g. their parents). Let's not conflate illness and infectivity].

From their "clarifications" it seems that Koch etc conflated infectivity and illness. Coming from people in their position, that's plain scary.
